Warmline PIR Insulated Plasterboard

Insulated plasterboard is a time saving and DIY friendly option for drylining and stud wall construction, comprised of a sheet of general-use plasterboard (such as wallboard) adhered to a sheet of insulating material - ranging from simple polystyrene backing to our high performance, foil-backed PIR insulation similar to Celotex.

For the perfect time-saving product, Warmline PIR is an innovative insulated plasterboard that combines the insulating and plasterboarding step. It consists of a sheet of PIR (Polyisocyanurate Foam) Insulation (similar to Celotex) bonded to a traditional wallboard plasterboard with a tapered edge. This is ideal for reducing the storage required ahead of construction, and reducing construction time.

Warmline PIR Insulated Plasterboard is sold in a range of thicknesses. As insulated plasterboard is often used in conjunction with other insulation materials to achieve a certain u-value, the thickness is typically selected in accordance with the target u-value. They are made by adhering standard sizes of PIR insulation board to a 12.5mm general purpose plasterboard, so the resulting thicknesses are:

37.5mm (25mm PIR board), 52.5mm (40mm PIR board), 62.5mm (50mm board) and 72.5mm (60mm PIR board).
