Ecotherm Insulation Boards

EcoTherm insulation boards are rigid PIR (polyisocyanurate) boards engineered for high thermal performance across floors, walls, and roofs. Lightweight and easy to handle, these foil-faced boards are ideal for energy-efficient construction, offering excellent insulation values with minimal thickness—perfect for saving space without sacrificing performance.

EcoTherm’s product range includes solutions for solid floors, pitched roofs, and wall insulation, including partial-fill cavity wall applications. The boards are designed to slot easily between wall ties and can also be used in timber-frame builds or beneath screed in flooring systems. Thanks to their aluminium foil facings, they act as vapour control layers too—adding moisture resistance to thermal performance.

Whether you're retrofitting a loft or working on a large new-build development, Insulation UK stocks a wide range of EcoTherm PIR insulation boards in various sizes and thicknesses. Offering thermal conductivity as low as 0.022 W/m·K, EcoTherm is a trusted choice for meeting building regs and reducing energy loss across the envelope.
