Internal Wall Insulation

Contact us

PIR insulation products are suitable for use as internal wall insulation, for both new build and refurbishment projects.  They offer one of the thinnest solutions available as a result of their superior thermal performance.

PIR boards are available for installation in a variety of ways, such as via the dot and dab or adhesive method or they can be mechanically fixed to wall battens.

PIR boards can be added to a project independently or as an insulated plasterboard.

This method of insulating a solid wall is appropriate where it is impractical to insulate externally for reasons of aesthetics or space. The thermal performance of PIR/PUR insulation products is maintained for the lifetime of the building.

Benefits of PIR/PUR Insulation for Internal Applications:

  • Superior thermal performance
  • Maintains thermal performance for lifetime of the building;
  • Insulation and dry lining in one application
  • Minimal cold bridging
  • Reduces the risk of water penetration;
  • Resistant to moisture ingress;
  • Lightweight and non-fibrous insulation

Manufacturers’ products will offer different benefits depending on the application. For full details users should refer to the manufacturer’s third party certification.
