Charter Oak Energy Elite wraps a thermal blanket snugly around your home. It delivers up to four times the “R”-value of conventional siding – and can reduce your energy bills as much as 20%.
This premium insulated siding is custom-fitted to your home on site, eliminating the need for gluing or laminating in the manufacturing process. So Charter Oak Energy Elite fits snugly, but the vinyl and insulating layers are free to move and expand, reducing the potential for warping or binding.
