Definitions
- This invention relates to a fastening strip for fastening a plastic sheet material to the top surface of a layer of a bituminous material, said fastening strip comprising a strip of a fibrous sheet material, one side of said fibrous sheet material being coated with a layer of a binder compatible with the plastic sheet material.
- a prior art technique for repairing a worn bituminous roof covering comprises applying one or more additional layers of a roofing felt to the top surface of the roof covering.
- the mechanical fastening means are not capable of preventing the plastic film from being torn away from the roof in case strong winds create a strong suction above the roof covering unless a large number of fastening means is employed.
- roof covering supports are not suitable for mechanical fastening.
- the support may comprise zones which do not offer a sufficient strength for securing a safe attachment of mechanical fastening means.
- bituminous roof felt known from this Danish patent publication which corresponds to EP-A-0 006 189, is for use as a material to cover the full roof surface, but not a fastening strip for fastening another sheet material onto the top surface of an existing layer of a bituminous material.
- the known material is not for fastening a plastic sheet material onto such a surface.
- the metal foil is located on the upper side of the fibrous material in correspondance to its intended use, which is to prevent fire to damage the fibrous material, whereas both the outer sides being coated with bituminous layers are not compatible for binding with a plastic sheet material, as it is intended in the present invention.
- a roof covering material comprising a bituminous layer having incorporated therein two reinforcement layers, i.e. a textile layer and a thin metallic sheet, the bituminous layer being coated with mineral granules.
- a roofing sheet material which is comprised of two bituminous layers having incorporated therebetween a fibrous layer and which is further comprising a layer of an ethylene copolymer and bitumen material (ECB) which is attached to the bituminous layer over its full surface by means of a binder or by welding.
- EBC ethylene copolymer and bitumen material
- this material is not a fastening strip for fastening another sheet material to the roof surface, as it is intended in the present invention.
- the object of the invention is to provide a fastening strip of the above mentioned type which provides a safe continuous bond between a plastic sheet material and a layer of a bituminous material in particular a bituminous roof covering in need of a new weather resistant surface layer.
- the fastening strip of the invention which is characterized in that the side of the strip which is opposite to the plastic compatible binder layer is covered by a metal foil, the free surface of the metal foil being coated with a layer of heat activatable bituminous binder, said heat activatable binder layer being optionally covered by a protective sheet material.
- the fastening strips of the invention present the advantage that they are useful for securing the plastic sheet material to the vertical surfaces along the perimeter of the roof and around skylights.
- the metal foil of the fastening strip of the invention is preferably an aluminium foil and the thickness of the metal foil is conveniently between 3 and 150 ⁇ m.
- the metal foil prevents the softener, if any, present in the plastic film from migrating towards the bituminous binder and to form a harmful separating layer.
- the metal foil and the fibrous layer also serve to protect the binder layer and optionally the plastic sheet material against thermal decompostion or softening when the heat activatable binder is heated during the application of the fastening means of the bituminous surface.
- the strips are attached to the surface of the plastic sheet material to be fastened to the bituminous layer.
- the heat activatable binder on the free surface of the fastening strip is heated to a sufficiently high temperature to ensure that the fastening strip after being forced into contact with the bituminous layer adheres thereto.
- the heating may be effected in a manner which is well known per se by means of a gas burner using liquified gas as fuel.
- the fibrous layer also serves to reinforce the fastening strips.
- the fibrous layer preferably consists of polyester fibres and the weight is preferably between 50 and 500 and more preferably between 150 and 350 g/m2.
- Other types of fibrous layers e.g. a fibrous layer made from glass fibres are also suitable.
- composition of the binder capable of binding to the plastic sheet material depends on the type of the plastic sheet material to be fastened to the bituminous layer.
- the binder When using a PVC sheet material the binder preferably consists of a PVC layer, which may be prepared from a PVC plastisol, i.e. a dispersion of PVC particles and optionally a pigment, a stabilizer, etc. in an oily liquid phase containing oil, softener etc.
- a PVC plastisol i.e. a dispersion of PVC particles and optionally a pigment, a stabilizer, etc. in an oily liquid phase containing oil, softener etc.
- a layer of this type is preferably prepared by impregnating one side of the fibrous layer with the plastisol and subsequently heating the layer thus formed to a temperature of about 180°C to cure the layer. The procedure is repeated until the desired thickness of the layer has been obtained.
- the invention also relates to a roof covering comprising a layer of a bituminous material and a plastic sheet material fastened to the top surface of the layer of bituminous material by means of the fastening strips described above.
- the fastening strip illustrated in the drawing comprises a fibrous layer 1, e.g. a layer of polyester fibres and a metal foil 2 such as an aluminium foil.
- the top surface of the fibrous layer 1 is coated with a binder layer 3, e.g. in the form of a cured layer of PVC plastisol.
- the free surface of the metal foil 2 is coated with a layer 4 of bitumen.
- a strip (width 15 cm) consisting of a polyester felt of a weight of 200 g/m2 and an aluminium foil of a weight of 50 g/m2 was prepared as described in the example of DK patent publication No. 147.979.
- a layer of PVC plastisol was applied to the top surface of the strip thus formed in an amount of 500 g/m2.
- the strip was then passed through a tunnel furnace so as to heat the plastisol layer to a temperature of about 180°C and to cure the PVC. Additional layers of PVC plastisol were applied and follwing the application of each layer the layer was cured as described above.
- the final product thus obtained had a weight of 1400 g/m2.
- a layer of adhesive bitumen was then applied to the non-coated side of the aluminium foil in an amount of 800 g/m2.
- the adhesive bitumen used consisted of bitumen containing 10 % thermoplastic SBS rubber and 6 % resin.
- the layer was covered with a polyethylene film of a thickness of 10 ⁇ m.
- Fastening strips thus prepared were used for fastening a PVC film to the top surface of a bituminous roof covering.
- the strips were fastened to the roof covering by heating the layer of adhesive bitumen to its melting point using a gas burner. Concurrently with the heating of the adhesive bitumen the thin polyethylene film was burned off. The strips were placed parallel to each other and with a spacing of about 200 cm.
- PVC sheets having a width of about 2 m and a thickness of about 1,5 mm and being reinforced with polyester tissue having a weight of 10 g/m2 were unrolled over the strips.
- the PVC sheet was placed in such a manner that its centre line was located above and parallel with a fastening strip.
- the PVC sheet was then connected to the strips thus applied by swell welding using tetrahydrofuran as solvent.
