CertainTeed CedarBoards Insulated Siding

CedarBoards takes vinyl siding to the next level by bonding a contoured EPS foam backing to each panel. This foam fills the gap between the siding and your wall sheathing - a gap that in standard vinyl allows convective air loops that waste energy. The result is an R-3.5 insulation value that measurably reduces your heating and cooling costs.

The foam backing also provides two other benefits that standard vinyl can't match: impact resistance (the foam absorbs impacts from hail and debris that would dent standard vinyl) and noise reduction (the foam dampens exterior sound). The wind rating jumps to 200+ mph because the foam eliminates panel flex. For Northern Virginia homes, CedarBoards is the sweet spot between vinyl and fiber cement.
