As home comfort experts, we like to explain the stack effect to our customers. The basic gist of it is that warm air escapes through the top of your house and cold air comes in through the bottom. In preparation for this coming winter, the homeowner wanted to have their basement treated.
One of the main components that goes into treating a basement is air sealing the rim joists. For this homeowner, we applied SilverGlo Polysio Foam Board as a base layer. We then applied a layer of spray foam insulation over the foam board. The combination worked terrifically to protect this home from cold drafts in the winter.
