Rim Joist Insulation
In a typical home, the rim joist area is a huge source of energy loss. It often lacks proper air sealing, so outside air is consistently leaking in through the wood joints, corner, gaps and openings drilled for electric wires, plumbing and ducts. The results can be felt throughout the house in the form of cold floors, drafty rooms and high energy bills. By using spray foam, our team was able to insulate and seal the gaps and holes in the rim joist, stopping air leakages in one simple step.
Open-Cell Spray Foam
Insulating with open-cell spray foam under the roof deck is an excellent choice when the HVAC ducts run through the attic. Spray foam is most commonly applied in the space between the attic rafters. It seals all of the air-leakage gaps and spaces, and provides very high R-value in one step. The result will be a conditioned attic space. This means, in the summer, cooled air traveling through the ducts will no longer be warmed by hot attic air, and heated air will no longer be lost in the winter on its way to the rooms.
Chimney Insulation
For safety, it is important that a masonry chimney not be touching combustible materials such as wood, fiberglass insulation, or foam. The answer is to wrap the chimney with Rockwool, a non-combustible fireproof mineral fiber. Then, for added R-value, SilverGlo foam insulation can be installed and sealed against the Rockwool.
