EcoTherm Eco-Versal 30mm PIR Insulation boards are a multi-application thermal solution for use in both new builds and refurbishment projects and are often used to reduce thermal-bridging. These 30mm rigid polyisocyanurate (PIR) boards consist of a fibre free core sandwiched between two layers of aluminium foil. EcoTherm 30mm insulation boards can be used in a variety of applications, including floors, walls, ceilings and pitched roofs. Second only to phenolic insulation in terms of thermal efficiency, these 30mm insulation boards have a lambda value of just 0.022 W/mK. Good for reducing CO2 emissions, 30mm EcoTherm inuslation boards are a cost-effective, environmentally friendly insulation solution that are suitable for a wide range of building projects.
