PIR Insulation Board 1200 x 450 x 50 mm; 47.2 x 17.7 x 2 in, One Panel Covers 0.54m² (5.81 ft²), Rigid Thermal Panel with Aluminum Foil on Both Sides for Walls, Roofs, Floors and Sheds
Why we love it
- Excellent thermal insulation performance.
- Versatile for various applications.
- Lightweight and easy to handle.
Main Highlights
- Strong Thermal Performance – Built with rigid PIR (polyisocyanurate) foam and aluminium foil facings on both sides, the boards deliver excellent insulation with a declared thermal conductivity of λD: 0.022 W/(m·K) (EN 13165). The foil layer reflects radiant heat, helping reduce heat loss in winter and overheating in summer.
- Versatile Use Across Surfaces – Suitable for wall cavity insulation, flat roof insulation, floor upgrades, and shed insulation. Also used in DIY projects such as camper conversions and pet enclosures. Improves comfort in homes, lofts, garages, and outbuildings by keeping the indoor climate stable year-round.
- Lightweight and Easy to Handle – Each rigid insulation board measures 1200 x 450 x 50 mm (47.2" x 17.7" x 2") and weighs 1.1 lbs (0.5kg), and covers 0.54 m² (5.81 ft²). Easy for one person to carry, cut, and install, saving time and effort on home or outdoor projects.
- Quick to Cut and Fit – The rigid insulation foam can be trimmed with a sharp knife or fine saw for accurate sizing, while the foil face adds durability. Designed for hassle-free installation.
- Durable, Rigid and Reliable – A 100% CFC, HCFC, and HFC-free insulation board. This thick insulation board 50mm is resistant to moisture and tested for mechanical strength, providing long-lasting performance in building and renovation projects, including floor, roof and wall insulation. Fire safety tested to EN 13501-1 Class E.
