FLEXIBLE WEATHER RESISTANT BUILDING WRAP
Abstract
A method of enveloping a building in a weather resistant wrap is
disclosed. A weather resistant building or house wrap is disclosed.
The wrap is of a thin flexible web or sheet of material having
multiple layers. The layers include a metallized polymeric layer
(e.g. polyester metallized with aluminum) adhered to a closed cell
foam layer. The metallized portion preferably faces the adhesive
layer. The polymeric layer is an outside surface layer as is the
closed cell foam layer.

BACKGROUND OF THE INVENTION
[0006] 1. Field of the Invention
[0007] The present invention relates to the construction of
buildings or homes, and more particularly, to a weather resistant
barrier or "wrap" for buildings that combats water, moisture, or
air infiltration, important for those structures that are
constructed of a wooden or like framing.
[0008] 2. General Background of the Invention
[0009] Moisture can be one of the worst enemies of a home or
building. Water or moisture or humid air infiltration if allowed to
penetrate behind siding or brick can saturate the wood of a
building structure, thereby creating an environment that encourages
mildew or rot.
[0010] A weather resistant barrier has for many years been applied
to the wood studs of buildings and homes in order to resist the
moisture or water generated by weather. Such material is typically
flexible and in a film or sheet form. Typically, this weather
resistant barrier or "house wrap" is applied to the wooden stud
frame before the application of a final siding or veneer (e.g.
brick, metal, painted wood). Many such "wrap" products are
commercially available such as, for example: Dupont Tyvek.RTM.,
Typar.RTM. Housewrap (www.typarhousewrap.com), and Barricade.RTM.
building wrap (www.ludlowcp.com).

foam layer or carbonized foam layer adhered to it using a selected
layer of adhesive.
[0014] This sheet of flexible material is provided with a matrix of
small openings that are preferably spaced over the sheet of
material, each opening being for example between about 0.1 and 1.5
millimeters in diameter. The openings are preferably spaced apart a
distance of between about 0.25'' and 1.5'' (0.64 and 3.8 cm).
[0015] In the preferred embodiment, the polyester layer is
metalized on a surface area of the polyester layer that is next to
the adhesive layer.
[0016] In the preferred embodiment, the layer of adhesive is a
thermoplastic adhesive layer.

foam layer. The foam layer for example can be a polyethylene foam
layer or a carbon foam layer or a carbonized foam layer.
[0018] The openings are preferably between about 0.3 and 0.7
millimeters in diameter, and preferably about 0.5 millimeters in
diameter.
[0019] The layer that is metalized is preferably aluminum.
[0020] The aluminum metalized layer is preferably an aluminum
having an optical density of at least about 2.7, and more
preferably at least about 4.0.
[0021] The metalized layer preferably has an emissivity of no more
than about 0.03.
[0022] The present invention provides a method of wrapping a framed
building (i.e. wooden stud frame) that includes at least partially
enveloping the studs of the building with a flexible sheet of
material, the sheet being a multilayer sheet that includes an inner
layer of foam, an outer layer of polyester having inner and outer
surfaces, the inner surface being a metalized surface.
[0023] An adhesive layer is placed in between the foam layer and
the outer layer of polyester wherein the adhesive layer contacts
the metalized surface.
[0024] The method includes perforating the sheet of material and
then securing the perforated sheet to the wooden framing (e.g.

DETAILED DESCRIPTION OF THE INVENTION
[0031] FIGS. 1-5 show the preferred embodiment of the apparatus of
the present invention designated generally by the number 10 in
FIGS. 1-5.
[0032] Flexible house wrap 10 is preferably provided in roll 11
form wherein a web or sheet 12 of material is wound upon the roll
11. The web or sheet 12 has spaced apart generally parallel edges
13, 14 and end portions such as the end 15 shown in FIG. 1.
[0033] The web or sheet of material 12 is preferably perforated
generally in a matrix pattern as shown in FIG. 2. The perforations
16 are preferably spaced apart a dimension designated by arrows 17
in FIG. 2. Additionally, a spacing indicated by arrows 18 is
provided as a minimal spacing between edge 13, edge 14 or end 15
and a perforation 16 as shown in FIG. 2.
[0034] In FIG. 3, the web or sheet of material 12 is shown in
section. The sectional view shown of FIG. 3 reveals a multilayered
web or sheet 12. The layers of the web or sheet 12 include an upper
layer 19 which is a polymeric layer. The polymeric layer 19 can for
example be a polyester layer.
[0035] A metal foil layer 20 is preferably a metalized layer that
is applied to the polymeric layer 19. An adhesive 21 layer joins
the polymeric metalized layer 19, 20 to a foam layer 22, preferably
a closed cell foam such as polyethylene foam.
[0036] The foam layer can be a carbon or carbonized foam layer.
Examples of carbon foam or carbonized foam can be found in U.S.
Pat. No. 3,922,334 entitled "Foam Carbonization and Resulting Foam
Structures"; U.S. Pat. No. 5,888,469 entitled "Method of Making a
Carbon Foam Material and Resultant Product"; U.S. Pat. No.
6,033,506 entitled "Process for Making Carbon Foam"; U.S. Pat. Nos.
6,183,854 and 6,346,226, each entitled "Method of Making a
Reinforced Carbon Foam Material and Related Product," each hereby
incorporated herein by reference.
[0037] In FIGS. 4 and 5, a building frame 23 is shown, and
particularly wall 24 and roof 25 frame portions. The wall 23 can be
formed using wooden studs such as the horizontal 26 beams and the
vertical 27 beams in FIG. 4.
[0038] Roof 25 can be formed of a plurality of beams such as the
beam 28 that extends horizontally at the apex of the roof 25 and
the diagonally extending beams 29.
[0039] In FIG. 4, the web 12 of material can be applied to the
outer surface of the wall 24. In FIG. 5, the web 12 of the material
is preferably attached to the underside of the beams 28, 29.
[0040] To the extent not inconsistent with information in the
present specification, thicknesses of materials, types of
materials, and amounts of adhesive can be as in published
application no. US 2005/0058790 A1, published 17 Mar. 2005 for

layer 19 of the present application corresponding to layer 2 of the
published application, layer 20 of the present application
corresponding to layer 1 of the published application, layer 21 of
the present application corresponding to layer 5 of the published
application, and layer 22 of the present application corresponding
to layer 4 of the published application. Sheeting 12 of the present
invention can be made in the manner that metallized heat resistant
material 6 is made in the published application.
[0041] The total thickness of the sheeting 12 of the present
invention can be, for example, 0.1-1.5 mm, preferably 0.3-1.3 mm,
and more preferably 0.8-1.0 mm.

and most preferably greater than 4.0.
[0043] The emissivity is preferably less than 0.06, more preferably
less than 0.04, and even more preferably less than 0.03.
[0044] The diameter of the perforations 16 is preferably around
0.1-1.5 mm, more preferably around 0.3-0.7 mm, and even more
preferably around 0.4-0.6 mm. The diameter can be, for example,
around 0.5 mm.
[0045] The spacing 17 between perforations 16 can be 1/16''-1.5''
(0.16-3.8 cm), preferably 1/8''-1.0'' (0.32-2.5 cm), more
preferably 3/16''-7/8'' (0.48-2.2 cm), and for example 1/4'' (0.64
