How Spray Foam Works

All structures, including your home, have air gaps and crevices that allow air to infiltrate the building. When air from the outside replaces the air in your home, it is called a “natural air change”. Many homes can have more than 3 natural air changes per hour. This means the conditioned air inside your home could leak out and be replaced by outside air up to 70 times a day, requiring you to heat or cool that outside air that continues to infiltrate your home. Demilec’s spray foam is much more than a great insulation. It expands up to 120 times to fill every crack, gap and void to create an air barrier, dramatically reducing the energy consumption of your home.
