Condensation Control
NatuWool, a sheep's wool insulation, effectively manages condensation by absorbing over 35% of its weight in moisture without compromising thermal performance. It is particularly suitable for timber frame structures, acting as a moisture buffer and protecting the building fabric.

Historic Properties
Natural insulation like NatuWool helps preserve older buildings by allowing them to breathe while maintaining thermal resistance, thus improving energy efficiency and indoor air quality.

Building Towards a Brighter Future
Black Mountain's factory produces NatuWool with over 90% wool content, using waste wool from the British sheep industry. This sustainable approach minimizes energy use and waste.

Ease of Application
NatuWool is safe to handle without protective gear and is available in rolls or batts, making it easy to install in various spaces. It can be applied over existing insulation, though a mask is recommended to avoid inhaling dust.

Environmental Impact
Sheep's wool is biodegradable and can be composted or incinerated for energy, unlike man-made mineral fibres that end up in landfills.

Indoor Air Quality
NatuWool absorbs harmful gases like formaldehyde, improving indoor air quality and reducing health risks.

Durability and Longevity
Sheep's wool fibres are resilient, maintaining their structure and thermal performance over time. NatuWool is resistant to compaction, ensuring long-term effectiveness.

Fire Standards
NatuWool meets Euro Class E fire performance standards, ensuring it is flame retardant.

Installation & Application
NatuWool is versatile for use in lofts, rafters, walls, and floors, particularly in timber frame structures.

Standards
NatuWool complies with thermal requirements in England, Wales, Scotland, and Northern Ireland.

Sizes Available
Standard roll and batt sizes are available, with special sizes upon request.

Performance & Technical Standards
NatuWool has a thermal conductivity of 0.039 W/mK, a density of 19kg/m³, and zero ozone depletion and global warming potential.

Thermal Performance
Thermal resistance and U values are provided for various thicknesses, ensuring effective insulation performance.
