Spray Foam Insulation - Exterior Walls

Exterior walls are often not properly air sealed and typically only insulted with fiberglass batts, which settle over time. This allows for convective looping to occur. In convective looping, warm conditioned air meets a cold exterior wall and gives up its heat. The now cold air falls and the cycle continues, this leaves homeowners feeling drafts and is a big reason room feel much colder around the edges. To combat this, the homeowners chose to insulate with Closed Cell Spray Foam which will both air seal the wall cavities and provides a higher R-value per inch.
