By using low U\u2011factor glass, quality frames, and coatings, energy\u2011efficient windows <strong data-start=\"850\" data-end=\"878\">slow heat loss and entry<\/strong>, improving comfort and lowering heating\/cooling bills in most climates.<\/p><h4 data-start=\"990\" data-end=\"1243\">Is .27 a good U\u2011factor for windows?<\/h4><p data-start=\"990\" data-end=\"1243\" data-is-last-node=\"\" data-is-only-node=\"\">A U\u2011factor of <strong data-start=\"1046\" data-end=\"1093\">.27 is generally good for energy efficiency<\/strong>, especially in many climate zones. Lower U\u2011factors (like .20\u2013.30) mean better insulation and lower energy loss.<\/p><\/div><\/div><\/div><\/div><\/div><\/div><\/section><\/div><\/div><\/div><\/div><\/div><\/section><\/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>Energy\u2011efficient windows reduce heat loss and gain with multi\u2011pane glass, Low\u2011E coatings, gas fills, and proper installation, cutting energy bills and improving comfort.<\/p>","protected":false},"author":2,"featured_media":3215,"comment_status":"open","ping_status":"open","sticky":false,"template":"elementor_theme","format":"standard","meta":{"footnotes":""},"categories":[43],"tags":[52],"class_list":["post-3630","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-others","tag-windows"],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.gohomeguide.com\/it\/wp-json\/wp\/v2\/posts\/3630","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.gohomeguide.com\/it\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.gohomeguide.com\/it\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.gohomeguide.com\/it\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.gohomeguide.com\/it\/wp-json\/wp\/v2\/comments?post=3630"}],"version-history":[{"count":10,"href":"https:\/\/www.gohomeguide.com\/it\/wp-json\/wp\/v2\/posts\/3630\/revisions"}],"predecessor-version":[{"id":3644,"href":"https:\/\/www.gohomeguide.com\/it\/wp-json\/wp\/v2\/posts\/3630\/revisions\/3644"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.gohomeguide.com\/it\/wp-json\/wp\/v2\/media\/3215"}],"wp:attachment":[{"href":"https:\/\/www.gohomeguide.com\/it\/wp-json\/wp\/v2\/media?parent=3630"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.gohomeguide.com\/it\/wp-json\/wp\/v2\/categories?post=3630"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.gohomeguide.com\/it\/wp-json\/wp\/v2\/tags?post=3630"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
