No insulation in walls or attics
Why it happens here
Most homes in the Historic Homes Area were built before insulation was standard. Walls are solid masonry or plaster on brick with no cavity. Attics were left bare. This was normal in 1900 but costs you hundreds every winter.
Our approach
We use injection foam for closed cavities and blown-in cellulose for attics. For solid walls, we add interior foam board with minimal thickness. Our goal is to add R-value without changing the historic character.
