Ecotherm Insulated Plasterboard

Insulating has never been easier with EcoTherm Eco-Liner Insulated Plasterboard. EcoTherm Eco-Liner marries the thermal benefits of PIR with the structural benefits of plasterboard drylining. This easy-to-install thermal solution does a first-class job of upgrading thermal performance in internal wall applications - in both new builds and existing properties.

The 2.4m x 1.2m boards have low global warming potential (GWP) and showcase paper facings, with a thermal conductivity of just 0.022 W/m.K.

EcoTherm Eco-Liner 2400mm x 1200mm Applications

Insulate in a jiffy with the super convenient EcoTherm Eco-Liner plasterboard. The boards feature a fibre-free rigid polyisocyanurate (PIR) insulation core which is then bonded to a 12.5mm tapered edge gypsum plasterboard using proprietary gypsum adhesive. The tapered edge of the plaster makes it much easier to achieve a seamless finish between boards.

EcoTherm Eco-Liner Insulated Plasterboard is purposed for internal wall insulation such as solid walls, as well as cavity or timber frame walls in buildings old and new. Eco-Liner is suitable for both adhesive dot and dab application or mechanically fixed systems and ideal for refurbishing existing walls to a higher thermal performance.

Whilst the boards are usually installed on internal walls using the dot and dab method, Eco-Liner can also be fixed to the underside of pitched roof rafters to provide additional thermal protection in lofts.

EcoTherm Eco-Liner is ideal for the following applications:

  • Walls - solid, cavity or timber frame walls
  • Room-in-the-roof applications
  • Pitched roofs/Cold flat roofs
  • Both new build and renovations


EcoTherm Eco-Liner Specifications

Showcasing a 25mm rigid paper-faced PIR Insulation Board (with a thermal conductivity of 0.022 W/mK), and a 12.5mm plasterboard, EcoTherm is a user-oriented 2-in-1 solution that insulates and dry lines walls in a singular application. EcoTherm Eco-liner comprises a robust PIR fibre-free insulation core bonded to 12.5mm tapered edge gypsum plasterboard; enabling a smooth seamless finish using either skim coat plaster or seamless drywall jointing techniques (in accordance with manufacturer’s guidance).

With an excellent thermal conductivity value of 0.022 W/mK, these boards are the go-to solution for those looking to optimise the thermal performance of existing walls. The boards also respond quickly to heating systems whilst providing a cost-effective means of reducing CO2 emissions for compliance with Building Regulations.
The EcoTherm Eco-Liner range offers excellent thermal resistance in practical thicknesses - saving space internally.

Frequently Asked EcoTherm Eco-Liner Insulated Plasterboard Questions

What Are the Benefits of EcoTherm Eco-Liner Insulated Plasterboard?

The biggest benefit of EcoTherm Eco-Liner boards is that they dust off two jobs in one single operation. Each board combines the low-heat transfer properties of PIR with the structural integrity of plasterboards. All-in-one boards are perfect for people who do not have time for the traditional lath and plaster process for internal wall lining applications for quicker installation speed.

EcoTherm Eco-Liner Insulated Plasterboard Key Features:

Are EcoTherm Eco-Liner Plasterboards Flammable?

EcoTherm Eco-Liner thermal insulation boards are a B on the Euroclass scale with a B-s1,d0 rating. This basically means that they contribute to a fire to a very limited extent, their smoke production is very limited and they do not produce flaming droplets.

Are EcoTherm Eco-Liner Plasterboards Vapour-Resistant? 

Provided all joints between the product are sealed in accordance with manufacturer instructions, EcoTherm Eco-Liner can offer significant resistance to water vapour transmission.

How Should I Cut EcoTherm Eco-Liner Insulated Plasterboards?

The two-in-one nature makes these boards far stronger, but more difficult to cut.

You will need a saw to cut EcoTherm Eco-Liner with plasterboard. You can use an ordinary saw, but we recommend using a saw with fine teeth for a clean, precise cut. 

Always take the proper safety precautions when cutting insulation. We recommend cutting insulation in a clear, open space. You should always wear safety goggles and thick gloves.

How Should I Install EcoTherm Eco-Liner Insulated Plasterboards?

EcoTherm Eco-Liner insulated plasterboards are a popular choice because they are extremely easy to install and speed up installation times. The tapered edge plasterboard allows them to fit seamlessly to lots of different joists, frames, and rafters.

You can fit EcoTherm Eco-Liner plasterboards with industry-wide, standard practices. Direct bonding dot and dab (also known as drylining) is one of the most popular ways of installing plasterboards. You can install the plasterboard directly on top of a concrete or blockwork wall application. This process gains its name from the way that the plasterboard adhesive is pasted to the wall in even dots and dabs.

Some people use mechanically fixed installation techniques to secure insulated plasterboards to walls. More often than not, a galvanised mechanical anchor with a concave head can achieve your desired result. There are lots of different types of mechanical fixings that you can choose from.
