What we do
Natural Smart Fibre
Wool Insulation Wales manufactures high-performance Welsh wool insulation for people who want buildings that are healthier, more sustainable, and built to last.
We help architects, homeowners and heritage specialists create breathable, natural, comfortable spaces without compromising on performance.
Warm, breathable and moisture-balancing insulation. 100% wool and manufactured in the UK
Natural insulation that puts the building first
Wool Insulation Wales exists for people and projects where standard insulation simply isn’t good enough, where breathability, sustainability, occupant wellbeing and long-term building health genuinely matter.
We manufacture high-quality wool insulation in Wales, using locally sourced materials and modern processes.
Unlike mass-produced synthetic insulation, wool offers natural moisture control, breathability, acoustic performance, longevity and fire resistance, all without the environmental cost.
Our mission is simple:
To help people insulate buildings properly - in a way that respects the structure, protects the occupants, and supports a sustainable future.
We don’t compete on being the cheapest.
We compete on being right for the right buildings, for the right reasons.
Beyond Buildings
Wool isn't just for insulation
We're applying the same natural fibre technology to restore landscapes and support environmental recovery.
