Even so, with the various options and choices that can be made regarding insulation, knowing about R50 is a helpful piece of knowledge to have.<\/p>\n\n\n\n<p>This article will discuss not only R50 but also R49 and the differences between the two, and why R49 tends to be more common. Most importantly, though, in this article, you will find a straightforward and easy-to-read table for R49 and R50 thicknesses.<\/p>\n\n\n<div class=\"lazyblock-nutshell-Z1XQg8d wp-block-lazyblock-nutshell\"><p class=\"has-text-align-left has-text-color has-background\" style=\"background-color:#e7d1b1;color:#575f60;font-size:18px\"><noscript><img loading=\"lazy\" decoding=\"async\" width=\"200\" height=\"50\" class=\"wp-image-3497\" style=\"width: 200px;\" src=\"https:\/\/thetibble.com\/wp-content\/uploads\/2021\/08\/nutshell1-11.png\" alt=\"\" srcset=\"https:\/\/thetibble.com\/wp-content\/uploads\/2021\/08\/nutshell1-11.png 600w, https:\/\/thetibble.com\/wp-content\/uploads\/2021\/08\/nutshell1-11-300x75.png 300w\" sizes=\"(max-width: 200px) 100vw, 200px\"><\/noscript><img loading=\"eager\" decoding=\"async\" width=\"200\" height=\"50\" class=\"wp-image-3497 eager-load\" style=\"width: 200px;\" src=\"data:image\/svg+xml,%3Csvg%20xmlns='http:\/\/www.w3.org\/2000\/svg'%20viewBox='0%200%20200%2050'%3E%3Crect%20width='200'%20height='50'%20style='fill:%23e3e3e3'\/%3E%3C\/svg%3E\" alt=\"\" sizes=\"(max-width: 200px) 100vw, 200px\" data-pin-media=\"https:\/\/thetibble.com\/wp-content\/uploads\/2021\/08\/nutshell1-11.png\" id=\"mv-trellis-img-1\" data-src=\"https:\/\/thetibble.com\/wp-content\/uploads\/2021\/08\/nutshell1-11.png.webp\" data-srcset=\"https:\/\/thetibble.com\/wp-content\/uploads\/2021\/08\/nutshell1-11.png.webp 600w, https:\/\/thetibble.com\/wp-content\/uploads\/2021\/08\/nutshell1-11-300x75.png.webp 300w\" data-svg=\"1\" data-trellis-processed=\"1\"><br><strong>R49 is more commonly specified. R50 can be used instead, but the greater cost is not necessarily matched with greater insulating power. The thinnest layer achieving R50 is 8.3\" with closed cell spray foam. The thickest layer achieving R50 is 20.8\" with loose-fill fiberglass.<\/strong> <\/p><\/div>\n\n\n<h2 class=\"wp-block-heading\">R49 vs R50<\/h2>\n\n\n\n<p>R50 insulation isn&rsquo;t commonly discussed. R49 is much more common. <\/p>\n\n\n\n<p>This is mostly because the increase from R49 to R50 doesn&rsquo;t really offer a notable difference as far as improved function of the insulation. It would be like adding more insulation (so more cost) for essentially the same perks as what is offered with slightly less insulation. <\/p>\n\n\n\n<p>It is also easier to find sellers who sell amounts of their insulation that equate to R49. It is more uncommon, on the other hand, to find that type of situation for R50. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Where Is R49\/R50 Insulation Required?<\/h2>\n\n\n\n<p>Insulation R-values of 49 and 50 are relatively heavy-duty ratings.<\/p>\n\n\n\n<p>Both R49 and R50 stop around 98-99% of the heat that could pass through solid materials. <\/p>\n\n\n\n<p>Having higher insulation ratings, R49 or R50 insulation is most commonly used in attics.

This is because a great deal of heat can be lost through these high points, so having a thicker amount of insulation there is more important for keeping heat in. <\/p>\n\n\n\n<p>Attics also tend to hold a lot of heat. So, thick insulation is important in an attic in order to protect the areas of the home that have a regulated temperature. <\/p>\n\n\n\n<p>For example, in a hot summer if you had your air conditioning on and the house was kept at 68 &deg;F, the attic may still be extremely warm. It is not uncommon for attics to reach temperatures of 140 &deg;F!<\/p>\n\n\n\n<p>This heat can affect the temperature of rooms below it, making your HVAC system work harder to maintain the low desired temperature.<\/p>\n\n\n\n<p>R49 or R50 insulation is then very valuable as it prevents the extreme heat in the attic from impacting the areas of the home that are trying to be kept cool.  <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Only Some Climate Zones Require R49\/R50<\/h3>\n\n\n\n<p>Only certain climate zones require R49 or R50 insulation. <a rel=\"noreferrer noopener\" href=\"https:\/\/codes.iccsafe.org\/content\/IRC2021P2\/chapter-11-re-energy-efficiency#IRC2021P2_Pt04_Ch11_SecN1102.1.3\" target=\"_blank\">Table N1102.1.3<\/a> of the International Residential Code (IRC) explicitly explains these regulations.<\/p>\n\n\n\n<p>R49 is only required in the ceilings of zones 2 and 3 (which are hot climates). R50 is not explicitly required anywhere, but could be used in place of R49.<\/p>\n\n\n\n<p>Some states included in zones 2 and 3 are Florida, Louisiana, and Alabama. These climates need thicker insulation in the ceiling so that the oppressive heat, which is so common there, is not seeping into the house and impacting the temperature within the home. <\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><noscript><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"729\" src=\"https:\/\/thetibble.com\/wp-content\/uploads\/2023\/03\/Zone-2-and-3-with-hot-climates-including-Florida-Alabama-and-Louisiana-need-thicker-insulation-in-the-ceiling-with-R49-or-R50.jpg\" alt=\"Zone 2 and 3 with hot climates including Florida, Alabama and Louisiana need thicker insulation in the ceiling with R49 or R50.jpg\" class=\"wp-image-30939\" srcset=\"https:\/\/thetibble.com\/wp-content\/uploads\/2023\/03\/Zone-2-and-3-with-hot-climates-including-Florida-Alabama-and-Louisiana-need-thicker-insulation-in-the-ceiling-with-R49-or-R50.jpg 1000w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/03\/Zone-2-and-3-with-hot-climates-including-Florida-Alabama-and-Louisiana-need-thicker-insulation-in-the-ceiling-with-R49-or-R50-300x219.jpg 300w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/03\/Zone-2-and-3-with-hot-climates-including-Florida-Alabama-and-Louisiana-need-thicker-insulation-in-the-ceiling-with-R49-or-R50-768x560.jpg 768w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/03\/Zone-2-and-3-with-hot-climates-including-Florida-Alabama-and-Louisiana-need-thicker-insulation-in-the-ceiling-with-R49-or-R50-960x700.jpg 960w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/03\/Zone-2-and-3-with-hot-climates-including-Florida-Alabama-and-Louisiana-need-thicker-insulation-in-the-ceiling-with-R49-or-R50-150x109.jpg 150w\" sizes=\"(max-width: 760px) calc(100vw - 24px), 720px\"><\/noscript><img loading=\"lazy\" decoding=\"async\" width=\"1000\" height=\"729\" src=\"https:\/\/thetibble.com\/wp-content\/uploads\/2023\/03\/Zone-2-and-3-with-hot-climates-including-Florida-Alabama-and-Louisiana-need-thicker-insulation-in-the-ceiling-with-R49-or-R50.jpg.webp\" alt=\"Zone 2 and 3 with hot climates including Florida, Alabama and Louisiana need thicker insulation in the ceiling with R49 or R50.jpg\" class=\"wp-image-30939 lazyload\" srcset=\"https:\/\/thetibble.com\/wp-content\/uploads\/2023\/03\/Zone-2-and-3-with-hot-climates-including-Florida-Alabama-and-Louisiana-need-thicker-insulation-in-the-ceiling-with-R49-or-R50.jpg.webp 1000w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/03\/Zone-2-and-3-with-hot-climates-including-Florida-Alabama-and-Louisiana-need-thicker-insulation-in-the-ceiling-with-R49-or-R50-300x219.jpg.webp 300w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/03\/Zone-2-and-3-with-hot-climates-including-Florida-Alabama-and-Louisiana-need-thicker-insulation-in-the-ceiling-with-R49-or-R50-768x560.jpg.webp 768w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/03\/Zone-2-and-3-with-hot-climates-including-Florida-Alabama-and-Louisiana-need-thicker-insulation-in-the-ceiling-with-R49-or-R50-960x700.jpg.webp 960w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/03\/Zone-2-and-3-with-hot-climates-including-Florida-Alabama-and-Louisiana-need-thicker-insulation-in-the-ceiling-with-R49-or-R50-150x109.jpg.webp 150w\" sizes=\"(max-width: 760px) calc(100vw - 24px), 720px\" data-pin-media=\"https:\/\/thetibble.com\/wp-content\/uploads\/2023\/03\/Zone-2-and-3-with-hot-climates-including-Florida-Alabama-and-Louisiana-need-thicker-insulation-in-the-ceiling-with-R49-or-R50.jpg\" id=\"mv-trellis-img-3\" data-trellis-processed=\"1\"><\/figure>\n\n\n\n<p>Having thicker insulation in the ceilings and attics can also be helpful in reducing the noise of weather.
