50mm PIR Cavity Insulation Board 1200 x 450mm is a rigid thermal insulation board designed for use within suitable cavity wall construction. The compact 1200 x 450mm board size makes the insulation straightforward to handle and position during installation, while the 50mm thickness provides a practical solution for cavity insulation requirements in new build, extension and renovation projects. PIR insulation provides high levels of thermal performance relative to its thickness, making it widely used where effective insulation is required within a limited construction depth.
