When your house is heated, the pressure inside the house is higher than that outside. Because of this higher pressure the heated air in the house leaks out through unintentional openings causing unnecessary and unwanted heat loss.
Energy researchers have discovered that sealing air leaks is one of the simplest and least expensive ways to save energy in homes. A well insulated house loses about 40% of its heat through ventilation and almost 20% through unwanted air leakage.
A few hours of air sealing with inexpensive sealants can often reduce the air leakage by 50% or more, resulting in a saving of 10% of the total house heating bill.
