And, because it is not as cold out, a great deal of heat does not need to be kept in. <\/p>\n\n\n\n<p>R30 insulation stops between 96% and 97% of the heat that would get through via conduction. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Walls<\/h3>\n\n\n\n<p>On the whole, walls require lower R-value ratings, so the climates where R30 is listed for use in walls (see <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>) are very different to where it is required in ceilings. <\/p>\n\n\n\n<p>Zones 4-8 (marine zone 4 included) require R30 insulation to be used in walls. States in these zones include Kentucky, Nevada, Ohio, Montana, Alaska, and some Alaskan boroughs are included in zone 8. <\/p>\n\n\n\n<p>These zones require R30 insulation in their walls either because they are exposed to very cold climates constantly, or they have the potential to encounter such temperatures.<\/p>\n\n\n\n<p>In these areas, R30 is required so that heat is retained in the home. In such zones it would be rare that the goal of R30 insulation in the walls is to keep heat out, except in zone 4, which runs along the northern portions of the southern United States. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Floors<\/h3>\n\n\n\n<p><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 IRC describes when R30 insulation is required in floors as well. Again, R30 is quite a high rating when it comes to floor insulation.<\/p>\n\n\n\n<p>Zone 5, marine 4, and zone 6 are the only ones that require that R30 insulation is used in the floors. States in these zones include Nevada, parts of Washington state, parts of Oregon, and Montana.<\/p>\n\n\n\n<p><strong>It is important to note that zone 4 (excluding marine zone 4) does not require R30 insulation in their floors.<\/strong> This would include a state like Kentucky.  <\/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\/2022\/11\/Man-in-PPE-installing-mineral-wool-insulation-on-the-floor-at-the-attic.jpg\" alt=\"Man in PPE installing mineral wool insulation on the floor at the attic\" class=\"wp-image-25678\" srcset=\"https:\/\/thetibble.com\/wp-content\/uploads\/2022\/11\/Man-in-PPE-installing-mineral-wool-insulation-on-the-floor-at-the-attic.jpg 1000w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/11\/Man-in-PPE-installing-mineral-wool-insulation-on-the-floor-at-the-attic-300x219.jpg 300w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/11\/Man-in-PPE-installing-mineral-wool-insulation-on-the-floor-at-the-attic-768x560.jpg 768w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/11\/Man-in-PPE-installing-mineral-wool-insulation-on-the-floor-at-the-attic-735x536.jpg 735w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/11\/Man-in-PPE-installing-mineral-wool-insulation-on-the-floor-at-the-attic-335x244.jpg 335w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/11\/Man-in-PPE-installing-mineral-wool-insulation-on-the-floor-at-the-attic-347x253.jpg 347w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/11\/Man-in-PPE-installing-mineral-wool-insulation-on-the-floor-at-the-attic-520x379.jpg 520w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/11\/Man-in-PPE-installing-mineral-wool-insulation-on-the-floor-at-the-attic-640x467.jpg 640w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/11\/Man-in-PPE-installing-mineral-wool-insulation-on-the-floor-at-the-attic-960x700.jpg 960w\" 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\/2022\/11\/Man-in-PPE-installing-mineral-wool-insulation-on-the-floor-at-the-attic.jpg.webp\" alt=\"Man in PPE installing mineral wool insulation on the floor at the attic\" class=\"wp-image-25678 lazyload\" srcset=\"https:\/\/thetibble.com\/wp-content\/uploads\/2022\/11\/Man-in-PPE-installing-mineral-wool-insulation-on-the-floor-at-the-attic.jpg.webp 1000w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/11\/Man-in-PPE-installing-mineral-wool-insulation-on-the-floor-at-the-attic-300x219.jpg.webp 300w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/11\/Man-in-PPE-installing-mineral-wool-insulation-on-the-floor-at-the-attic-768x560.jpg.webp 768w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/11\/Man-in-PPE-installing-mineral-wool-insulation-on-the-floor-at-the-attic-735x536.jpg.webp 735w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/11\/Man-in-PPE-installing-mineral-wool-insulation-on-the-floor-at-the-attic-335x244.jpg.webp 335w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/11\/Man-in-PPE-installing-mineral-wool-insulation-on-the-floor-at-the-attic-347x253.jpg.webp 347w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/11\/Man-in-PPE-installing-mineral-wool-insulation-on-the-floor-at-the-attic-520x379.jpg.webp 520w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/11\/Man-in-PPE-installing-mineral-wool-insulation-on-the-floor-at-the-attic-640x467.jpg.webp 640w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/11\/Man-in-PPE-installing-mineral-wool-insulation-on-the-floor-at-the-attic-960x700.jpg.webp 960w\" sizes=\"(max-width: 760px) calc(100vw - 24px), 720px\" data-pin-media=\"https:\/\/thetibble.com\/wp-content\/uploads\/2022\/11\/Man-in-PPE-installing-mineral-wool-insulation-on-the-floor-at-the-attic.jpg\" id=\"mv-trellis-img-3\" data-trellis-processed=\"1\"><\/figure>\n\n\n\n<p>These areas require R30 insulation in their floors because it is a little thicker and these zones are exposed to somewhat colder temperatures. And with having the insulation in the floors, the goal is to keep heat in the desired areas of the home. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Only Some Climate Zones Require R30<\/h3>\n\n\n\n<p>Zones 0, 1, and 4 through 8 (including marine zone 4) in some fashion require the use of R30 insulation, whether ceilings, floors, or walls. <\/p>\n\n\n\n<p>The only zones that don&rsquo;t require R30 insulation in any facet are zones 2 and 3. Some states that reside in these zones are Alabama, most of Florida, and most of Texas. <\/p>\n\n\n\n<p>These areas don&rsquo;t require R30 at all because of the intense heat they are normally encountering. As such, the insulation that is required is either thinner than R30 or thicker than R30. <\/p>\n\n\n\n<p>Insulation thicker than R30 is required in these climates (specifically in the ceiling) so that temperature control (e.g., air conditioning) can more effectively be kept in the house. And insulation thinner than R30 is used so that heat within the house can more easily pass outside of it. <\/p>\n\n\n\n<h2 class=\"wp-block-heading\">R30 Insulation Thickness Guide: Table<\/h2>\n\n\n\n<figure class=\"wp-block-table\"><table><tbody><tr><td class=\"has-text-align-center\" data-align=\"center\"><strong>Insulation Type<\/strong><\/td><td class=\"has-text-align-center\" data-align=\"center\"><strong>Inherent R-value (per inch thickness)<\/strong><\/td><td class=\"has-text-align-center\" data-align=\"center\"><strong>Thickness to achieve R30<\/strong><\/td><td class=\"has-text-align-center\" data-align=\"center\"><strong>Best-selling option<\/strong><\/td><\/tr><tr><td class=\"has-text-align-center\" data-align=\"center\"><a href=\"https:\/\/thetibble.com\/fiberglass-insulation-complete-guide\/\" data-type=\"post\" data-id=\"23842\">Loose-fill fiberglass<\/a> <\/td><td class=\"has-text-align-center\" data-align=\"center\">2.2-2.7<\/td><td class=\"has-text-align-center\" data-align=\"center\">&plusmn;
