Cork bark being harvested from a cork oak tree — natural insulation material

Natural Thermal Insulation — Ireland

Natural Thermal Insulation for Irish Buildings

VIPEQ spray-applied cork coating — a certified, breathable and renewable natural insulation system for homes, buildings and retrofits across Ireland.

A Genuinely Natural Material

Cork — Renewable, Breathable and Naturally Insulating

Cork is the bark of the cork oak tree, harvested by hand every 9 years without harming the tree. It is one of the most sustainable building materials available — renewable, biodegradable, carbon-storing and naturally resistant to moisture, mould and temperature extremes.

VIPEQ uses natural cork in a spray-applied coating system that delivers thermal insulation, breathability and façade protection in a single application — without the bulk, disruption or environmental cost of synthetic board insulation.

Why Natural Insulation Matters in Ireland

Ireland's Buildings Need Breathable, Vapour-Permeable Systems

A large portion of Ireland's housing stock is solid-wall construction — stone, brick or block without a cavity. These buildings need insulation systems that allow moisture to pass through the wall fabric. Sealing them with impermeable materials can trap moisture inside the wall, causing damage, mould and structural issues.

Vapour-Open System

Cork is naturally vapour-permeable — allowing walls to breathe and moisture to escape rather than being trapped.

Raises Surface Temperature

Creates a thermal barrier that warms internal surfaces — reducing cold spots and condensation risk.

Condensation Control

Warmer wall surfaces mean less surface condensation — reducing mould growth in problem rooms.

Natural & Sustainable

Cork is renewable, biodegradable and carbon-storing — a lower environmental impact than synthetic foam insulation.

Flexible & Durable

Elastic cork coating moves with the building — no cracking under normal settlement or temperature changes.

Thin Build-Up

Millimetre-scale coating — no loss of floor area, no disruption to skirtings, reveals or architectural features.

"We had persistent condensation and mould on the north-facing bedroom wall for years. After VIPEQ Thermal Corkspray was applied, the wall stays noticeably warmer and we haven't had a single damp spot since."

Declan Murphy

Homeowner — Wicklow

"I had two rented terraced houses with bad exterior render — cracked, patchy and leaking in a couple of spots. The corkspray sorted the facade, improved the look completely, and the tenants have commented on the warmer walls."

Siobhán Brennan

Landlord — Cork

"Old stone cottage on the west coast — we were losing heat through the gable wall badly. The breathable corkspray was important to us as we didn't want to trap moisture. Very happy with the result."

Tom Gallagher

Homeowner — Mayo
