A wide range of eco-friendly insulation materials, carefully selected for their sustainability and effectiveness — from natural fibres to recycled options.
Natural and recycled options
Wood fibre, sheep's wool and recycled cellulose offer excellent thermal performance with high moisture buffering, which suits older, breathable buildings. Mineral wool made with a high recycled content gives strong fire performance and acoustic benefits at a competitive price.
Choosing the right material
The right material depends on wall build-up, moisture risk, fire requirements and budget. We explain the trade-offs in plain English and never specify a board simply because it is the cheapest — the wrong choice can trap moisture and cause problems years later.
Responsible sourcing
We buy from established UK suppliers with third-party certification and full technical support, so every system is covered by manufacturer guarantees and installed exactly to specification.
Frequently asked
Are natural materials as effective as synthetic boards?
For most applications yes — they may need slightly more thickness, but they handle moisture better and are far kinder environmentally.
