Aerogel and Rainscreen Insulation
Products like the Spacetherm A1 Blanket and K-Roc Rainscreen Slab offer advanced insulation solutions. These are particularly well-suited for high-performance requirements, like in buildings where space is limited or where superior thermal performance is needed.
PIR Insulation Boards
Unilin's Thin-R PIR boards, available in various thicknesses, are a popular choice for thermal insulation in floors, walls, and roofs. Their rigid structure and excellent thermal properties make them suitable for both new builds and renovations.
