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.
