Description
VAPOR AND RADIANT BARRIER
FIELD OF THE INVENTION
The present invention relates to a vapor and radiant barrier membrane used in insulation applications in the construction industry. More specifically, the vapor and radiant barrier membrane of the present invention relates to a laminate of an aluminum substrate and polyethylene layers.
BACKGROUND OF THE INVENTION
Vapor barriers have proven to be an effective means for improving the insulation properties of the walls of a building.
Many vapor barriers of the prior art use, alone or in combination, materials such as paper, metal foils, or specialized Kraft paper. Examples of such vapor barrier are shown in US patents nos. 4,625,486 and 5,750,225.
The choice of the materials used is often guided so as to provide a vapor barrier with specific desired physical characteristics. The most common characteristics sought-after are an improved rigidity, an improved surface abrasion resistance and an improved tensile strength. However, in general, the vapor barriers of the prior art, because of their construction, have been more expensive than desired.
There is thus still a need for an improved cost-effective vapor barrier.
SUMMARY OF THE INVENTION
An object of the present invention is to propose a vapor barrier that will satisfy the above-mentioned need.
Another object is to propose a cost-effective vapor and radiant barrier membrane having heat reflectivity and vapor protection capacities as well as high tensile strength and rigidity.
In accordance with the present invention, these objects are achieved with a vapor and radiant barrier membrane for covering a wall surface. The membrane comprises a facing layer which contains a radiant material, and a backing layer laminated to the facing layer. The backing layer is made of polyethylene and has a thickness that limits vapor permeability.
The present invention also provides a wall structure which comprises a wall body with an inner and an outer face, and a vapor and radiant barrier membrane as described above which covers either the inner face or the outer face of the wall body.
The vapor and radiant barrier membrane according to the present invention is lighter and thinner than the usual vapor barrier of the prior art and still provides a greater tensile strength, an improved rigidity and a smoother outer surface for better abrasion resistance.

The polyethylene of the first sheet (16) is preferably a virgin low density polyethylene whereas the second sheet (18) of the backing layer (14) is preferably a combination of virgin low density and linear low density polyethylene.
The facing layer (12) preferably consists of a radiant aluminum foil of about 0.275 mil thick, the first sheet of polyethylene (16) of the backing layer (14) preferably has a thickness of about 0.5 mil and the second sheet of polyethylene (18) of the backing layer (14) preferably has a thickness of about 2.5 mils.
Referring now to Figure 2, the present invention also relates to a wall structure (20) comprising a wall body (22) with an inner face (24) and an outer face (26) and a vapor and radiant barrier membrane (20) according to the present invention. The latter (20) covers either one of the inner face (24) and outer face (26) of the wall body (22) . The inner face '(24) and the outer face (26) are both preferably and respectively covered with an interior finish (30) such as plastered sheeting (for example Gyprox*) and an exterior finish (31) made of a brick wall, a wood plank, plastic or aluminum, as apparent to a person in the art. It will be

understood that the wall structure (20) refers to any type of wall that is commonly known to a person skilled in the field of construction, for example, it could be a concrete wall, a wall constructed with wood or metal studs or any other type of construction.
In a preferred aspect, the membrane (10) is sandwiched between the inner face (24) and the interior finish (30) . A plurality of spaced-apart holding strips (28) are used to secure the membrane (10) to the inner face (24) of the wall body (22) . The interior finish (30) is then secured to the holding strips (28) and covers the membrane (10) . Air spaces
(32) are defined between the membrane (10) and the interior finish (30) so as to provide an efficient factor R. An efficient factor R can be obtained with an air space of H of an inch.
Figure 3 is a flow sheet showing the steps of a process for a vapor and radiant barrier membrane (10) according to the present invention. Other embodiments and variations thereof within the scope or teaching of this invention will be apparent to one skilled in the art. In the particular embodiment illustrated in Figure 3, the aluminum foil (12) is fed from roll 50 along with the first sheet of polyethylene (16) from roll 52 and the second sheet of polyethylene (18) from roll 54. Then, the aluminum foil (12), the first and the second sheets (14, 16) are all fed to laminating rolls 56 and 58 which press and laminate the foil (12) and the polyethylene sheets (14, 16) together so as to create the vapor and radiant barrier membrane (10) of the present invention which is finally wrapped on the roll 60.
The first sheet of polyethylene (16) is preferably provided in a semi-fluid form which is preferably obtained by heating
the first sheet (16) at about 600°F. The semi-fluid polyethylene of the first sheet (16) acts as an adhesive which falls between the aluminum foil (12) and the second sheet of polyethylene (18) . The first (16) and the second (18) sheets of polyethylene are then bonded or melted altogether so as to form the backing layer (14). The sandwich construction is preferably the result of a mechanical and heated laminated bond between the facing layer (12) and the backing layer (14) of the membrane (10) of the present invention.
