BRES leaves room for thorough insulation. In most new construction, exterior walls are 2 X 4. All of our exterior walls are 2 X 6, allowing for insulating to R 19. Ceilings are insulated to R 50 as they see the highest temperature differences in the summer.
Top quality windows and doors with the best insulating properties available are key to a tight, well insulated house. Additionally, all the ductwork in our houses runs within the envelope and thus avoids all the heat loss that duct runs in attics and crawl spaces suffer from.
