Black Mountain Natural Wool Insulation Roll

Black Mountain Sheep Wool Insulation

Black Mountain Black Mountain Sheep Wool Insulation is a general purpose natural wool insulation fiber product designed for use in a loft, rafter, internal wall, and inter-floor applications. Black Mountain Sheep Wool Insulation meets and surpass US building product standards for Thermal, Fire, Mold Resistance, and Structural performance.

Wool insulation is not only breathable but also able to absorb, retain and release moisture without affecting its thermal properties or performance. Wool insulation is ideal for breathable wall construction.

The manufacture of sheep wool insulation requires 90% less energy to manufacture than mineral wool insulation. In use, the durability and moisture control properties of wool allow for a higher level of performance and longevity. Retaining its insulating properties for the life of the building.

Environmental Information

The manufacture of sheep wool insulation requires 90 percent less energy to manufacture than mineral wool insulation. In use, the durability and moisture control properties of wool allow for a higher level of performance and longevity, retaining its insulating properties for the life of the building. Wool is naturally fire resistant and is treated with boron salts so as to heighten its vermin and insect resistance.

Ordering

Please use our Wool Insulation Quote form if ordering more than 3 rolls. We will provide you with an estimate that meets your needs.
These 24″ rolls are 22.5″ wide, designed to fit snugly between 24″-on-center framing members (studs or joists).  If your framing is 16″ on center then click here for our: 16″ wool insulation.

Advantages

  • Controls condensation, wool absorbs and releases moisture yet doesn’t lose it’s thermal performance, wool can in fact absorb up to 40 percent of its own weight and remain dry, to the touch.
  • Wool actually heats up when absorbing moisture by up to 45 degrees F, this increases the dew point temperature reducing the risk of condensation.
  • Wool absorbs harmful gasses, e.g. formaldehyde, and then locks them up permanently. Man made insulation emits gases.
  • A better insulator compared to glass fiber insulation, requiring 10 percent less thickness to achieve the same insulating factor.
  • Glass fiber thermal performance deteriorates dramatically when any moisture is present, wool’s performance is not affected.
  • Wool will last for the life of the building due to the resilience of wool, glass fiber may compact and require topping up after 10 years.
  • Wool is truly sustainable, a yearly clip of wool is available as a by-product of the livestock farming. Mineral wool depletes the world’s resources.
  • Wool is a “Carbon sink”, it actually locks up CO2, man-made pollutes CO2 during its manufacture.
  • Very low energy required in its manufacture, requiring 85 percent less energy compared to man- made products.
  • Biodegradable at the end of its life.
  • Safe to handle, no skin or respiratory problems typical of mineral wool.
  • Lastly sheep wool insulation is a product of choice from the consumers perspective, who continue to express their concerns with mineral wool insulation.

Fire Standards

Wool is naturally fire retardant, the material only chars since there is insufficient oxygen in the atmosphere to support combustion of wool. In the event of a fire, wool will not add to the fire risk and produces no toxic gases.

Applications

SheepRoll insulation is designed for use in new and existing buildings within the loft, rafter, internal wall, and inter-floor use. Wool insulation is ideal for dry lining on external walls and throughout all parts of wooden framed buildings.

Why Sheep Wool?

Sheep Wool is Warmer

  • Sheep wool insulation has a 10% greater insulating factor than many traditional glass fiber insulations.
  • Sheep wool is very hygroscopic; it is unique in that it generates significant heat as moisture is absorbed. The heat generated increases the dew point and thus reduces the risk of interstitial condensation.
  • Wool draws out moisture from the building and allows it to evaporate out of the building. It maintains its thermal performance even after absorbing up to 30% moisture. Traditional mineral wool thermal performance can deteriorate by up to 50% with only a few percentage points of moisture absorption leading to increased condensation.

Sheep Wool is Safer

  • Sheep wool is unique in its ability to absorb and lock up toxic gases (sulpher dioxide, nitrogen dioxide, and formaldehyde). Man made insulations and exhausts can emit these gases.
  • Wool is safe to handle and install requiring no protective clothing or equipment and exhibiting no skin or respiratory problems typically associated with mineral wool products (VOC / Carcinogen warnings)
  • Wool is a Carbon sink; it actually locks up CO2; man-made insulations can pollute CO2 during their manufacture.
  • Wool is naturally fire retardant resulting in higher ignition temperatures, low flame spreads, and ability to self extinguish.

Sheep Wool is Smarter

  • Sheep wool is truly sustainable: a yearly clip of wool is available as a by product of the livestock farming process.
  • Naturally resilient and strong, yet can be torn by hand across direction to facilitate faster install times.
  • Wool fiber has a natural spring which ensures that the insulation doesn’t compact over time (50+years) compared to mineral wool products that may compact and require topping after just 10 years.
  • Man made insulation currently can only be disposed of into landfills whereas sheep’s wool insulation is 100% biodegradable and can be composted at the end of its life.
  • Wool insulation requires very low energy to manufacture (embodied energy), requiring 85% less energy compared to man-made insulation products.
  • Black Mountain sheep’s wool insulation can potentially help earn several points in registered LEED projects.

    :

    “First do no harm” was the guiding principle we used in constructing a new home home back in 2010. After exploring all the alternatives we decided to utilize wool insulation for the floors, walls and ceiling of our house. We considered it an investment not only in our health but that of the planet as well. And, since we were doing the installation ourselves, it was important to be able to do this without worrying about compromising personal or planetary well-being either in the short term or over the long haul. There is not a day that goes by that we’re not thankful and convinced that we made the right decision. With all the fire retardants and chemical soup we encounter on a daily basis, our home is the one place we can feel safe, warm and surrounded by something truly healthy and good for us. Yes, it was a bit more expensive than the next best alternative, but we offset the cost by building a smaller dwelling which turned out to be, in total, the most economic and environmentally sustainable choice in ‘doing no harm’ that we think is possible.

    Thank you for making this product available, and for your exemplary customer service as well.

      Thank you for your passion and enthusiasm for sustainable building, and specifically for Sheep Wool Insulation! Natural Sheep Wool is our favorite insulation material, one of our favorite building materials in general. I would like to add that Sheep Wool Insulation moderates and handles moisture better than any other insulation material – especially important for a smaller, well-sealed house! We are currently featuring Black Mountain Sheep Wool Insulation rolls as part of our Fall-a-Wool-looza Fall Wool Winterization Sale. Local winterizers can visit our Wooly Wednesday Winterization Workshops to see and touch some Black Mountain Sheep Wool Insulation, and to discuss winterization issues, techniques, and products.

    Installed this in my tiny home a few years back. I recently ordered a couple more rolls to finish a tiny addition. I must say that this is a great product! And I will definitely order it again in the future. Thanks guys!

    Originally purchased because it’s fire retardant qualities and it’s ability to deal with moisture. I would buy it again due to how easy it is to install. It holds together very well and is easy to unroll and get into place. I love the fact that you literally are using a completely natural and sustainable product. Sheep are amazing!!!
