The only problem is, choosing a replacement window can get tricky because you have all these terms being thrown around. I\u2019m here to address that, covering the basics to help you understand window glass better and assist you in choosing the right window for you.<\/p>\n<h3>Getting Started: A Few Important Terms<\/h3>\n<p>Window glass come with labels specifying ratings in certain criteria. Generally, these criteria include:<\/p>\n<ul>\n<li><u>R-Value<\/u>. The measure of thermal resistance, the R-value refers to a window\u2019s ability to <a href=\"https:\/\/www.kravelv.com\/home-insulation-the-essentials\/\" class=\"wpil_internal_link\" target=\"_blank\" rel=\"noopener\">insulate against the flow of heat from outside your home<\/a> to the inside, and vice versa. The higher the R-value, the better a window\u2019s thermal resistance is.<\/li>\n<li><u>U-Factor<\/u>. The measure of heat lost over time, the U-factor indicates how much heat escapes through the window per hour. For energy efficiency, you want a lower U-factor for your windows.<\/li>\n<\/ul>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-2402 aligncenter\" src=\"https:\/\/www.kravelv.com\/wp-content\/uploads\/2015\/09\/A-Guide-to-Window-Glass1.jpg\" alt=\"A Guide to Window Glass1\" width=\"400\" height=\"325\"><\/p>\n<ul>\n<li><u>Solar <a href=\"https:\/\/www.kravelv.com\/5-ways-reduce-heat-gain\/\" class=\"wpil_internal_link\" target=\"_blank\" rel=\"noopener\">Heat Gain<\/a> Coefficient.<\/u> The measure of how much heat enters a building while the sun is shining, ideal SHGC will depend on the kind of climate you live in. In warmer climates, where cooling needs are high, you\u2019ll want a low SHGC, to minimize the amount of heat entering your home. On the other hand, in colder climates, you\u2019ll want a higher SHGC, so you can take advantage of heating from the sun to help meet your heating requirements.<\/li>\n<li><u>Visible Transmittance<\/u>. The measure of how much sunlight a window lets in, VT determines how helpful a window will be when it comes to daylighting. The higher the VT, the higher the amount of natural light that will be let in.<\/li>\n<\/ul>\n<h3>About the Glass<\/h3>\n<p>You will also encounter <a href=\"http:\/\/www.energy.gov\/energysaver\/articles\/window-types\">different window glass<\/a> options, like:<\/p>\n<ul>\n<li><u>Double-Pane Glass. <\/u>Also known as double-glazed glass, it\u2019s the standard glazing <a href=\"https:\/\/www.kravelv.com\/your-top-6-long-lasting-roofing-options-today\/\" class=\"wpil_internal_link\" target=\"_blank\" rel=\"noopener\">option today,<\/a> made up of two panes of glass separated by a layer of air or inert gas like argon or krypton. The more panes a window has, the higher the level of insulation it provides so you can expect double-paned <a href=\"https:\/\/www.kravelv.com\/rating-window-performance-what-it-all-means\/\" class=\"wpil_internal_link\" target=\"_blank\" rel=\"noopener\">windows to perform<\/a> better than their single-paned counterparts.<\/li>\n<\/ul>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-2403 aligncenter\" src=\"https:\/\/www.kravelv.com\/wp-content\/uploads\/2015\/09\/A-Guide-to-Window-Glass2.jpg\" alt=\"A Guide to Window Glass2\" width=\"400\" height=\"325\"><\/p>\n<ul>\n<li><u>Low-emissivity Glass. <\/u>Also called low-E glass, this glass option comes with a very thin metallic oxide coating that limits the entry of radiant heat and ultraviolet light, reducing heat that can affect indoor comfort and fading in furniture and other items close to the window without affecting visible transmittance.<\/li>\n<\/ul>\n<ul>\n<li><u>Tinted glass.<\/u> As it reduces heat and glare from sunlight and also blocks UV light, tinted glass functions similarly to low-E glass. However, they differ in that tinted glass cuts back on a window\u2019s visible transmittance, meaning it lets in less natural light compared to low-E glass. Just how much a window blocks will depend on the kind of tint it uses. The most common gray and bronze tints reduce heat and light more or less equally, while blue and green tints let in more light than heat, and black tints block more light than heat.<\/li>\n<\/ul>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-2404 aligncenter\" src=\"https:\/\/www.kravelv.com\/wp-content\/uploads\/2015\/09\/A-Guide-to-Window-Glass3.jpg\" alt=\"A Guide to Window Glass3\" width=\"400\" height=\"325\"><\/p>\n<h3>Choosing the Right Window Glass<\/h3>\n<p>The <a href=\"http:\/\/www.hometips.com\/buying-guides\/selecting-window-glass.html\">right window glass<\/a> for is one that addresses specific requirements put forth by the climate you live in. For instance, those in hotter climates, you\u2019ll want a window that lets in less heat so look for windows that offer the lowest U-factor and SHGC. Those in colder areas, on the other hand, will benefit from windows with high SHGC that will help heat your home during the day, but with low U-factor, so that the heat that does enter your house doesn\u2019t dissipate too fast.<\/p>\n<p>====================<\/p>\n<p><span style=\"text-decoration: underline;\"><strong>Author Bio:<\/strong><\/span><\/p>\n<p><em><strong>Scott Barr<\/strong><\/em> currently heads <a href=\"http:\/\/www.southwestexteriors.com\/\">Southwest Exteriors<\/a> and has been with the company since 1990.&nbsp; He\u2019s committed to delivering the \u201cUltimate Client Experience\u201d so he finds great enjoyment in hearing customers talk (even rave) about how satisfied they are with their home improvement project.
