Title: Roof-insulation-panel mounting system with an extruded coupling-profile in between a lower supporting-gutter-profile and an upper shielding-gutter-profile.

FIELD OF THE INVENTION

The present invention relates to roof-insulation-panel mounting systems for working and storage spaces of greenhouses, industrial halls, warehouses, or the like. The invention in particular relates to such roof-insulation-panel mounting systems when they are specifically configured for and equipped with sandwich panels. Sandwich panels are known to comprise a strong upper surface sheet (for example a steel skin), a core of insulating material (for example a foam or fiberglass core}, and a strong lower surface sheet (for example also a steel skin). Such sandwich panels are economical, strong, and help to save energy while controlling the working and storage space’s temperature.

BACKGROUND TO THE INVENTION

Over the years different greenhouse builders have developed their own greenhouse supporting frame constructions with specific mounting frames, gutter systems, and connection means. Those mounting frames, gutter systems and connection means are specifically designed for connecting glass therewith.

Besides the glasshouse growing spaces where the horticultural products, like vegetables, fruits, flowers and plants, are grown, also special working and storage spaces are needed for processing and handling harvested horticultural products, as well as for storing all kinds of equipment. It is then preferred to locally provide those working and storage spaces with non-glass wall- and roof-insulation -panels, like said sandwich panels. For those working and storage spaces it is then also desired to keep on using as much as possible of the already selected supporting frame constructions that is to be used for the rest of the greenhouse.

However, for most greenhouse supporting frame constructions it goes that they are particularly unsuitable for covering them with roof-insulation-panels instead of glass. Over the years this has made it necessary to come up with specifically designed roof-insulation-panel mounting systems that can be connected to different types of greenhouse supporting frame constructions.

For example for Venlo-type greenhouse supporting frame constructions it is known to use a roof-insulation-panel mounting system that comprises assemblies of aluminium extruded lower supporting- and upper shielding-gutter-profiles. The lower supporting- and upper shielding-gutter-profiles are configured to be interconnected with each other while holding lower edge portions of roof-insulation-panels between them. For the interconnecting they comprise a co-extruded male and female central connection portion projecting towards each other and configured to snap-fit into each other. For the holding they each have a V- shaped cross-section formed by a pair of opposing upwardly angled co-extruded flanges.

During assembly, the lower supporting-gutter-profile is fixedly connected on top of a gutter of the greenhouse supporting frame construction. Subsequently, sets of roof-insulation- panels get placed with their lower edge portions resting on top of the flanges of the lower supporting-gutter-profile. Then, the upper shielding-gutter-profile gets placed with its flanges resting on top of the lower edge portions of the sets of roof-insulation-panels, while having its connection portion getting pushed into or onto the connection portion of the lower supporting- gutter-profile. After that, screws get screwed through the flanges into the insulation panels, and sealant is used to seal off transitions between the roof-insulation-panels and the flanges of the upper shielding-gutter-profile. Thus, the upper shielding-gutter-profile truly is able to function as a gutter into which rainwater may accumulate and drain away.

NL-2001177 shows an example of such a roof-insulation-panel mounting system.

A disadvantage of the known roof-insulation-panel mounting system is that its functioning leaves to improved, that its assembly requires specific skills and that its assembly is rather laborious and time-consuming.

Due to heat, cold and sunlight, materials of the system shall crimp and expand. This goes particularly for the aluminium extrusion profiles, and may lead to failure of the sealant between the roof-insulation-panels and the aluminium extrusion profiles. This in turn may lead to leakage along the roof-insulation-panel mounting system, which cannot easily be discharged because the lower supporting-gutter-profile covers up the gutter of the greenhouse. During heavy rainfall, pressure of water on the roof-insulation-panels may also lead to water starting to penetrate into the roof-insulation-panel mounting system and from there into the working and storage space.

Furthermore, due to temperature differences between the working and storage spaces and the outside, heat and cold may be transferred from the upper shielding-gutter-profile to the lower supporting-gutter-profile and from there to the gutter of the greenhouse. This may lead to energy loss and shall influence the conditions inside the working and storage space.

Furthermore, this may also lead to problems with condensation water starting to arise inside the working and storage spaces.

Yet another disadvantage is that transportation of the roof-insulation-panel mounting system requires a lot of space which increase transportation costs.

BRIEF DESCRIPTION OF THE INVENTION

The present invention aims to overcome those disadvantages at least partly or to provide a usable alternative. In particular the present invention aims to provide a user-friendly and fool-proof roof-insulation-panel mounting system that can efficiently and economically be used on all kinds of greenhouse supporting frame constructions to locally make saddle-type roofs of roof-insulation-panels thereupon.

According to the present invention this aim is achieved by a roof-insulation-panel mounting system for working and storage spaces of greenhouses, industrial halls, warehouses, or the like, according to claim 1.

This system comprises at least two sets of roof-insulation-panels extending angled upwards in opposing directions, and a roof-insulation-panel supporting construction. The roof- insulation-panel supporting construction comprises an extruded elongate lower supporting- gutter-profile and an extruded elongate upper shielding-gutter profile, both with a longitudinal direction that extends horizontally. The supporting-gutter-profile has a co-extruded elongate upwardly projecting connection portion, and co-extruded elongate supporting flanges configured for supporting lower edge portions of the roof-insulation-panels and configured for connecting with a supporting frame construction. The shielding-gutter-profile has a co- extruded elongate downwardly projecting connection portion, and co-extruded elongate shielding flanges configured for shielding lower top surface portions of the roof-insulation- panels and configured for forming a gutter between them. According to the inventive thought the system is characterized in that the roof-insulation-panel supporting construction further comprises a plastic extruded elongate intermediate coupling-profile with a longitudinal direction that extends horizontally, and that has a co-extruded elongate downwardly projecting connection portion that is complementary with the connection portion of the supporting-gutter-profile, and a co-extruded elongate upwardly projecting connection portion that is complementary with the connection portion of the shielding-gutter-profile.

The addition of the plastic extruded elongate intermediate coupling-profile in between the extruded elongate lower supporting-gutter-profile and elongate upper shielding-gutter profile brings a lot of important advantages in terms of user-friendliness during mounting and improved operability during actual functioning as an insulated roof. The plastic coupling- profile advantageously can be somewhat flexible, and less rigid and stiff than the supporting- and shielding-gutter-profiles, which nowadays mostly are made out of aluminium.

Furthermore, it has now become possible to first strongly push the downwardly projecting connection portion of the coupling-profile into or onto the upwardly projecting connection portion of the supporting-gutter profile. Thereafter, as a separate distinctive step, the shielding-gutter-profile can be strongly pushed with its downwardly projecting connection portion into connection with the upwardly projecting connection portion of the coupling-profile.

This makes it possible for the interconnecting to take place in a much more controlled manner in two distinctive separate steps. The mounting of the entire assembly thus has become easier, quicker and lighter. More importantly it has appeared to also make the connections themselves much more reliable and stronger.

Not only has the inventive mounting system made the placing and mounting of the relative heavy roof-insulation-panels much quicker and easier, it has even made the entire handling process such fool-proof that less specific skills are required.

Another important advantage is that changing outside temperatures now only shall lead to a crimping, expanding or deforming of the upper shielding-gutter profile. The plastic extruded elongate intermediate coupling-profile is well able to act as an isolator. This prevents the extruded elongate lower supporting-gutter-profile to be negatively influenced by those changing outside temperatures. A thermal bridge is no longer present at the gutter transition between the sets of roof-insulation-panels. First of all, this helps to prevent that the extruded elongate lower supporting-gutter-profile also starts to crimp or expand. Second of all, this helps to prevent leakage problems to arise. Third of all, this helps to prevent the forming of condensation underneath the lower supporting-gutter-profile as well as underneath the roof-insulation-panels themselves. This is particularly advantageous because now if a sandwich panel with a metal skin is used as lower surface sheet, this metal skin without any problem can now be laid in direct thermal contact with for example co-extruded aluminium flanges of the elongate lower supporting-gutter-profile.

Furthermore, owing to the plastic extruded elongate intermediate coupling-profile being able to act as thermal isolator, the roof has obtained a high degree of insulation, preventing loss of heat. This helps to save energy and makes it possible to more accurately control the humidity and temperature inside the working and storage space.

The new mounting system now comprises three distinctive main components, that is to say the extruded elongate lower supporting-gutter-profile, the plastic extruded elongate intermediate coupling-profile, and the extruded elongate upper shielding-gutter profile. This makes it possible to package and transport those three main components in a more compact manner. This saves space and costs and is less polluting for the environment.

Finally it is noted that the mounting system can easily be adapted to different thicknesses of roof-insulation-panels by means of using plastic extruded elongate intermediate coupling-profile of differing heights. The gutter-profiles then do not necessarily have to be changed for that.

It is noted that DE-92.07.859 relates to an upper and lower metal profile for holding 5 glass windows between them, where an intermediate plastic spacer profile is used to connect the upper and lower metal profiles with each other at variable spacing. DE-92.07.859 thus does not relate to a gutter construction with opposingly angled roof-insulation-panels, but to a connection system for holding glass windows extending in a same plane. Furthermore, the purpose of the intermediate plastic spacer profile here is to be able to attach different thicknesses of glass windows between the upper and lower metal profiles. No mention is being made of or hint is given to condensation problems or heat loss due to cold bridges between the upper and lower metal profiles.

Furthermore it is noted that DE-297.19.885-U relates to an upper and lower aluminum profile for holding plastic plates between them, where an intermediate plastic spacer profile is used to connect the upper and lower aluminum profiles with each other at variable spacing.

An upper part of the intermediate plastic spacer profile is provided with a screw channel and can be fixedly secured to the upper aluminum profile from the outside with screws. An aluminum cover profile needs to be clicked over the upper aluminum profile so that the screws are covered. DE-297.19.885-U thus does not relate to a gutter construction with opposingly angled roof-insulation-panels, but to a connection system for holding plastic plates extending in a same plane. Furthermore, the purpose of the intermediate plastic spacer profile here is to be able to attach different thicknesses of plastic plates between the upper and lower aluminum profiles. No mention is being made of or hint is given to condensation problems or heat loss due to cold bridges between the upper and lower aluminum profiles.

Further it is noted that BE-1011040 relates to upper and lower aluminum profiles for holding glazed veranda windows with slidable opening and closing options, where an intermediate plastic spacer profile is used to connect the upper and lower aluminum profiles with each other at variable spacing. BE-1011040 thus does not relate to a gutter construction with opposingly angled roof-insulation-panels, but to a connection system for holding glazed veranda windows extending in a same plane. Furthermore, the purpose of the intermediate plastic spacer profile here is to be able to attach different thicknesses of glazed veranda windows between the upper and lower aluminum profiles. No mention is being made of or hint is given to condensation problems or heat loss due to cold bridges between the upper and lower aluminum profiles. Screws are even provided that extend from bottom to top straight through the intermediate plastic spacer profile and the upper and lower aluminum profiles to fixedly connect them with each other. Those screws form cold bridges between the upper and lower aluminum profiles, leading to condensation problems and heat loss.

Even further it is noted that DE-85.10.255-U relates to upper and lower metal profiles for holding overhanging roof plates, where an intermediate spacer profile is used to connect the upper and lower metal profiles with each other at variable spacing. DE-85.10.255-U thus does not relate to a gutter construction with opposingly angled roof-insulation-panels, but to a connection system for holding overhanging roof plates extending in a same plane.

Furthermore, the purpose of the intermediate spacer profile here is to be able to attach different thicknesses of overhanging roof plates between the upper and lower metal profiles.

No mention is being made of or hint is given to condensation problems or heat loss due to cold bridges between the upper and lower aluminum profiles. It is even mentioned that the intermediate spacer profile can be manufactured from light metal. Such a metal intermediate spacer profile would form a cold bridge between the upper and lower aluminum profiles, leading to condensation problems and heat loss.

In a preferred embodiment according to the present invention the connection portions of the gutter-profiles may each comprise a set of co-extruded elongate spaced apart side walls that together delimit an elongate female clamping space with an insertion slit, and wherein the connection portions of the plastic coupling-profile then each may comprise a co- extruded complementary elongate male insertion part. The plastic co-extruded complementary elongate male insertion parts preferably are configured to fit clamping in between the sets of side walls. The plastic co-extruded complementary elongate male insertion parts preferably are made slightly oversized relative to their corresponding elongate female clamping space. This makes a well controllable quick and strong connecting possible of the plastic intermediate coupling-profile with the more rigid lower supporting-gutter-profile, and of the more rigid upper shielding-gutter-profile with the plastic intermediate coupling- profile. The connecting can be done on location, that is to say starting with a mounting of the lower supporting-gutter-profile on top of a supporting frame construction. The interconnecting of the three profiles then can take place due to the plastic co-extruded elongate male insertion parts being forced in the vertical direction into the elongate female clamping space and come to lie with a force fit in between their sets of side walls of the gutter-profiles.

In addition thereto the male insertion parts preferably may delimit co-extruded elongate hollow chambers. The chambers make it possible that the walls of the plastic male insertion parts may be elastically deformed inwards at the positions of the chambers during the forced insertion. Furthermore the chambers save in weight and plastic material, and help to obtain a uniform wall thickness for the coupling-profile.

In addition thereto or in the alternative the spaced apart side walls delimiting the elongate female clamping spaces can be provided with co-extruded sideways inwardly projecting elongate gripping ridges. This increases the clamping force with which the plastic co-extruded complementary elongate male insertion parts are held inside the female clamping spaces.

Those gripping ridges then advantageously on the one side wall can be provided staggered relative to the gripping ridges on the opposing side wall. Thus it can advantageously be guaranteed that an optimal grip is provided despite tolerance differences that may occur in the gutter- and coupling profiles during manufacturing or use.

In addition thereto or in the alternative the male insertion parts can be provided with co-extruded ridges/grooves. This may further strengthen the connections due to some of the gripping ridges getting to lie inside ridges/grooves.

In a preferred further or alternative embodiment the upper complementary connection portions of the shielding-gutter-profile and coupling-profile may have smaller cross-sectional widths than the lower complementary connection portions of the supporting-gutter-profile and coupling-profile. Thus advantageously the lower connection portion of the shielding-gutter- profile is able to provide a relative wide mounting space for connection elements, like bolts, to be placed therethrough for connection with a lower supporting frame construction. Those connection elements then do not stand in the way of the subsequent connection to be made with the lower connection portion of the elongate plastic coupling profile. The more slender upper connection portions then may have a tighter fit into each other.

In a preferred embodiment the plastic coupling-profile may comprise a co-extruded elongate bridge portion that extends in between its co-extruded elongate lower and upper connection portions. This plastic bridge portion is able to cover an interspacing between the upper shielding-gutter-profile and the lower supporting-gutter-profile in their assembled positions. Depending on a particular thickness of roof-insulation-panels that are to be used, it has become possible to extrude a coupling profile with same upper and lower connection portions and of which only the bridge portion needs to be designed with a height that is complementary to the interspacing to be bridged. Furthermore the plastic bridge portion helps to increase the thermal isolation function of the coupling-profile, and helps to add some torsional or bending flexibility along the longitudinal direction of the coupling-profile. This makes it possible for the roof-insulation-panel mounting system to more easily deal with inside and outside temperature differences, due to which the outer shielding-gutter-profile might crimp, expand, deform in another degree or manner than the inner supporting-gutter- profile.

In particular the bridge portion then may comprises one or more co-extruded elongate intermediate hollow chambers. Those chambers also help to save in weight and plastic material, and help to obtain a uniform wall thickness for the coupling-profile.

In addition thereto the bridge portion may have a larger cross-sectional width than the lower and upper connection portions of the coupling-profile. This prevents the upper and lower connection portions to get inserted into their complementary connection portions of the gutter-profiles too far by forming abutment surfaces.

In a preferred embodiment the coupling-profile may comprise co-extruded elongate impact surfaces that extend horizontally at opposing sides sideways below of its upper connection portion. Those impact surfaces advantageously can be used by a worker to place a hitting tool against, like a slitted block that fits over the upper connection portion, in order to be able to hammer the coupling-profile with its lower connection portion into or onto the supporting-gutter-profile’s connection portion.

In a preferred embodiment the shielding and/or supporting flanges may extend angled upwards in opposing directions, and in particular may be fixedly connected via screws to the roof-insulation-panels. This adds to the strength of the assembly. Thus advantageously a storm-resistant supporting and shielding connection can be obtained between the roof- insulation-panels and the gutter-profiles, without any thermal bridges having to be formed inside the mounting assembly.

In a preferred embodiment lower sides of outer edge parts of the shielding flanges can be equipped with elongate rubber sealing strips. Those sealing strips, that for example are made of EPDM, can be pre-adhered to the upper shielding-gutter-profile’s shielding flanges.

This has the advantage that no sealant needs to be applied by workers. Immediately when the upper shielding-gutter-profile has been mounted on top of the roof-insulation-panels, an automatic seal is obtained. With this the clamp fitting connections between the respective connection portions of the plastic coupling-profile, may help to strongly pull the upper shielding flanges with their sealing strips against the roof-insulation-panels. This makes the sealing strong and reliable, makes the mounting assembly fully leakproof, and also makes it possible to assemble and mount the roof-insulation-panels and gutter-profiles under more extreme conditions in rough environments at relative low or high temperatures. Furthermore,

the sealing strips then can be shielded of against direct sunlight, which increases their lifespan.

Further preferred embodiments of the invention are stated in the dependent subclaims.

The invention also relates to a method for assembling the roof-insulation-panel mounting system.

DETAILED DESCRIPTION OF THE DRAWINGS

The invention shall now be explained in more detail below by means of describing some exemplary embodiments in a non-limiting way with reference to the accompanying drawings, in which: - Fig. 1a and 1b show an exploded perspective and front view of a first embodiment of the roof-insulation-panel mounting system according to the invention; - Fig. 2a and 2b show an assembled front and enlarged partial view of the first embodiment; - Fig. 3a, 3b and 3c show a perspective, front and enlarged partial view of the first embodiment connected with a supporting frame construction of a greenhouse; - Fig. 4 shows a cross-sectional view of the first embodiment connected with another type of gutter of a supporting frame construction of a greenhouse; and - Fig. 5a, 5b and 5c show the views of fig. 4 for differing thicknesses of roof-insulation-panels and connected to other types of gutters.

In fig. 1 and 2 the roof-insulation-panel mounting system comprises a supporting- gutter-profile that has been given the reference numeral 1. The supporting-gutter-profile 1 is formed by an elongate profile that has been extruded out of aluminium. It has an integral co- extruded elongate upwardly projecting connection portion 1a that is formed by two co- extruded elongate vertically upwardly projecting side walls that together delimit an upwardly open elongate female clamping space.

The spaced apart set of side walls are provided with co-extruded sideways inwardly projecting elongate gripping ridges. See fig. 2b. The gripping ridges on the left side wall are provided staggered half a pitch relative to the gripping ridges on the right side wall. With this it is meant that the individual ridges on the respective opposing side walls do not lie at same horizontal levels. Instead each ridge on the one side wall lies substantially opposite a groove in its opposing side wall.

The supporting-gutter-profile 1 further comprises two integral co-extruded elongate supporting flanges 1b that extend in a V-shape under angles a in opposing sideways angled upwards orientations.

Close to transitions with their upwardly projecting connection portion 1a, the supporting flanges 1b are provided with upwardly projecting elongate ribs 1c.

The roof-insulation-panel mounting system further comprises a coupling-profile that has been given the reference numeral 2. The coupling-profile 2 is formed by an elongate profile that has been extruded out of plastic. It has an integral co-extruded elongate downwardly projecting connection portion 2a that forms a lower male insertion part. The lower male insertion part encloses a hollow chamber that is delimited sideways by two co-extruded elongate vertically upwardly projecting side walls. It furthermore has an integral co-extruded elongate upwardly projecting connection portion that forms an upper male insertion part. The upper male insertion part encloses a hollow chamber that is delimited sideways by two co- extruded elongate vertically upwardly projecting side walls.

As can be seen in fig. 1a, the lower and upper male insertion parts are provided with co-extruded ridges/grooves.

The lower male insertion part is dimensioned slightly oversized relative to the female clamping space of the supporting-gutter-profile 1, such that it can only be inserted therein by means of force causing the plastic male insertion part to elastically deform inwards into its hollow chamber.

The coupling-profile 2 further comprises an integral co-extruded elongate bridge portion 2c in between its connection portions 2a and 2b. The bridge portion 2c also encloses a hollow chamber.

The relative slender upwardly projecting connection portion 2b has a width xb that is about twice as small as a width xa of the relative thick downwardly projecting connection portion 2a. The even thicker bridge portion 2c has a width xc that is thicker than both the widths xa and xb of the lower and upper connection portions 2a and 2b.

The coupling-profile 2 comprises co-extruded elongate impact surfaces 2d that extend horizontally at opposing sides sideways below of its upper connection portion 2b. Those impact surfaces 2d here are formed by upper wall portions of the bridge portion 2c.

The roof-insulation-panel mounting system further comprises two sets of thick plate- shaped roof-insulation-panels 3.

Finally the roof-insulation-panel mounting system comprises a shielding-gutter-profile that has been given the reference numeral 4. The shielding-gutter-profile 4 is formed by an elongate profile that has been extruded out of aluminium. It has an integral co-extruded elongate downwardly projecting connection portion 4a that is formed by two co-extruded elongate vertically downwardly projecting side walls that together delimit a downwardly open elongate female clamping space.

The spaced apart set of side walls are also provided with staggered sets of co- extruded sideways inwardly projecting elongate gripping ridges.

The female clamping space of the shielding-gutter-profile 4 is dimensioned slightly undersized relative to the upper male insertion part, such that it can only be pushed over it by means of force causing the plastic upper male insertion part to elastically deform inwards into its hollow chamber.

The shielding-gutter-profile 4 further comprises two integral co-extruded elongate shielding flanges 4b that extend in a V-shape under angles B in opposing sideways angled upwards orientations. The angles B under which the shielding flanges 4b extend are a few degrees smaller than the angles a under which the supporting flanges 1b extend.

Close to transitions with their downwardly projecting connection portion 4a, the shielding flanges 4b are provided with elongate grooves 4c. Those give some flexibility to the shielding flanges 4 during assembly.

Elongate rubber sealing strips 5 are adhered by means of an adhesive tape/layer underneath outer edge parts of the shielding flanges 4b.

In fig. 2a and 2b an assembled mounting state is shown. It can be seen there that the roof-insulation-panels 3 lie with a lower surface sheet on top of the supporting flanges 1b while being delimited to further slide downwards by the ribs 1d.

Furthermore it can be seen there that the rubber sealing strips 5 lie firmly compressed against an upper surface sheet of the roof-insulation-panels 3. This is obtained owing to the shielding flanges 4b being forced to flex somewhat upwards due to the connection portions of the respective profiles being pushed all the way down into each other.

In fig. 3a and 3b a supporting frame construction 30 of a Venlo-type greenhouse is shown. The supporting frame construction 30 comprises vertical uprights 31 and horizontal beams 32 extending in between their upper ends. Gutters 33 are provided that extend in between the beams 32.

The enlarged view of fig. 3c shows that roof-insulation-panel mounting systems rest with their supporting-gutter-profiles 1 on top of those gutters 33. The roof-insulation panels 3 together form a double saddle-type roof.

In fig. 4 another type of gutter 43 is shown. It can also be seen that screws 44 are used to fixedly connect the supporting-gutter-profile 1 on top of this gutters 43. Those screws 44 extend through holes in the bottom wall of the female clamping space of the supporting- gutter-profile 1 and are screwed into an upper wall of the gutter 43.

Furthermore it can be seen here that screws 45, 46 are used to fixedly connect the supporting flanges 1b respectively shielding flanges 4b with the roof-insulation-panels 3.

Those screws 45, 46 extend through holes in the flanges 1b and 4b and are screwed into the steel kins 3a, 3c of the sandwich panels.

The roof-insulation-panels 3 here are formed by sandwich panels with a lower steel skin 3a, an insulation core 3b and an upper steel skin 3c.

The assembling of the roof-insulation-panel mounting system now may comprise the following steps: - In a first step the aluminium extruded elongate lower supporting-gutter-profile 1 is placed upon the gutter 43 and fixedly connected therewith by means of the screws 44. - In a second step the lower male insertion part of the plastic extruded elongate intermediate coupling-profile 2 is gradually hammered over its entire length into the upwardly open female clamping space of the upwardly projecting connection portion 1a of the supporting-gutter- profile 1. - In a third step the roof-insulation-panels 3 are placed with their lower edge portions on the co-extruded elongate supporting flanges 1b; - In a fourth step the downwardly open female clamping space of the downwardly projecting connection portion 4a of the shielding-gutter-profile 4 is gradually hammered over its entire length over the upper male insertion part of the plastic extruded elongate intermediate coupling-profile 2; - In afifth step the screws 45, 46 are screwed through the flanges 1b, 4b into the steel skins 3a, 3c of the roof-insulation-panels 3.

As an example the thickness of the roof-insulation-panels in fig. 4 is 40 mm. In fig. 5a, 5b and 5c this thickness increases to 60 mm, 80 mm respectively 100 mm.

In fig 5a it is shown that a same type of coupling-profile 2 is used as in fig. 1-4, that is to say one with a bridge portion that encloses merely one hollow chamber. In order to be able to span the increasing thickness, a different version of the upper shielding-gutter-profile 4 is used, namely one which has been extruded with a relative long downwardly projecting connection portion 4a.

In fig 5b it is shown that a same type of upper shielding-gutter-profile 4 is used as in fig. 1-4, that is to say one with a relative short downwardly projecting connection portion 4a. In order to be able to span the increasing thickness, a different version of the coupling-profile 2 is used, namely one which has been extruded with a relative long bridge portion 2c, that here encloses three hollow chambers.

In fig 5¢ it is shown that in order to be able to span the increasing thickness, the different version of the upper shielding-gutter-profile 4 is used, namely the one which has been extruded with the relative long downwardly projecting connection portion 4a, as well as the different version of the coupling-profile 2 is used, namely the one which has been extruded with the relative long bridge portion 2c, that here encloses three hollow chambers.

If desired this can further be expanded to even thicker roof-insulation-panels.

Besides the shown and described embodiments, numerous variants are possible. For example the dimensions and shapes of the various parts can be altered. Also it is possible to make combinations between advantageous aspects of the shown embodiments. Instead of using sandwich panels other kinds of roof-insulation-panels can be used. All kinds of other materials can be used for making the gutter-profiles than the mentioned aluminium.

Preferably however they are at least made of metal.

It should be understood that various changes and modifications to the presently preferred embodiments can be made without departing from the scope of the invention, and therefore will be apparent to those skilled in the art. It is therefore intended that such changes and modifications be covered by the appended claims.
