A poorly insulated attic with 15
This attic was poorly insulated. Only 15 in' thick wool was available. The thermal value observed by the inspector was R17. However, he recommended to the client that it needs to be at least R50.
Ventilation mats and insulation of recessed lights
Once the wool was removed, our team was able to install the ventilation mats in the soffits. They allow for good air circulation in the attic and retain cellulose. Our team also insulated the electrical boxes of the lights by installing our TiteShell protective boxes and sealing it with polyurethane foam.
Low wall to facilitate access to the attic
Our team installs a low wall around the access to retain the cellulose around and easily access the attic.
Insulation of the attic access hatch
Our team insulated the attic access hatch as it represents a major air leak.
16 in of cellulose for an R60 value
Our team blew 16 inches of cellulose to achieve an R60 value for Mr. Lebel's attic. For comparison purposes, it would take at least 22 gp with wool to have the same effectiveness.
Overview of the attic once insulated with cellulose
Here is the result of Mr. Lebel's attic insulated with cellulose fiber and having an R60 value.
