Pros and Cons of Wool Insulation

Sheep Wool as an Alternative Insulation

sheep wool insulation

A material that maintains its warmth, even when wet, wool has long been known for its superior insulating properties.

The crimped nature of wool fiber gives it superior loft. The loft creates millions of tiny air pockets and it is actually air that does most of the insulating. Trapping the air in pockets slows the transfer of temperature from one side of the wall to the other.

Wool insulation ticks all the boxes that make an insulation green while still delivering on R factor.

A fiber that is super efficient at trapping air while being completely natural, having unique moisture control mechanisms and requiring little energy input into its production.

It doesn't get much greener than that.

Advantages of Sheep Wool Insulation

  • Manages Moisture - Natural wool fibers can absorb and release 30% of their weight in moisture.
  • Non Flammable - Wool naturally extinguishes flame and does not support combustion
  • Air Quality - Not only does it not give off formaldehyde, nitrogen dioxide and sulphur dioxide; sheep's wool absorbs and breaks them down.
  • Stays Where You Put It - Wool insulation doesn't settle downward over the years.
  • Works When Wet - Wool does not lose its insulating properties when it gets wet.
  • No Glass Fibers - The product doesn't release glass fibers into the air and onto your skin.
  • Easy to Install - No special gear is required for the installation of wool.
  • Rapid Environmental Payback Wool requires 85% less energy to manufacture than traditional fiberglass. The product saves the amount of energy that was used to produce it in 15% of the time it takes for fiberglass to do so.

Disadvantages of Sheep Wool Insulation

  • Cost - An expensive alternative costing upwards of $15 per square meter (yard) of insulation.
  • Transport - Not locally available in many areas. Mostly available in the UK.

Wool may seem like an expensive alternative but cost is the only disadvantage of this type of insulation if it's available in your area. If you don't mind paying for the best, sheep's wool may be the option for you.
