Many of our vinyl siding products are fused to a foam backing material, to create an all-in-one siding and insulation system. It's energy efficient and highly impact resistant with solid support behind the entire siding surface. By adding an additional foam insulation layer, the R-values of exterior walls are increased by R-2.9 to 3.5 depending on the profile, helping to save on heating and cooling costs.
The foam is made from environmentally friendly polystyrene, which has thermal expansion properties nearly identical to vinyl siding, and moderate vapor permeability to allow the siding to breathe. Unlike conventional siding, the foam offers protection against dents and other impact damage, allowing the siding to remain aesthetically pleasing, functional, and lasting. The system provides the thermal insulation benefits of foam sheathing in a format that enhances the appearance and performance of vinyl siding, including sound control properties.
