Celotex 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 if insulating material - ranging from simple polystyrene backing to our high performance, foil-backed PIR insulation.

All sheets of Celotex PL4000 are created with 12.5mm general purpose plasterboard, but different sizes of Celotex insulation are used to suit a variety of uses. Available in 5 different thicknesses:

25mm, 40mm, 50mm, 60mm, 75mm,

The sheet is laminated to a 12.5mm plasterboard, to create a total thickness that includes the 12.5mm sheet, eg:

25mm Celotex + 12.5mm Plasterboard = 37.5mm Celotex Plasterboard.

Celotex insulated plasterboard is designed for use in roof and internal wall applications. It is ideal for loft conversions applied below the rafters - usually in combination with other insulation to help achieve a specific u-value - or below joists in flat roofs.
