Exterior Wall Insulation

Exterior Wall Insulation

Exterior walls are another common area where heat escapes in the winter and heat is absorbed in the summer. To properly insulate and dense pack exterior walls, a small amount of siding is removed and holes are drilled into the side of the house to access stud cavities. A fill tube is then inserted into the cavity and cellulose is packed at a density of 3.5lbs/cubic ft. When insulation is installed at this density it provides a unique air sealing quality. The holes are then plugged and foamed, a vapor barrier is installed over the plug, and the siding is re-installed.
