Eliminate the Stack Effect
Rim Joist Sealing and Insulation
The floors in your home make up a substantial portion of square footage. Defects or gaps in the framing allow air to move through these building assemblies which leads to heat loss or gain. This can lead to higher utility bills and cold floors. Sealing the rim joists established a continuous air barrier and thermal boundary.
How it works
The easiest and best way to seal and insulate your rim joists is by using two-part closed cell spray foam. By using spray foam, we can obtain an air barrier and a targeted R-value using one product and in one step.
We will often remove insulation prior to remodeling work beginning. Especially when the home is occupied during the remodel. It makes it much easier for the different trades to work in the attic and they are not tracking the insulation back into the home.
Lastly, we sometimes remove insulation do better gain access to air sealing. Depending on the depth of the current insulation, roof pitch and access, removing the old, dirty insulation allows 100% access to all areas for air sealing. Having a “clean slate” so to speak, ensures nothing is missed during the air sealing process.
