Description
PIR insulated plasterboard for internal insulation
A room beside a cold outside wall may need insulation even when the façade cannot be changed. PIR insulated plasterboard combines insulation with a plasterboard finish on the room side. It provides a flat surface while making efficient use of the available depth, particularly in refurbishments where both thermal comfort and usable room area matter.
An insulated surface ready for decoration
The PIR core limits heat flow and the plasterboard forms the visible room-side face. Their factory bond simplifies planning and finishing. Wall colour, a smooth surface and furniture positions can be considered from the beginning. In a loft conversion, the same approach can give the slopes a uniform finish.
PIR’s low thermal conductivity allows insulation in a relatively thin layer. This can preserve space in a small study, bedroom or loft. Choose the internal insulation for the wall build-up and moisture conditions. A suitable assembly can reduce the sense of cold at outside walls. Select a facing appropriate to the interior. Once decorated, the insulation is concealed and the room can be finished in your chosen colours and style.
The insulation and room-side face arrive together, simplifying deliveries.
Large boards make it easier to plan a regular joint layout.
The plasterboard face is a familiar substrate for interior finishes.
Different insulation thicknesses allow the lining to fit the space at the wall.
Options for rooms being refurbished
PIR insulated plasterboard can line the inside of walls and suitable loft assemblies. Examples include a room converted into a home office or a refurbishment where the façade is being retained. It improves the thermal build-up and gives the room a new face. An even surface works with simple furniture and a shallow lining helps preserve passage width.
SteelProfil helps match PIR insulated plasterboard to the indoor conditions and scope of work. We offer first- and second-grade materials and selected lots from stock. We can compare current offers, product documentation and suitability for the proposed wall or loft lining.
