EcoTherm Eco-Versal 50mm PIR Insulation Boards are multi-purpose thermal solutions that can be used in both new and refurbishment projects. These 50mm rigid polyisocyanurate (PIR) boards are comprised of a core of fibre-free rigid foam sandwiched between two layers of aluminium foil. EcoTherm 50mm insulation boards are highly versatile and can be used for floors, walls, ceilings, pitched roofs, and more. These 50mm EcoTherm insulation boards are second only to phenolic insulation for thermal efficiency. They have a thermal conductivity of just 0.022 W/mK. 50m EcoTherm insulation boards are a cost-effective and environmentally friendly solution, making them a good choice for reducing CO2 emissions. They are also suitable for use in a wide range of building projects.
