Defining Features of Polaris Windows

Volume of outside air passing into a building is measured in cubic feet per minute. The maximum air leakage rate allowed
by AAMA is .30 cfm/ft2. The lower the air leakage rate, the better a product is at keeping air out. Our windows are
proven to be virtually air tight with air infiltration ratings as low as .01. They perform up to 30 times better than competitors.
