Trusted Insulation Specialists in Leeds & West Yorkshire
At GreenCork Ltd, we provide internal wall insulation in Leeds and West Yorkshire using a breathable cork-based coating system. We recommend this approach where external insulation is not suitable or where preserving the original façade is important. Our thin insulation coating is designed to improve wall surface temperature and help reduce condensation and mould without significantly reducing internal space.
Unlike plastering, which is purely decorative, our system improves thermal performance while remaining breathable and flexible. Unlike traditional board insulation that increases wall thickness and requires a multi-layer build-up, our thinner coating offers a practical solution with minimal disruption. We work across Leeds, Chapel Allerton, Headingley, Pudsey, Morley, Bradford, Wakefield, Halifax and wider West Yorkshire, ensuring every installation is suited to the local climate.
