Abstract
The invention refers to a base profile for the implementation of insulation facades. A base profile consists of an internal element and external element, which are firmly joined with a connecting element. Internal and external elements are primarily acquired through recycling technological procedures, from wood materials or biopolymers. According to this invention, the impact of thermal bridge at the passage going from the plinth of the facade onto the facade surface is reduced to a minimum by using a base profile. The passage from the base of the facade on the facade surface can be emphasized or continuous.
Description
Base profiles for the implementation of contact insulation facades with reduced impact of thermal bridge
Technical field
The invention refers to reducing extreme thermal bridges relating to base profiles of contact insulation facades. Base profiles are used as a finishing line or divide the facade surface from the plinth area. The invention falls within the branch of civil engineering, more specifically contact insulation facades (ETICS - External Thermal Insulation Composite / Compact System or German WDVS - Warme-Damm- Verbund-System), i.e. supporting base profiles of the facade, a plinth or a base of the facade.
Technical problem
When making a passage going from a plinth or a base of the facade onto a facade surface, base profiles are used. Commonly known implementations of base profiles are based on robust materials, which are unfortunately highly thermally conductive, i.e. metal sheet or a highly thermally conductive aluminium, tough artificial or plastic materials, etc. A common characteristic of the said materials is good conductivity, in cases of metal profiles thermal conductivity can be extremely high. Therefore a very powerful thermal bridge is created, which in turn causes a number of problems in cases of modern energy-saving constructions, where the thickness of thermal insulation is often 30 cm and more. In the past this particular detail did not cause trouble from the energy-saving point of view, as heat dissipation over the said thermal bridge was not considerable in terms of total heat loss of the exterior building envelope. However, in cases of low energy-saving constructions or near-zero-energy buildings, the same thermal bridge represents a large part of total heat loss of the construction quantity-wise.
According to this invention, a base profile reduces an impact of a highly problematic thermal bridge occurrence to the smallest possible extent, thus providing an aesthetic installation of the passage going from a plinth or a base of the facade onto a facade
surface; the passage can either run from the surface of a base onto the rest of the facade surface in a visible way, or can run continuously, which means it is concealed.
State of the art
In order to prevent thermal bridges relating to base profiles of contact insulation facades, i.e. at the point where the plinth contacts the facade, certain solutions can be considered. One is an aluminium base profile, which is cut off with an artificial material that is considerably less thermally conductive; the other solution is the base profile, which is fully made from plastic material. Base profiles are metal profiles, ranging in size at around 1 mm or more and profiles from plastic material, only a few mm large. Thermal conductivity of the existing materials, which are currently used for base profiles is therefore bigger than 0.15 W/(m K), which consequently represents considerable part of total thermal loss in cases of low energy-saving constructions or near-zero-energy buildings.
Some cases of certain solutions are presented on the website of the company

Description of a new solution
Said technical problem is solved by using a base profile according to this invention. A base profile consists of the element, connecting it to the wall on one side, i.e. between the facade and the wall, and of the element, which provides a drip edge and a passage from the facade surface onto the plinth surface on the other side, i.e. the exterior part of the facade. Both elements are firmly joined with a connecting element, which is in fact a compact thermal insulation component. This prevents direct thermal contact and therefore prevents thermal bridges. Considering the fact
that a connecting element is a compact thermal insulation component, thermal conductivity of a base profile is considerably smaller than currently known versions. In order to provide good compact quality, strength and rigidity of a base profile described in this invention, a compact insulation material of increased thickness is used, connecting both elements. Thickness of thermal insulation component as a connecting element is primarily ranging from 1 cm to 8 cm in size and even more, if necessary.
The shape of a base profile with all integral elements can have a different form and width so as to adapt to all thicknesses of thermal insulation in the facade and to a plinth or a base of a construction and to different heights. The form of internal 1 element for fixation to the wall can be optional with a basic function of a simple and effective adjustability and fixation to the wall. Likewise, an external 2 element of the facade side can have different forms and its key purpose is providing passage from the facade surface onto a plinth or a base of a construction, by optionally providing the implementation of a drip edge.
The shape of a profile of a connecting element 3 in the base profile system is primarily prismatic, i.e. offering a square cross-section.
The invention is shown on the figure below in detail.
Figure 1 shows an axonometric view of a base profile in order to implement contact insulation facade.
According to this invention, a base profile for the implementation of contact insulation facade consists of an internal element 1 , i.e. an element for fixating to the wall and an exterior element 2, i.e. an element to implement a drip edge and simultaneously a passage from the facade surface onto the surface of the plinth or a base of the facade. Both elements are primarily made of natural recycled wood materials or of biopolymers, or of the materials, acquired via recycling procedures and technological processes, even of the materials of synthetic and metallic composition. An external 2 element and internal 1 element are linked with a connecting element 3, which firmly
joins both elements. A connecting element 3 is made of an effective thermal insulation component, primarily from XPS, EPS, polyurethane and other compact thermal insulation materials, so as to prevent heat transfer to the greatest possible extent.
The internal element 1 is primarily formed as a reverse letter F, whereby legs 1 a and 1 b form a groove 1c, into which a connecting element 3 is fixed or glued; on the lengthened baseline of side 1 d there are designed spots or holes to install the screws in order to fixate an internal element 1 onto the facade and if necessary, the spots, where spacing elements are placed to compensate for the uneven facade walls, which are not shown on the figure. The external element 2 is primarily formed as a letter U, whereby legs 2a and 2b form a groove 2c, onto which a connecting element 3 is fixed or glued; on the slightly lengthened baseline 2d, a basic and finishing roughcast of the facade is attached with a reinforcing mesh. Where there are passages going from the facade onto a plinth with emphasized delay, a lengthened baseline 2d is also designed for simultaneous implementation of a drip edge. A connecting element 3 is primarily formed as a block. The size of the grooves 1c and 2c is the same and is adjusted to the thickness of a connecting element 3.
