Naturally Warm. Comfortably Cool. Quietly Sustainable.

Sisalwool is natural, low-carbon insulation that keeps your home comfortable year-round. Made from renewable fibres, it’s breathable, energy-efficient, and delivers Class A sound absorption without compromise.

Why Sisalwool?

Kinder to your home, and your hands

Sisalwool is soft to touch, safe to handle, and free from petrochemicals. It won’t make your skin itch like traditional fibreglass insulation.

Seasonally Adaptable

Its natural fibres trap heat in colder months and regulate moisture in warmer ones, so your home stays comfortable, all year round.

Older Homes Love It

Unlike synthetic insulation, Sisalwool is breathable. That means it works with solid stone or brick walls to reduce dampness and avoid trapped moisture.

Sustainable. Safe. Surprisingly snuggly.

There is actually nothing surprising about it. Just pure, natural materials, free from nasties and harmful irritants. So go ahead, squeeze it, snuggle it, snooze on it, smush it, even give it a cheeky sniff. We get it.
