Application: The 62.5mm insulated plasterboard is suitable for internal wall insulation across solid, cavity, and timber frame constructions in new and refurbished buildings. It also performs effectively as pitched roof insulation.
Key benefits of Eco-Liner include its integrated 2-in-1 insulation and drylining capability, high-performance rigid polyisocyanurate 50mm PIR insulation board core with tapered edge 12.5mm gypsum plasterboard, compatibility with room-in-the-roof applications, walls and cold flat roofs, and exceptional thermal performance with 0.022 W/mK conductivity.
The 62.5mm Ecotherm achieves European Classification (Euroclass) B-s1,d0 when assessed under EN 13501-1:2018, the standard for fire classification of construction products and building elements based on reaction to fire testing.
The insulation core delivers thermal conductivity of 0.022 W/mK, whilst the 12.5mm gypsum plasterboard component achieves 0.19 W/mK, providing excellent combined thermal resistance.
When properly installed, 62.5mm Ecotherm Eco-Liner offers indefinite service life. Longevity depends on installation method, structural support quality, and environmental conditions. This insulated plasterboard is unsuitable for use as a damp-proof barrier or in persistently damp or humid environments. Careful attention to application techniques and usage conditions ensures optimal performance and durability.
