Infiltration is the loss or gain of heat through areas where inside and outside air meet. Many homes lose up to 30-40% of the energy used for heating and cooling through such leaks. Leaks are most common at outside doors that do not fit well or poorly set windows. Plugging these leaks is one of the easiest and cheapest ways to conserve energy. All Desert House joints are sealed with caulk and all doors and windows that open are equipped with weather stripping.
