Definitions
- the invention relates to a vapor diffusion-open, waterproof and reflective film for use in vapor barrier, waterproofing and insulating membranes in and on buildings, in particular for use in and with thermal insulation.
- Vapor barrier, waterproofing and insulating membranes are usually used for room-side sealing of roof structures, with a removal of moisture, especially in the form of water vapor, should be achieved from the room side to the roof side, but moisture from the roof side should be inhibited as possible.
- Vapor barrier, waterproofing and insulating membranes protect the thermal insulation against moisture penetration and thus ensure their functionality. Moisture and heat transfer by convection are prevented.
- a combination of a vapor diffusion open, waterproof and heat-reflecting waterproofing membrane is known from German Utility Model DE 20 2004 007 543 Ul.
- the heat-reflecting layer is applied to a foil by means of metal vapor deposition in an embodiment.
- this film is subjected to embossing and perforation.
- the object of the invention is to provide an improved vapor barrier, sealing and insulating sheet in the form of a film.
- the erfindungsgeniäße vapor diffusion-open, waterproof and reflective film consists of at least two layers, wherein a first layer of a vapor diffusion-open and waterproof backing layer and a second layer of a reflective layer of a metal or metal oxide and is characterized in that the reflective layer without interruption directly on the carrier layer is applied.
- any known vapor diffusion open, i. water vapor permeable and waterproof material can be used.
- Such materials are e.g. Polyamides, polyesters, polyurethanes, ethylene vinyl acetates, polyvinyl chlorides, thermoplastic elastomers.
- the water vapor permeability of the carrier layer can be from 5 g / m 2 d to 5000 g / m 2 d.
- the reflectance of the carrier layer is in the lower range of less than 50%.
- the reflective layer which in the case of metal layers preferably consists of aluminum or, in the case of metal oxides, preferably of aluminum oxide, is applied to this carrier layer.
- the application is carried out in particular by vapor deposition according to a conventional method.
- the reflective layer is applied in a thickness such that an optical density of 0.5 to 2.5, preferably 1-1.5, is achieved.
- Density is carried out by density meters, e.g. Theimer DDM3 or X-Rite for transparent specimens or with the Nagy SD 510 gauge for opaque specimens
- the ratio of the water vapor permeability in percent of a film according to the invention for the water vapor permeability of an uncoated carrier layer is from 70% to 95%.
- the water vapor permeability can according to eg according to DIN 52615: "Determination of
- the reflectance of a film according to the invention is greater than or equal to 70%, preferably from 70% to 87%.
- the degree of reflection in percent indicates the ratio of reflected to irradiated energy.
- FIG. 1 shows the course of the reflectance R and the water vapor permeability WDD as a function of the optical density OD of a film according to the invention.
- the carrier layer is a 40 micron thick polyamide film, which is vapor-deposited with aluminum oxide in different optical density.
- the reflectance R increases here with increasing optical density OD of about 20% of the uncoated support layer to about 95% according to the curve ( ⁇ - ⁇ - ⁇ ), wherein a decrease in the water vapor permeability WDD represented by the curve (A-A-A) occurs.
- the film according to the invention can additionally be combined with further reinforcing and / or protective layers.
- nonwovens, fabrics, scrims, foams, lacquers and other functional protective layers are suitable for this purpose.
- the film according to the invention is preferably suitable as an insulation sheet.
- This insulation sheet may consist of one or more layers of the films of the invention.
- the insulation sheet is particularly suitable for use in refrigerated containers, in heat containers, in transport containers, in particular for the shipping, automotive, aerospace industry, in functional textiles and in footwear.
