52.5mm Speedline insulated plasterboards deliver superior thermal performance for residential and commercial properties. These boards feature a fibre-free rigid polyisocyanurate (40mm PIR) core bonded to 12.5mm plasterboard at manufacture. This dual-function design combines thermal insulation with dry-lining in one product, reducing installation time and labour costs.
Environmental credentials are a key strength of this product. These boards carry Zero Ozone Depletion Potential (ODP) and Zero Global Warming Potential (GWP), with no CFC or HCFC content, making them an eco-conscious choice for sustainable building projects.
Lightweight construction ensures straightforward handling, cutting, and installation. A fine-toothed saw is recommended for cutting these insulation boards, with a wooden plank or ruler serving as a reliable cutting guide to maintain accuracy and stability during the process.
