We use polyurethane foam to close all accessible penetrations and top plates.
Here we are installing a layer of 4" SilverGlo along the attic deck. This will then be covered with 3/8" board.
Encapsulating the duct system with polyurethane spray foam
TruSoft Cellulose insulation is blown into the attic to an R value of 60
Vertical insulation retention dams are installed to hold the blown in insulation in place.
A homeowner in Jeffersonton, VA wanted to make their upstairs level more comfortable all year long. The Comfenergy team did several things to achieve this. First, we removed the existing insulation that was old and dirty. Then we installed a super deck which consists of 4" of SilverGlo along the attic deck and then is covered with 3/8" board. We air sealed and insulated the attic, using spray foam and cellulose insulation, and installed a metal chimney wrap. We encapsulated the duct system in the attic with polyurethane spray foam and finally, installed a Davis Lewis scuttle hatch cover.
