Gyproc Thermaline Plus Tapered Edge Plasterboard is a high-performance insulation solution for internal walls and ceilings. It measures 2.4m in length and 1.2m in width with a thickness of 27mm, providing enhanced thermal insulation to help improve energy efficiency in homes and buildings. It's an ideal choice for rooms where both insulation and a smooth, durable surface are required. This wallboard is bonded to an expanded polystyrene insulant, with integral vapour control provided by the product's closed-cell structure in the foam. It is a cost-effective thermal laminate for new and existing buildings requiring mid to high thermal performance levels. Insulation and vapour control in a single board boosts comfort and saves energy. The vapour barrier stops condensation and it is lightweight, making it easy to install. It is CFC and HCFC free, meaning it won't deplete the ozone layer. The 27mm thickness makes it perfect for window reveals.
