You don&rsquo;t have to update your insulation with whatever type was first installed. <\/p>\n\n\n\n<p>The freedom to choose fiberglass over cellulose or vice versa means that you can control the additional benefits. I say additional benefits because you have to install enough of either to achieve the minimum required R-value, so it comes down to the bonus features. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Advantages<\/h3>\n\n\n\n<p>If you currently have fiberglass insulation, you can install cellulose over it in order to benefit from the greater ability of cellulose to <a href=\"https:\/\/thetibble.com\/insulation-help-sound\/\" data-type=\"post\" data-id=\"23274\">block out sounds<\/a>.<\/p>\n\n\n\n<p>This can bring peace of mind that your neighbors won&rsquo;t be able to hear you and it can also block out the noise of traffic, nearby construction, barking dogs, etc.<\/p>\n\n\n\n<p>Mixing the two insulation types is going to be a lot cheaper and time saving than if you were to remove the old insulation to replace it with the new one of your choice.<\/p>\n\n\n\n<p>Typically, fiberglass is slightly cheaper than cellulose insulation, which means that if you already have cellulose, you can top up your insulation with a cheaper option. In addition, if you have fiberglass but you come across a really good deal for cellulose, you can take advantage of this special price. <\/p>\n\n\n\n<p>Cellulose is more vulnerable to water, so if your insulation gets wet, you might be able to separate the majority of the material in the layers and <a href=\"https:\/\/thetibble.com\/wet-insulation-will-dry-all-types\/\" data-type=\"post\" data-id=\"29383\">dry out the fiberglass<\/a>, saving a good chunk of your insulation and lowering the cost of replacement.  <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Issues<\/h3>\n\n\n\n<p>Cellulose is denser than fiberglass, which means that per inch, it is going to be heavier.<\/p>\n\n\n\n<p>When you install cellulose over fiberglass, there is a risk of accelerated settling, which means that you will have top up your insulation again sooner. However, it is more likely to be a difference of a year or two as opposed to halving the life of the insulation.<\/p>\n\n\n\n<p>Blowing one type of insulation over another type of blown insulation can lead to uneven settling if more cellulose ends up over one part of the fiberglass than others.<\/p>\n\n\n\n<p>This way of adding insulation also means less control over the final R-value. Cellulose has a slightly higher inherent R-value, so if one part has a greater ratio of fiberglass to cellulose, you end up with a lower R-value in that area. This can happen even when you install the correct amount of insulation.<\/p>\n\n\n\n<p>You cannot install new insulation over old insulation if there is a problem with the old insulation, like <a href=\"https:\/\/thetibble.com\/mold-grow-wet-insulation\/\" data-type=\"post\" data-id=\"29363\">mold<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Mixing Method 2<\/h2>\n\n\n\n<p>The second way that cellulose and fiberglass can be mixed is to mix bags of cellulose with bags of fiberglass before 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\/2023\/03\/Fiberglass-and-cellulose-insulation.jpg\" alt=\"Fiberglass and cellulose insulation.jpg\" class=\"wp-image-31320\" srcset=\"https:\/\/thetibble.com\/wp-content\/uploads\/2023\/03\/Fiberglass-and-cellulose-insulation.jpg 1000w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/03\/Fiberglass-and-cellulose-insulation-300x219.jpg 300w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/03\/Fiberglass-and-cellulose-insulation-768x560.jpg 768w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/03\/Fiberglass-and-cellulose-insulation-960x700.jpg 960w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/03\/Fiberglass-and-cellulose-insulation-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\/Fiberglass-and-cellulose-insulation.jpg.webp\" alt=\"Fiberglass and cellulose insulation.jpg\" class=\"wp-image-31320 lazyload\" srcset=\"https:\/\/thetibble.com\/wp-content\/uploads\/2023\/03\/Fiberglass-and-cellulose-insulation.jpg.webp 1000w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/03\/Fiberglass-and-cellulose-insulation-300x219.jpg.webp 300w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/03\/Fiberglass-and-cellulose-insulation-768x560.jpg.webp 768w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/03\/Fiberglass-and-cellulose-insulation-960x700.jpg.webp 960w, https:\/\/thetibble.com\/wp-content\/uploads\/2023\/03\/Fiberglass-and-cellulose-insulation-150x109.jpg.webp 150w\" sizes=\"(max-width: 760px) calc(100vw - 24px), 720px\" data-pin-media=\"https:\/\/thetibble.com\/wp-content\/uploads\/2023\/03\/Fiberglass-and-cellulose-insulation.jpg\" id=\"mv-trellis-img-3\" data-trellis-processed=\"1\"><\/figure>\n\n\n\n<p>I have not heard of anyone using this method. This is because, while there are advantages, there are more issues. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Advantages<\/h3>\n\n\n\n<p>As with the previous method, by mixing the bags together, you can cut your costs a bit but still get good insulation and some bonus soundproofing. <\/p>\n\n\n\n<p>Unlike the first method, however, you can ensure a much more even coverage by mixing the materials together at the start.<\/p>\n\n\n\n<p>In addition, the issue of accelerated settling is much lower because the cellulose is not layered on top of the fiberglass. Instead, it is spread evenly throughout the full thickness of the insulation. This is not to say that the settling won&rsquo;t happen quicker, it just means that it is slower and\/or less likely. <\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Issues<\/h3>\n\n\n\n<p>Mixing cellulose and fiberglass before installation is going to be a tedious and messy task, particularly if you are trying to get a proper ratio and distribution.<\/p>\n\n\n\n<p>Furthermore, you increase your exposure to the insulation materials. While they may not be terribly dangerous, they are also not completely harmless.  <\/p>\n\n\n\n<p>Because cellulose is more vulnerable to moisture, if your insulation gets wet, you cannot isolate the beyond-help cellulose from the can-be-saved fiberglass.
