Thermano GK-H2 insulated plasterboard | 120 mm PIR variant

A cold wall or an uninsulated loft lining can make a room uncomfortable. When work takes place indoors, space and ease of finishing also matter. PIR insulated plasterboard combines thermal insulation with the interior lining. SteelProfil can help select a board for the room and its intended wall or roof build-up.

PIR insulated plasterboard consists of a PIR insulation layer bonded to plasterboard. The installer handles them as a single unit, which helps organise work where access to a room is limited. After correct fixing and joint treatment the surface is ready for decoration.

The core’s thermal performance can save space in a small room, loft or narrow passage. Select the thickness for the complete wall or roof assembly. With internal insulation, the design also needs to consider vapour movement and temperatures within the layers under the conditions found in the building.

Use the board in wall and roof linings covered by the manufacturer’s instructions. Examples include converting a loft into a study, renovating a living room or dividing up an existing space. Each arrangement needs a suitable substrate and fixings. In a small loft, draw the finished lining to see how much room will remain for the bed or desk.

Set out sockets, lights and future fixtures before installing the boards. This lets you plan service penetrations, corners, ceiling junctions and reveals. Careful detailing helps maintain insulation continuity and produces a neat painted surface.

A newly lined wall can form the background for shelving, a desk or a bedroom. The insulation is concealed behind the finish and contributes to comfort in use. Coordinate insulation and decoration with the times when the room is available for work.

SteelProfil supplies first- and second-grade insulation, with selected materials in stock. For PIR insulated plasterboard we confirm the specific version, board size and lead time. We can compare current offers on other refurbishment materials as well, taking account of the room and the condition of each lot.

Send us the wall or roof-slope dimensions and describe the intended finish. We can compare the available boards and calculate the order. A suitable PIR laminate helps turn a cold, unfinished space into a room prepared for its new use, with improved comfort and a surface ready to decorate.
