When the floor over your garage, balcony, or porch is inadequately sealed, air can leak through various locations, like the structural framing. With air leaks present, many problems can arise; freezing pipes, chilled duct runs that prevent the HVAC system from functioning properly, and of course cold floors.
Air sealing the floor cavity efficiently is key in deterring air leaks. Kingston's Insulating Solutions will apply sprayfoam at the band joist area and the subfloor as well as any penetrations in the floor, allowing for complete air and vapour sealing. A floor cavity that is sealed improperly has a considerably reduced R-value and is basically comparable to a floor cavity that has no insulation at all.
Exposed Cottage Floors
Cottage floors have many penetrations and that aren't completely contained within the floor cavity. It is difficult to install an air barrier in a crawlspace without moving these protrusions into the conditioned space. Applying Sprayfoam Insulation under the wood floors or under subflooring not only creates an air seal and insulates the floor, but it also seals all the cracks and holes where rodents and insects enter our homes. The foam also will protect your wood floors from soil moisture rising from the ground to slowly rot your wood.
