Airtightness: The Key to Energy Efficiency and Everyday Comfort
Research shows airtightness has a greater impact on a home’s energy use than any other single factor. If you want a home that performs well year-round, start with airtightness.
Energy Star Benefits Of Airsealing
According to ENERGY STAR®, the U.S. Environmental Protection Agency’s trusted energy efficiency program, air leakage can account for 25–40% of the energy used for heating and cooling in a typical home. Air leakage doesn’t just waste energy—it also reduces indoor comfort, allows in moisture, dust, and pollutants, and increases the risk of mould and structural damage.
