Definitions
- the invention relates to the use of a composite film which is composed of a plurality of layered materials.
- the invention relates to the use of a composite film, which is suitable for laminating or cladding of insulating materials, in particular of insulating materials for installation pipes, insulating materials for the sheathing of containers of various kinds, and insulating materials for coating panels.
- Such insulation materials are currently dressed, for example, with aluminum or galvanized steel sheets with a thickness of about 0.6 to 1.00 mm.
- the disadvantage of these thick sheets is their inflexibility. Mechanical damage of the sheets, e.g. Dents, persist in the material in the long run. The material costs are relatively high, even in the processing of such materials, there are problems, in particular due to the high weight.
- Another disadvantage is that the sheets are always retrofitted, e.g. on the construction site, can be applied to the insulation material.
- a composite film For the isolation of insulation materials, a composite film has also been made available which comprises as outer layer a film of polyethylene terephthalate (PET), an inner layer of polypropylene material (PP) and a film of aluminum located between the inner and outer layers.
- PET polyethylene terephthalate
- PP polypropylene material
- This composite film also has the disadvantage of low weathering stability.
- the Austrian utility model AT 7931 U describes a composite film which is made up of a plurality of layered materials, containing at least
- the main or backing layer b) preferably consists essentially of polyvinyl chloride (PVC) rigid films.

- the present invention has as its object to overcome the disadvantages of the prior art and to provide a material which is better suited for application to insulation materials in the outdoor area.
- the composite film defined in claims 1 to 14 is outstandingly suitable for application to an insulating material, e.g. for laminating or cladding of insulating materials, in particular of insulating materials for installation pipes, insulation materials for the sheathing of containers of various kinds, and insulating materials for coating panels, is suitable.
- Glass fabric or glass nonwovens have the great advantage over plastic materials previously used as support layer b) that they are virtually non-combustible and the resulting composite film thus has a lower flammability.
- Materials made of glass fabrics or glass nonwovens are also characterized by a high temperature stability; in the case of burning - in contrast to plastic materials - no or minimal generation of harmful gases can be observed.

- carrier layer b a glass fabric is used which is constructed of glass threads of the type EC 9-68 (an E-glass according to DIN 1249 Part 1 with a yarn count of 68 tex).
- the threads of the glass fabric are preferably interwoven in plain weave.
- the use of twill weave glass fabrics is also possible.
- the glass fabric may be equipped with a conventional finishing, in particular a so-called “weave-lock-fmish”.
- the glass fabric or glass fleece used as backing layer b) may be colored.
- the glass fabric or glass fleece used is white.
- a particularly preferred embodiment of the present invention has as support layer b) a glass fabric of the type 7628 with a basis weight of about 200 g / m 2 , a thickness of about 200 microns, consisting of glass threads of the type EC 9-68 in plain weave and equipped with a "weave lock" finishing.
- the composite film used according to the invention due to the combination of several layers numerous advantages: Due to the outer layer a) the film is resistant to Incidence of light and also weather-resistant. Thus, the outer layer a) also acts as corrosion protection for the layer c).
- the layer a) is preferably a coating, paint or a film and may optionally be colored.
- layer a) may consist essentially of a material selected from the group consisting of silicone-based coatings, acrylic lacquers, nitrocellulose lacquers and films of UV-resistant polyethylene terephthalate and high-pressure polyethylene or mixtures thereof.
- the layer c) serves as a water vapor barrier and thus as further protection for the insulating material, on which the composite foil is applied.
- the layer c) is preferably a metal layer and / or a metallized layer of plastic, in particular an aluminum foil or an aluminum layer applied by vapor deposition.
- the layer b) gives the composite film in particular the necessary strength against mechanical influences.
- the thickness of the carrier layer b) is 40% to 95%, preferably at least 70%, particularly preferably at least 80% of the total thickness of the composite film.
- the thickness of the layer c) may preferably be 5 to 50 ⁇ m, particularly preferably up to 20 ⁇ m, in particular from 9 to 12 ⁇ m.
- the thickness of the layer a) may preferably be 10 to 35 ⁇ m or 5 to 30 g / m 2 .
- the composite film preferably consists essentially of the layers a), b) and c). This is to be understood as meaning that apart from any necessary adhesive layers between the layers a), b) and c), the composite foil has no further material layers.
- the total thickness of a composite film consisting of the layers a), b) and c) is preferably 50 microns to 800 microns.
- the composite film used according to the invention may also have further layers.
- an additional sealing layer or insulating material below the layer b) may be applied a layer of adhesive, which is optionally provided with a peelable film in order to apply the composite film used in the invention to the insulating material can.
- Another possibility is to provide an aluminum layer below the layer b) on the insulating material side.
- the composite film used according to the invention contains at least one further layer e) of thermoplastic material, in particular consisting of a material selected from the group consisting of polypropylene, polyvinyl chloride, high-pressure polyethylene, polyethylene terephthalate and polystyrene or mixtures thereof.
- a composite foil containing such a layer in combination with the use according to the invention of a layer of a glass fabric or a glass fleece has a good restoring force, whereby any e.g. in the assembly of the composite film or the insulating material resulting dents u.a. be compensated again.
- the layer e) is preferably arranged between the layer b) and the layer c).
