EcoTherm Eco-Versal 40mm PIR Insulation Boards are multi-purpose thermal solutions that can be used in both new and refurbishment projects. They are also useful in reducing cold-bridging. These 40mm rigid polyisocyanurate (PIR) boards are made up of a core of fibre-free material sandwiched between two layers of aluminium foil. EcoTherm 40mm insulation boards are versatile and can be used for floors, walls, ceilings, pitched roofs, and more. These 40mm EcoTherm insulation boards are second only to phenolic insulation for thermal efficiency. They have a thermal conductivity value of just 0.022 W/mK. 40mm EcoTherm insulation boards are cost-effective and environmentally friendly, which makes them a good choice for reducing CO2 emissions. They can also be used in a variety of building projects.
