Photo Album: Attic insulation in Terrebonne, Qc

The problem The insulation in the attic of Mr. Gagnon's house was insufficient. There were only 10 in. and less fiberglass mats. Which was equivalent to an R-25 value. This made her home uncomfortable, rooms were often too hot in summer and too cold in winter, and her house’s energy costs were very high. The solution Reinsulate the attic to achieve an R-60 value and thus make the house more comfortable and energy efficient.

Overview of the attic before the work

There were only 10 in. and less fiberglass mats. This is equivalent to an R-25 value, which is far from sufficient for insulating an attic in Quebec.

Insulation of the duct system

The duct system was not isolated. We insulated it with polyurethane foam to prevent air loss.

Insulate the access hatch

We insulate the access hatch with our SilverGlo insulation to eliminate air leaks.

Overview of work

The exterior wall was insulated with SilverGlo, the chimney was sealed and insulated, then we blasted 16” of cellulose fiber to achieve an R-60 value!
