Abstract

This disclosure relates to an insulative system and materials therefor comprising a polymeric composition disposed at the junctions of the framing and exterior sheathing. In particular, an insulative system and materials therefor comprising a polymeric composition in the form of a sealing structure in contact with both the framing and exterior sheathing of a building are described.

First claim

1 . A building insulation system comprising an elastomeric polymer and a low density fiber insulation product, wherein
the elastomeric polymer is adapted to contact a building to fill and seal gaps, the gaps formed at a location between two or more structural members of a wall, the elastomeric polymer configured to provide means for blocking movement of air through the wall so that air infiltration is diminished by at least about 96% to maximize energy efficiency of the structure, total volatile organic emissions released during curing is minimized, and ASTM E84 flame resistance is better than 25/75.

2 . The building insulation system of claim 1 wherein the elastomeric polymer is configured to have a cross-sectional profile featuring a central ridge having a depth of between about 2 mm and 15 mm.

3 . The building insulation system of claim 1 wherein the elastomeric polymer is configured to have a cross-sectional profile having an area of between about 16 mm 2 and 169 mm 2 .

4 . The building insulation system of claim 1 wherein the elastomeric polymer is configured to have a cross-sectional profile having an area of between about 36 mm 2 and 144 mm 2 .

5 . The building insulation system of claim 1 wherein the elastomeric polymer is configured to have a cross-sectional profile having an area of between about 36 mm 2 and 100 mm 2 .

6 . The building insulation system of claim 2 , wherein the cross-sectional profile includes a tail region that extends onto the two or more structural members according to a diminishing pattern.

7 . The building insulation system of claim 6 , wherein the cross-sectional profile results in a concave surface facing away from the two or more structural members.

8 . The building insulation system of claim 6 , wherein the diminishing pattern extends onto one of the two or more structural members for a distance of between 5 mm and about 80 mm.

9 . The building insulation system of claim 6 , wherein the diminishing pattern extends onto one of the two or more structural members for a distance of between 5 mm and about 45 mm.

10 . The building insulation system of claim 2 , wherein the cross-sectional profile includes an extension that at least partially fills the gap between the two or more structural members.

11 . The building insulation system of claim 1 , wherein the elastomeric polymer comprises by weight about 10% to about 60% of an carboxylic acid containing polymer, about 16% to about 60% of one or more inorganic fillers, and less than about 5% flame retardant.

12 . The building insulation system of claim 11 , wherein the elastomeric polymer comprises by weight
about 10% to about 40% of an acrylic resin, about 20% and 45% water, and about 10% to about 30% calcium carbonate, about 5% to about 10% Kaolin clay about 1% to about 5% titanium dioxide, and less than about 3% flame retardant.

13 . The building insulation system of claim 11 , wherein the elastomeric polymer comprises a dipropylene glycol dibenzoate, a polyvinyl acetate emulsion, and a polymerized rosin.

14 . The building insulation system of claim 11 , wherein the elastomeric polymer has a pH of between about 7.2 and about 10.3.

15 . The building insulation system of claim 11 , wherein the elastomeric polymer has a pH of between about 8.4 and about 9.6.

16 . The building insulation system of claim 11 , wherein total volatile organic emissions released during curing is less than about 0.5 mg/m 3 .

17 . The building insulation system of claim 11 , wherein total volatile organic emissions released during curing is less than about 0.1 mg/m 3 .

18 . The building insulation system of claim 11 , wherein total volatile organic emissions released during curing is between about 0.001 than about 0.01 mg/m 3 .

19 . The building insulation system of claim 11 , wherein the elastomeric polymer has a cured density of between about 0.8 and about 1.8 g/mL.

20 . The building insulation system of claim 11 , wherein the elastomeric polymer has a cured density of between about 1 and about 1.6 g/mL.
