A double vapor barrier basically creates a sandwich of soggy insulation with impermeable facing on either side.&nbsp;<\/p>\n\n\n\n<p>Insulation will encounter moisture one way or another&mdash;from construction moisture that lingers, from water leaks, or from humidity and condensation. It needs to be able to escape through some kind of permeable material.<\/p>\n\n\n\n<p>Condensation can cause the insulation to get <a href=\"https:\/\/thetibble.com\/dangers-wet-insulation-risks-smells-efficiency-loss\/\">moldy<\/a>. Moisture also <a href=\"https:\/\/thetibble.com\/wet-insulation-still-insulate\/\">reduces the R-value<\/a> of the insulation.<\/p>\n\n\n\n<p>Basically, a wall needs to be able to dry in one direction. It either dries towards the exterior (cold climates) or towards the interior (warm climates).<\/p>\n\n\n\n<p>As Joseph Lstiburek of Building Science Corporation tells us in his article <a rel=\"noreferrer noopener\" href=\"https:\/\/buildingscience.com\/documents\/insights\/bsi-073-macbeth-does-vapor-barriers\" target=\"_blank\">&ldquo;Macbeth Does Vapor Barriers&rdquo;<\/a>, remember the phrase <strong><em>&ldquo;Double, Double, Toil and Trouble&rdquo;<\/em><\/strong>!<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">The Paper Is Flammable<\/h3>\n\n\n\n<p>Almost all faced insulation is combustible. Paper and plastic facing will burn and, in the case of plastic facing, can release fumes while burning. Fiberglass insulation itself is not combustible, but as soon as you add Kraft facing, it causes the whole unit of insulation plus facing to be classed as flammable.<\/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\/04\/Kraft-faced-fiberglass-insulation-illustration-1.jpg\" alt=\"Kraft faced fiberglass insulation illustration\" class=\"wp-image-32237\" srcset=\"https:\/\/thetibble.com\/wp-content\/uploads\/2023\/04\/Kraft-faced-fiberglass-insulation-illustration-1.jpg 1000w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/04\/Kraft-faced-fiberglass-insulation-illustration-1-300x219.jpg 300w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/04\/Kraft-faced-fiberglass-insulation-illustration-1-768x560.jpg 768w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/04\/Kraft-faced-fiberglass-insulation-illustration-1-960x700.jpg 960w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/04\/Kraft-faced-fiberglass-insulation-illustration-1-150x109.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\/04\/Kraft-faced-fiberglass-insulation-illustration-1.jpg.webp\" alt=\"Kraft faced fiberglass insulation illustration\" class=\"wp-image-32237 lazyload\" srcset=\"https:\/\/thetibble.com\/wp-content\/uploads\/2023\/04\/Kraft-faced-fiberglass-insulation-illustration-1.jpg.webp 1000w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/04\/Kraft-faced-fiberglass-insulation-illustration-1-300x219.jpg.webp 300w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/04\/Kraft-faced-fiberglass-insulation-illustration-1-768x560.jpg.webp 768w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/04\/Kraft-faced-fiberglass-insulation-illustration-1-960x700.jpg.webp 960w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/04\/Kraft-faced-fiberglass-insulation-illustration-1-150x109.jpg.webp 150w\" sizes=\"(max-width: 760px) calc(100vw - 24px), 720px\" data-pin-media=\"https:\/\/thetibble.com\/wp-content\/uploads\/2023\/04\/Kraft-faced-fiberglass-insulation-illustration-1.jpg\" id=\"mv-trellis-img-4\" data-trellis-processed=\"1\"><\/figure>\n\n\n\n<p>The facing side of faced insulation <strong>can never be left exposed<\/strong>. Only flame-resistant foil (FSK-25) facing can be left exposed. In fact, the paper itself will be printed with a label that says &ldquo;Do not leave exposed.&rdquo;<\/p>\n\n\n\n<p>Basically, the kraft facing tells you &ldquo;If you can read this, something is wrong.&rdquo;&nbsp;<\/p>\n\n\n\n<p>Even so, you probably wouldn&rsquo;t leave kraft facing exposed if you&rsquo;re using it in interior walls. Your interior walls would presumably be <strong>finished with drywall<\/strong>. Gypsum wallboard (another name for drywall) is an acceptable fire barrier for insulation.<\/p>\n\n\n\n<p>People are more likely to leave kraft-faced insulation exposed in an unfinished attic, where it is a fire risk.<\/p>\n\n\n\n<p>Turning the paper against the wall satisfies the IRC in terms of fire safety. But then there would be no point in installing it. You might as well just use un-faced.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">It Is More Expensive to Buy Faced Insulation<\/h3>\n\n\n\n<p>Faced insulation is slightly more expensive than unfaced insulation. The cost difference is because the facing is an extra material that sometimes also needs to be treated or tested.<\/p>\n\n\n\n<p>It&rsquo;s a pretty minor difference, but we should never discount it, particularly for larger areas. <strong>Unfaced insulation typically costs about $0.50 to $1.75 <\/strong>per square foot. <strong>Faced insulation typically costs about $0.50 to $2.00<\/strong> per square foot.<\/p>\n\n\n\n<p>So, the cheapest faced insulation will be similar to the cheapest unfaced insulation. The cost difference comes into play in the upper range of products.<\/p>\n\n\n\n<p>The cost difference is worth it for exterior walls, especially in colder climates where you&rsquo;re often required by code to have a vapor barrier on the warm-in-winter side of exterior walls.<\/p>\n\n\n\n<p>If you had <strong>extra faced insulation left over, it would not hurt <\/strong>to use it in interior walls (as long as the vapor barrier is only on one side). But if you are buying insulation specifically for your interior walls, there is no particular reason to take on this additional cost.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Benefits of Kraft-Faced Insulation in Interior Walls<\/h2>\n\n\n\n<p>By far the main reason to use Kraft-faced insulation in interior walls is that it&rsquo;s <strong>easier to install.<\/strong> The paper facing means that the insulation won&rsquo;t fall down or sag like unfaced batts can do. Additionally, you can easily roll and cut faced insulation.&nbsp;<\/p>\n\n\n\n<p class=\"has-text-align-center\">\n    <a data-amazonimages=\"\" target=\"_blank\" title=\"2 Pack Owens Corning R-13 Pink Kraft Faced Fiberglass Insulation Roll 15 in. x 32 ft.

You won&rsquo;t need to wrestle with looser, less sturdy unfaced batts. So, if you&rsquo;re a DIYer&mdash;especially if you don&rsquo;t have much insulation experience&mdash;it might be worth it to spring for kraft-faced insulation.<\/p>\n\n\n\n<p>It&rsquo;s worth noting that Kraft-faced insulation is <strong>less sound-quieting<\/strong> than unfaced insulation. Still, there are ways of compensating for this and many contractors debate whether special sound-deadening insulation is even worth it.<\/p>\n\n\n\n<p>Doubling up on layers of drywall can often be just as effective at sound control.<\/p>\n\n\n\n<p>A vapor barrier can be helpful in walls between rooms that can get humid, such as<strong> bathrooms and kitchens<\/strong>.
