Tired Of Massive Heating Bills In The Winter? Your Exterior Walls May Be Poorly Insulated. Here's How Spray Foam Can Fix It
Many older homes simply used an air cavity as a method of insulation — an empty air gap is the only thing that stands between your exterior walls and your interior walls. While an air gap slows down thermal exchange, it still allows a large amount of cold outside air to infiltrate into your home. Some of the heated air inside your home will also escape outside. This air exchange causes the inside of your home to rapidly cool down, forcing your heater to work harder and increasing your energy bills.
