140mm EcoTherm Eco-Versal Insulation Boards are multi-purpose thermal solutions that can be used in both new and refurbished projects. These 140mm rigid polyisocyanurate (PIR) boards are made up of a core of fibre-free material stuck between two aluminium foil layers. EcoTherm 140mm insulation boards are versatile and can be used for floors, walls, ceilings, pitched roofs, and more. These 140mm EcoTherm insulation boards are second only to phenolic insulation for thermal efficiency. They have a thermal conductivity of just 0.022 W/mK. 140mm EcoTherm insulation boards are cost-effective and environmentally friendly, which makes them a good choice for reducing CO2 emissions. They are also highly versatile and can also be used on a variety of building projects.
