The Power of Wool Insulation
Wool insulation, derived from sheep’s wool, is a natural and renewable resource.
Unlike synthetic insulations such as rockwool or fiberglass, which are manufactured using petrochemicals and require high energy inputs during production.
Wool insulation is inherently sustainable. Sheep, the source of wool, graze on grass, making wool a renewable and biodegradable material.
This aspect alone aligns well with the increasing demand for eco-conscious building materials. |

Thermal Performance and Energy Efficiency
One of the primary reasons homeowners opt for insulation is to improve energy efficiency and reduce heating and cooling costs.
Wool insulation excels in this regard. Its unique natural fibre structure allows it to trap air effectively, providing excellent thermal insulation properties. This means your home stays warmer in the winter and cooler in the summer, reducing the need for excessive heating or cooling. The fibres high heat capacity allows the insulation to absorb and store heat and release it much later in the day when the temperature cools.
As a result, homeowners can expect to see significant savings on their energy bills over time.

Durability and Longevity
Another advantage of wool insulation is its durability and longevity.
Unlike synthetic insulations, which may degrade over time and lose their effectiveness, wool fibers are naturally resilient and can maintain their insulating properties for decades.
This longevity not only ensures long-term cost savings but also reduces the need for frequent replacement, thus minimising waste and environmental impact. |
Health and Indoor Air Quality
Indoor air quality is a growing concern for many homeowners, particularly those with respiratory issues or allergies.
Unlike some synthetic insulations, which can emit harmful chemicals or irritants into the air, wool insulation is non-toxic and hypoallergenic. It does not off-gas volatile organic compounds (VOCs) or other harmful substances, making it a safer and healthier choice for indoor environments.
Additionally, wool insulation is breathable meaning the insulation can act as a humidity buffer, helping protect structural timber elements from moisture and to regulate humidity levels and prevent mold and mildew growth. Which is a common issue in poorly insulated homes and lead to the accumulation of harmful bacteria and dampness that can cause serious health issues, asthma and other respiratory problems. |

Why is wool fire safe?
Wool insulation is a much safer option for easier installation and fire resistance due to its naturally high nitrogen and water content.
Wool may be ignited if subjected to a significantly powerful heat source, but does not normally support the flame; instead, it will smoulder and char.
Wool’s cross-linked cell membrane structure will swell when heated to the point of combustion.
Forming an insulating layer that prevents the spread of the flames. |

How does wool muffle sound?
Wool’s efficacy in sound absorption stems from its natural fibre composition, featuring an irregular surface shape and density.
In comparison to even top-tier mineral fibre insulation products, wool insulation offers significantly enhanced sound-muffling capabilities.
Its unique structure allows it to trap and diffuse sound waves more efficiently, making it an ideal choice for homeowners seeking to minimise noise transmission within their living spaces.
Whether it’s reducing street noise, dampening echoes, or enhancing privacy between rooms, wool insulation stands out as a reliable solution for creating quieter and more comfortable environments. |
