U-factor values typically range from 0.25 to 1.25 and are expressed in Btu\/h\u00b7ft\u00b2\u00b7\u00b0F. A lower U-factor signifies more effective insulation. (EPA mandates that ENERGY STAR products display a certified and listed U-Factor on the product label.)<\/p>\n SHGC assesses the portion of solar energy that passes through and reveals how well the product blocks heat generated by sunlight. It is quantified on a scale from 0 to 1, with values typically falling between 0.25 and 0.80. A lower SHGC indicates reduced transmission of solar heat. (EPA requires ENERGY STAR-labelled products to display a certified SHGC value on the product label.)<\/p>\n AL quantifies the rate at which air flows through seams in the window. AL is measured in cubic feet of air passing through one square foot of window area per minute. A lower AL value signifies less air leakage. Most industry standards and building codes stipulate an AL of 0.3 cf\u00b7m\/ft\u00b2. (EPA mandates certification of AL for ENERGY STAR labeled products.)<\/p>\n Also Read: How Energy-Efficient Windows Keep Heat Out During Summer<\/a><\/strong><\/p>\n VT quantifies the quantity of light permitted through the window. It is assessed on a scale from 0 to 1, with typical values ranging from 0.20 to 0.80. A higher VT indicates greater light penetration.<\/p>\n This metric assesses how effectively the window resists water accumulation. Condensation Resistance is rated on a scale from 0 to 100. A higher condensation resistance factor suggests less susceptibility to moisture buildup within the window.<\/p>\n Picture Source – EcoTech Windows & Doors<\/em><\/p>\n It’s vital to choose windows with U-factor and SHGC values that align with your specific climate zone.
