It is blown into wall, floor, or ceiling cavities. It can be used to insulate old homes or during new wall construction.<\/p>\n\n\n\n<p>Dry-blown cellulose insulation may settle and form gaps in the insulation, so dense-pack dry-blown cellulose can be used to reduce settling.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Wet-Sprayed Cellulose<\/h3>\n\n\n\n<p>Wet-sprayed cellulose is mixed with water during the spraying process, forming dense insulation. Moisture retardants (to prevent mold) or adhesives may be present in this type of cellulose insulation in small amounts.<\/p>\n\n\n\n<p>Wet-sprayed cellulose is appropriate for use during the construction of new walls.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Stabilized Cellulose<\/h3>\n\n\n\n<p>Stabilized cellulose is similar to wet-sprayed cellulose, but a small amount of water is added only to activate an adhesive to reduce settling.<\/p>\n\n\n\n<p>Stabilized cellulose is ideal for attic and roof insulation, especially in sloped roofs as the adhesive reduces the weight of the insulation and reduces the chances of ceiling sagging.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Low-Dust Cellulose<\/h3>\n\n\n\n<p>Low-dust cellulose has a small amount of oil or dust dampener to reduce the amount of dust created during installation. This form is advantageous for people who are sensitive to paper dust.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Is Cellulose Insulation Toxic?<\/h3>\n\n\n\n<p>As cellulose insulation is comprised of particles of milled paper, workers may be at risk of inhaling particles during installation.<\/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\/10\/Factory-for-paper-mill.jpg\" alt=\"Factory for paper mill\" class=\"wp-image-24023\" srcset=\"https:\/\/thetibble.com\/wp-content\/uploads\/2022\/10\/Factory-for-paper-mill.jpg 1000w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/10\/Factory-for-paper-mill-300x219.jpg 300w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/10\/Factory-for-paper-mill-768x560.jpg 768w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/10\/Factory-for-paper-mill-735x536.jpg 735w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/10\/Factory-for-paper-mill-335x244.jpg 335w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/10\/Factory-for-paper-mill-347x253.jpg 347w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/10\/Factory-for-paper-mill-520x379.jpg 520w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/10\/Factory-for-paper-mill-640x467.jpg 640w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/10\/Factory-for-paper-mill-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\/10\/Factory-for-paper-mill.jpg.webp\" alt=\"Factory for paper mill\" class=\"wp-image-24023 lazyload\" srcset=\"https:\/\/thetibble.com\/wp-content\/uploads\/2022\/10\/Factory-for-paper-mill.jpg.webp 1000w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/10\/Factory-for-paper-mill-300x219.jpg.webp 300w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/10\/Factory-for-paper-mill-768x560.jpg.webp 768w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/10\/Factory-for-paper-mill-735x536.jpg.webp 735w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/10\/Factory-for-paper-mill-335x244.jpg.webp 335w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/10\/Factory-for-paper-mill-347x253.jpg.webp 347w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/10\/Factory-for-paper-mill-520x379.jpg.webp 520w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/10\/Factory-for-paper-mill-640x467.jpg.webp 640w, https:\/\/thetibble.com\/wp-content\/uploads\/2022\/10\/Factory-for-paper-mill-960x700.jpg.webp 960w\" sizes=\"(max-width: 760px) calc(100vw - 24px), 720px\" data-pin-media=\"https:\/\/thetibble.com\/wp-content\/uploads\/2022\/10\/Factory-for-paper-mill.jpg\" id=\"mv-trellis-img-3\" data-trellis-processed=\"1\"><\/figure>\n\n\n\n<p>Similarly, the fire-retardant chemicals, such as <a rel=\"noreferrer noopener\" href=\"http:\/\/npic.orst.edu\/factsheets\/boricgen.html\" target=\"_blank\">boric acid<\/a>, borax, and ammonium sulfate, may be toxic if consumed or inhaled, or may cause irritation when in contact with the skin.<\/p>\n\n\n\n<p>However, a <a href=\"https:\/\/ntp.niehs.nih.gov\/ntp\/htdocs\/st_rpts\/tox074_rev.pdf\" target=\"_blank\" rel=\"noreferrer noopener\">cellulose toxicity study report<\/a> found that less than 0.1% of particles were small enough to be inhaled, and amounts of these particles were low at work sites.<\/p>\n\n\n\n<p>Similarly, there is little evidence to suggest that cellulose insulation causes lower respiratory health conditions, and there does not seem to be evidence to suggest that the chemicals in cellulose insulation cause cancer.<\/p>\n\n\n\n<p>So, while it is wise to be cautious when installing cellulose insulation (especially for those with skin sensitivities and asthma), there does not seem to be major cause for concern.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">How Does This Material Provide Insulation?<\/h3>\n\n\n\n<p>Paper is known to be a good insulator as the plant fibers trap air and prevent convection (heat flow through liquids and gases). Since cellulose insulation is made of paper fibers, it makes sense that it is a good insulator too.<\/p>\n\n\n\n<p>Cellulose also provides insulation by preventing the flow of heat from the inside of a building to the outside through conduction (heat flow through solid materials), by providing a barrier to the heat flow.<\/p>\n\n\n\n<p>This resistance to heat flow means that insulation helps your home to stay warm in the winter and cool in the summer.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Differentiating Between Cellulose and Asbestos<\/h2>\n\n\n\n<p>In contrast to cellulose, <a href=\"https:\/\/thetibble.com\/asbestos-what-why-dangerous\/\">asbestos is comprised of small fibrous silicate crystals<\/a>.<\/p>\n\n\n\n<p>Cellulose and asbestos can be difficult to distinguish visually. If you suspect that there is asbestos in your home, it is best to leave it undisturbed and contact a professional. &nbsp;<\/p>\n\n\n\n<p>Asbestos insulation is usually light brown or white in color but may also be greyish brown or silver gold.
