EcoTherm Eco-Versal 90mm PIR Insulation Boards are versatile thermal solutions that can be used for both new and refurbished applications. These 90mm rigid polyisocyanurate (PIR) boards consist of a core made of fibre-free material stuck between layers of aluminium foil. EcoTherm 90mm insulation boards can be used on ceilings, floors, walls, and ceilings, as well as pitched roofs. These 90mm EcoTherm insulation boards are second only in thermal efficiency to phenolic insulation. They have a thermal conductivity value of just 0.022 W/mK. 90mm EcoTherm insulation boards are cost-effective and eco-friendly, making them an excellent choice to reduce CO2 emissions. They can be used in many building projects due to their versatility.
