It measures how much solar heat passes through a window and enters a building. The rating ranges from 0 to 1, with lower numbers blocking more solar heat.<\/p><h4 data-section-id=\"1wlsq2k\" data-start=\"555\" data-end=\"581\">Is a SHGC of .27 good?<\/h4><p data-start=\"583\" data-end=\"805\">Yes. An <strong data-start=\"591\" data-end=\"607\">SHGC of 0.27<\/strong> is considered very good for warm and many mixed climates because it blocks a significant amount of solar heat while still allowing natural light into the home.<\/p><h4 data-section-id=\"z5pe0o\" data-start=\"807\" data-end=\"837\">Is the 0.28 U-factor good?<\/h4><p data-start=\"839\" data-end=\"1093\" data-is-last-node=\"\" data-is-only-node=\"\">Yes. A <strong data-start=\"846\" data-end=\"866\">U-Factor of 0.28<\/strong> is generally considered energy-efficient and provides good insulation. It helps reduce heat loss and is suitable for many residential applications, especially in mixed and colder climates.<\/p><\/div><\/div><\/div><\/div><\/div><\/div><\/section><\/div><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"<p>SHGC measures how much solar heat enters through a window.
