highlights

Key features of Eco-Liner include a dual-purpose system delivering both insulation and drylining in a single installation, a high-performance rigid polyisocyanurate 25mm PIR insulation Board core with a tapered edge 12.5mm gypsum plasterboard, compatibility with room-in-the-roof applications, walls, and cold flat roofs, and outstanding thermal performance with a low conductivity of 0.022 W/mK.

Fire Performance

37.5mm Ecotherm achieves a European Classification (Euroclass) of B-s1,d0 when classified according to EN 13501-1:2018, the standard for fire classification of construction products and building elements based on reaction to fire tests.

Thermal Performance

The thermal conductivity (lambda/λ - value) of Eco-Liner's 37.5mm insulation core is 0.022 W/mK, whilst the 12.5 mm gypsum plasterboard component achieves a thermal conductivity of 0.19 W/mK.

Durability

When properly installed, 37.5mm Ecotherm Eco-Liner is engineered for indefinite service life. Product durability depends on installation method, supporting structure quality, and usage conditions. Note that the 37.5mm insulated plasterboard is unsuitable as a dampness isolator or in persistently damp or humid environments. Careful attention to application methods and environmental conditions is critical for optimal performance and longevity.
