Eco-Liner - Insulated Plasterboard

Eco-Liner insulated plasterboard is suitable for internal wall insulation for solid, cavity or timber frame walls within new and existing properties.

The 2 in 1 board insulates and dry lines walls in one application.  Eco-Liner is ideal for refurbishing existing buildings to a higher thermal performance. 

See how easy Eco-Liner is to install by watching our step by step guidance videos for dot and dab adhesive or mechanical fix application.


One board, two application methods: Eco-Liner is suitable for both adhesive dot and dab application or mechanically fixed systems.

Adding additional insulation by using Eco-Liner will improve the thermal performance of walls.  The boards also respond quickly to heating systems and provide a cost effective means of reducing CO2 emissions for compliance with Building Regulations. Eco-Liner is ideal for:

  • Internal walls
  • Pitched roofs/Cold flat roofs
  • Room in the roof applications

EcoTherm recommend that Eco-Liner is installed in line with good building practices for insulation, such as the Energy Saving Trust CE17 – Internal Wall Insulation Best Practice Guide. The Eco-Liner product can assist house owners, landlords and local authorities to improve the thermal performance of the dwelling in order to comply with HHSRS – Housing Health and Safety Rating System.  EcoTherm Eco-Liner has been approved as an Energy Saving Trust Listed product.
