What is insulated plasterboard?

Insulated plasterboard, also known as thermal plasterboard, is known as a separate product for its unique benefits that don’t come with traditional plasterboard solutions. These benefits include reduced time spent and costs on installation!  It typically consists of plasterboard, covered with a layer of insulation attached to it. As such, no need to spend time and extra costs on two separate products when installing it in the property.

What can insulated plasterboard be used for?

Typically insulated plasterboard can be used for partition walls or any internal wall. Not only because of their insulation benefits, but also the fact there can  be a short time between installation and decoration. Insulated plasterboard can also be used for:

  • Commercial projects
  • Domestic projects
  • New builds
  • refurbishments
  • Self builds

You can also upgrade cavity wall insulation with insulated plasterboard that adheres to masonry inner leaf or can be mechanically fixed to timber battens.
