Built for walls that need to breathe.
Warm Walls is a four-layer system fixed dry against the inside of a solid wall. Each layer has one job — and together they move moisture forward, off the wall and out of the room, while holding the heat in.
Reformed cork, fixed dry
Waste Portuguese cork, bonded by its own natural suberin resin. It won't rot, and its high thermal resistance removes the cold bridging you'd get from timber or metal fixings — so the system performs evenly across the whole wall.
80 mm of breathing wool
Pure, hygroscopic sheep's wool (λ = 0.033) does the thermal work while actively buffering humidity — absorbing moisture when the air is damp and releasing it when it's dry. It's treated against infestation without harsh chemicals.
A surface that breathes
An air-open wood-wool board lets the room breathe into the wool behind it, driving vapour forward and preventing condensation from ever forming inside the wall. It's plastered and decorated to taste — an ordinary-looking room with extraordinary physics.
Heat-pump ready
Heating pipes can be nested behind the board, turning the whole wall into a gentle low-temperature radiator. It cuts the need for extra radiators when a home moves to a heat pump — the fabric and the heating, upgraded in one pass.
Give the room full access to the wool. Moisture is drawn from the wall, carried forward through the open boards, and removed by normal ventilation — so the wall dries instead of trapping water.

Survey & assess
We assess the building and run a tailored EPC — before any work is quoted.
Design & target
We design the build-up for your walls and confirm the EPC rating you'll reach.
Dry-fixed install
Our trained team fits the system in your occupied home — no wet plaster, minimal disruption.
Verify & certify
A post-works EPC confirms the result in writing — the outcome you were promised.
