Wall insulation

EcoTherm's thermal rigid insulation boards are an ideal solution to insulating cavity walls, internal walls and timber frame walls.

The excellent thermal performance of the boards means less thickness (approx half) is required when compared to traditional forms of insulation - saving space internally where it matters the most.  Meet thermal standards and Building Regulations with minimal thickness in walls without the need to alter the thickness of the construction or your chosen method.

There is always a practical limitation to the width of a cavity in buildings. This limitation requires the thinnest possible insulation material to provide an acceptable cavity, which will inhibit the passage of rainwater to the inner skin. This is in addition to providing sufficient thermal resistance to allow cavity wall insulation to meet the building regulations. EcoTherm® cavity wall insulation solutions do all this and more.


Eco-Cavity wall insulation boards are ideal for masonry walls. They achieve high levels of thermal performance for thinner constructions whilst maintaining a clear residual air gap; effective protection against driving rain, particularly in coastal and exposed locations.

The boards are conveniently sized to co-ordinate with brick and block dimensions and to allow the insertion of wall ties at the appropriate spacing.

Eco-Cavity Full Fill

Eco-Cavity Full Fill allows users to optimise the full cavity with high performing thermal insulation, meaning U-values and Building Regulations can be met without altering standard construction designs. Eco-Cavity Full Fill prevents the need to increase cavity space and overall wall width to accommodate larger thicknesses of traditional insulation materials.

The board's tongue and groove edges ensure a continuous layer of insulation, increases protection from wind driven rain and also aids installation.
EcoTherm offers Eco-Liner, an insulated plasterboard that enables internal wall insulation in one easy application without impacting on the interior space. This internal insulation is ideal for upgrading the thermal performance of existing buildings by insulating from the inside. It can be used internally on solid walls, cavity walls or to line timber frame walls, but also to line the underside of pitched roof rafters to create a room in the roof.


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. 

By using Eco-Liner homeowners will improve the thermal performance of their walls. The boards also respond quickly to heating systems and provide a cost effective means of reducing CO2 emissions for compliance with Building Regulations. 

Applications: Internal walls; Pitched roofs/Cold flat roofs and; Room in a roof
When it comes to building lightweight, energy efficient structures, timber frame is at the top of the list.  EcoTherm's foil faced thermal insulation Eco-Versal or Eco-Protect are ideal for insulating a timber frame structure, whether it is assembled on or off site.

Firstly, the excellent thermal performance of EcoTherm's PIR insulation will keep the wall thickness to a minimum but still help reach Building Regulations with ease. By keeping the walls to a reasonable thickness the internal space can be maximised. Also, the rigid boards can be simply and easily cut to fit between and over studs. The insulation boards will not rot, sag or decay and will therefore continue to deliver designed insulation values throughout the lifetime of the building.


Suitable for use in between and over the studs of timber frame walls in new build or for upgrading the thermal performance of existing walls. Eco-Versal can also be used internally on solid or cavity walls to upgrade their thermal performance. The excellent thermal performance of EcoTherm's PIR insulation will keep the wall thickness to a minimum and provide a cost effective means of reducing CO2 emissions and compliance with Building Regulations/Standards.

Universal solution for insulating walls, floors, pitched roofs, dormer cheeks and ceilings. It is ideal for insulating timber frame walls and can also be used to insulate solid walls internally.
