sheep wool insulation vs fiberglass

Sheep wool is the BEST non-toxic insulation for your camper van conversion– it’s sustainable, naturally fire-resistant, breathable, doesn’t retain moisture, easy to install, and it’s literally sheep wool, so there are no toxic chemicals. While these materials are considered safe by institutes such as the U.S. National Toxicology Program and the International Agency for Research on Cancer, they do contain synthetic, hairlike fibers that can break off and become airborne during installation. Wool is composed of proteins known as keratins. Since sheep’s wool contains moisture in each fiber, it doesn’t need the dangerous flame retardants that are added to synthetic insulation. The fact that it’s nontoxic and eco-friendly aren’t the only reasons that this kind of insulation is worth looking into, though. Renewable Insulation. FIBER GLASS & MINERAL WOOL VS. CELLULOSE INSULATION: COMPARING THE FACTS NO MATTER WHAT the building challenge, fiber glass and mineral wool insulation have the product variety, application flexibility and value to help satisfy every job’s demands. More recently, a blow-in product has been introduced to the market. On the other hand, some 73 percent of the wool coarser than 28 micron was evaluated to be highly resistant to compression. Wool’s scaled structure allows for absorption and retention of airborne dust. https://havelockwool.com/fiberglass-insulation-vs-wool-insulation Instead, we process high quality wool fibers through our proprietary manufacturing process. The fibers we use are a certain dynamic – we shear them from a specific breed of sheep best suited for insulation. This allows for condensation to be minimized as wool generates heat from energy, thus making it warm when wet. PURE WOOL INSULATION Improved Performance. Industry practitioners like to call it ‘green’ given a relatively accelerated level of recycled content. Absorbs sound – wool exceeds other forms of insulation as an acoustic buffer. Other forms of outdated insulation, like vermiculite and urea formaldehyde foam, are also harmful. No other type of insulation offers these unique capabilities. If you live in an older home and plan to upgrade your insulation, be sure to test for asbestos and, if it is present, enlist professional help to remove it safely. Havelock Wool offers both wool batt and blow-in insulation. Fiberglass offers an R-value of 2.2 to 2.7 per inch, while rock wool has an R-value of 3.0 to 3.3 per inch, making it a slightly better insulator than fiberglass, according to the U.S. … The molecular makeup of sheep’s wool is helical, which reduces airborne sound, surface noise, and sound transmission. Rolled insulation may take less time to install than batts if you have large areas to cover. If wool becomes inundated with moisture, the follicles within the fiber can hold up to a third of its weight. We don’t make our insulation from wool scraps. Appropriate training used to be somewhat of a norm, now spray trucks can be rented. I am left with trying to split fiberglass batts or consider a treated sheep wool alternative. PURE WOOL LIFE INSULATION insulation does not contain any harsh chemicals or odors and is the only 100% green natural wool insulation … ... Sheep’s wool. Fibreglass Batts – Like Sheep’s Wool and Down Feathers. For more than a century, most new homes were built with fiberglass insulation, but this can cause many health issues. Each wool fiber is composed of protein molecules (keratin) organized into five follicles. Wool’s moisture regain is comparatively high. We’d stick to its rigid products being installed on the exterior and leave the natural stuff for the breathable air. Affordable: Fiberglass Insulation We work exclusively with those who appreciate alternative building products and a healthier, more sustainable ecosystem. Don’t Put Your General Contractor or Installer in Charge of Your Health. No off-gassing – natural characteristics make our insulation devoid of harmful chemicals. Sheep wool insulation R-value equals or often surpasses that of other insulation materials. We source only the best fibers for use in our wool insulation. Cost: Fiberglass insulation costs 25 to 50 percent less than mineral wool. The sheep wool type is all-natural and more efficient than fiberglass. Rigid foam insulation consists of panels sold in 4-by-8-foot sheets in a variety of thicknesses from 1/4 to 2 … The former is benign while the latter comprises excessive energy use which is compounded with the need for extreme high heat to make an insulation product. With a noise reduction coefficient of 0.90 to 1.15, sheep’s wool insulation makes a supreme sound barrier for the home. Wool’s natural structure make it incredibly effective as an insulator. Given the inevitability that moisture will infiltrate an insulated cavity and cotton’s propensity to create mold and mildew means this product is a nice idea until pushed against real efficacy. Long lasting – inherent characteristics allow stated R-values to exceed other forms of insulation. Each wool fiber acts like a coiled spring: It elongates when extended and retracts when it’s released, which is why wool is highly resistant to breakage and tearing. Harmful chemicals are in your walls; wool filters the air and improves indoor air quality. The results of the pilot project indicate that, while sheep's wool insulation produced at a smaller, or artisanal scale shows some potential, scale of operation and volume of production need to be carefully considered in order to ensure long-term sustainability of the operation. Equally important, wool is a keratin and therefore will not support the growth of mold. On the other hand, the Fiberglass material has an R-value ranging from 2.2 to 2.7 per inch. … The stuff that keeps sheep warm can also be used to keep your home snug. As a result, they’re not ideal for floor insulation. Sheep’s wool insulation offers supreme durability due to its elasticity, and will keep a home toasty or cool for years to come.

Sheep’s wool insulation offers an R-13 to R-19 value, which is equal to or greater than most of its fiberglass, cellulose, and rockwool counterparts. Our views are here – read more. Fiberglass insulation (the pink stuff) consists of superfine woven and compressed glass fibers that are produced in mass and cut into rolls or “batts” of insulation. The removal of such a badge of (dis)honor occurred for reasons we don’t understand. Spray foam insulation is a chemical manufacturing facility that moves between job sites. During installation and before it cures completely, the material is especially dangerous due to the high level of VOCs that off-gas into the air. Sheep's wool insulation is presently over four times more costly than conventional fiberglass insulation. As the construction industry moves away from toxic materials and closer to eco-friendly materials, insulation has not been left out. Because of its semi-permeability, wool functions as a temperature regulator: it absorbs moisture from the atmosphere of greater humidity and releases it to the drier atmosphere. Our wool is >35 micron. By Alexa Erickson. R-value denotes resistance to heat flow. Wool insulation is made from sheep wool fibres that are either mechanically held together or bonded using between 5% and 15% recycled polyester adhesive to form insulating batts and rolls. They also contain formaldehyde, which is known to release volatile organic compounds (VOCs) into the air. These fibers effectively trap air, moisture and harmful chemicals. Battsalso t… If you're planning to build a new home or undertake an energy efficiency renovation, sheep wool insulation might be worth considering. Intelligent Insulation For Your Healthy Home. Cellulose insulation is blown-in and has gained a fair bit of traction given its low cost. The higher an insulation’s R-value, the greater its insulating power. Newspaper as an insulator conjures images of those who lost their way and no longer have a house to call home. The amino acids in wool irreversibly bond with formaldehyde, NOₓ and SO2 on a molecular level. The cleaner the insulation, the better the quality of indoor air.
