Challenge

Fogarty's Home Services fixes an uninsulated exterior wall to keep house more comfortable and lower the cost of fuel/electric bills.

Common uninsulated exterior wall problems - Cold, drafty rooms, uncomfortable home, heating and cooling systems run ,uch more and need more service, difficult to keep house at comfortable temperature, higher fuel and electric bills, dry home in winter, more dust/pollen, more humidity in the house in summer when air conditioned.

Many older homes have no insulation in the exterior walls. The problem this causes are obvious. Heat flows from more (inside) to less (outside in winter) right through the walls, and opposite in summer. Nearly all walls leak air, insulated or not, causing drafts. The cold wall surface cools interior air which then sinks and travels across the floor up the warmer interior wall, and across the ceiling back to the exterior wall. This is called "convective loop" and make rooms feel even draftier.

Solution

The results and solution of Fogarty's Home Services fixing the uninsulated exterior walls for a homeowner in South Windsor, CT.

Siding is removed temporarily as necessary and 29/16" holes are drilled through the wall sheathing. A fill tube is inserted up (and down) into walls cavities to not only fill, but dense pack wall cavities. Dense packaging is a technique that packs the insulation very tightly - so tightly that the irregular shaped cavities and crevices in the wall cavities are filled, and air will not penetrate the dense packed cellulose. It's remarkable, and something that can't be achieved with fiberglass - not even close! Dense packed cellulose stops air flow through the wall and insulates. TruSoft™ Cellulose is treated to be highly fire, mold, and pest resistant. Holes are plugged and siding is put back. With wood siding, old nail holes and new nails may be noticeable on close inspection. Very small new nails will be visible on aluminum siding. (If specified, Siding will be removed but drilled and plugged instead).

Results after dense packing Insulation - A less drafty, warmer, quieter, more comfortable house, less dust/pollen, house not so dry in winter, lower fuel/electric bills, heating system runs less - less maintenance.
