What Is Cork Plaster Insulation?
Cork plaster insulation is a thin, seamless, and sustainable solution for upgrading internal walls.
Made from natural cork, the product is mould resistant, breathable, and provides excellent thermal and acoustic performance. It’s ideal for retrofits, conservation projects, and new builds alike.
Internal wall insulation is a method of improving a building’s energy efficiency by adding an insulating layer to the buildings inside, outer wall's. It helps keep heat in, reduces cold spots and condensation, and can cut down on noise, due to the natural benefits of cork. Cork has much more benefits than just thermal qualities.
What is AeroCork™?
AeroCork™ is a high-performance cork-based insulating plaster, enhanced with aerogel for maximum thermal efficiency.
It is applied directly to internal walls to create a seamless, breathable insulating layer that improves comfort and reduces heat loss.
