Wool product information

Wool insulation

Wool insulation is a cost effective, flexible and safe option for insulating homes and buildings, providing a range of superior benefits and designed to meet the highest demands of traditional and modern construction.

Superior insulating ability

Wool is naturally designed to protect sheep in all weathers. It has the ability to trap air within the fibre, which makes it a naturally effective insulator.

British mountain breeds of sheep often have a fibre known as ‘kemp’ within the fleece, which is a bristly, coarse fibre designed to provide additional protection from poorer weather conditions in the mountainous areas of Britain. This type of wool is especially effective in trapping air in the hollow centre of the kemp fibres, so is a great choice for insulation.

Temperature regulating and breathable

Wool helps to regulate temperature naturally because it’s a breathable fibre, absorbing moisture when the atmosphere is damp and then releasing it when the atmosphere is drier. This is an important benefit since ventilation does not remove all moisture from the fabric of buildings, so breathability is an important factor in regulating moisture in building fabric.  

Wool also has a higher thermal mass, so is able to buffer heat to reduce summertime overheating.

Affordable

Wool insulation is priced competitively and its’ ability to provide superior insulation means that it quickly pays for itself, helping to reduce energy and fuel bills.

Fire resistant and safe to handle

Wool is naturally flame resistant and non-combustible, which means it’s considered one of the safest fibres for use in family homes. Wool is also safe to handle – gloves, eye protection and masks are not required.

Helps to purify the air

Wool is able to absorb a range of potentially harmful chemicals often found in the home. These substances, present in cleaning fragrances, paint, glue and furniture, become bound to the structure of the fibres, improving air quality.

Noise absorbing

The natural structure of wool and its ability to trap air also helps to absorb sound, limiting the transfer of vibrations and noise through floors, doors and walls, and performing better than many synthetic alternatives.
