What is Insulated Plasterboard?


During the manufacturing process, the rigid polyisocyanurate insulant core is glued to tapered edge plasterboard to produce a durable and cost-effective internal wall insulation, also known as insulated drylining. This type of plasterboard provides a perfect insulation solution that significantly increases the thermal performance of solid wall constructions reducing heat loss from buildings.

Use and Application of PIR Insulated Plasterboard.


The insulation boards are suitable for insulation of cavity walls, as well as for the frame walls without impacting the interior space. The internal insulation enables an upgrade of the thermal performance of the existing building insulating the property from the inside. The boards are compliant with Building regulations thanks to their ability to respond quickly to heating systems and provide cost-effective solutions for reducing CO2 emissions.
