SuperFOIL Insulation

SuperFOIL is a UK-based manufacturer specialising in high-performance multi-foil insulation systems designed for modern construction and retrofit applications. Founded in 1997 as part of the parent company Boulder Developments Ltd, the business focuses on delivering insulation solutions that combine thermal performance, radiant barrier effects and vapour control in one product. Their product range features lightweight, space-saving rolls and panels suitable for roofs, walls, floors and unique builds where thickness is limited. Each system offers a “3-in-1” performance: thermal insulation, radiant barrier and built-in vapour control layer. SuperFOIL’s commitment to quality is backed by testing to BS EN ISO standards and certification by the British Board of Agrément (BBA) for UK use. The company emphasises sustainable manufacturing, using up to 40 % recycled materials and offering complete support for U-Value calculation and build-up design. By offering efficient, versatile insulation with engineering support and credible certification, SuperFOIL delivers practical solutions for performance-driven projects in both new build and renovation markets.
