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.
