How to install insulated plasterboard?

Get the surface ready – Should be dry and dirt-free. Plan your layout – Measure the wall and mark board positions, including cut-outs for sockets and switches. Doing a dry run reduces waste. Fit and anchor the boards – Use the correct fixing method for the wall type. Seal, skim, seal – Apply joint tape in all seams, skim as needed, and seal the edges with an appropriate sealant. Finish – Give the joints time to set, then plaster, paint, or apply another decorative method to the surface. Some boards – especially acoustic or fire-rated types – may have additional manufacturer-specific instructions. Check to confirm before installing.

How to cut insulated plasterboard?

Use a utility knife to score the surface, then snap the plasterboard along the scored line. With a handsaw or insulation knife positioned at one end of the board, slice through the material. Trim the edges for a perfect fit.

Can you dab insulated plasterboard?

Yes, you can use the dot-and-dab application method on insulated plasterboard. Dab the adhesive in a tight, continuous pattern around the board’s edges. Add extra dabs across the centre to prevent gaps behind the board. Some situations call for a sturdier fixing mechanism, for example: Walls that require a vapour barrier Areas prone to damp Spaces that require strict fire compliance These need mechanical fixings or a frame system to secure them properly.

Which insulated plasterboard is best?

The “best” board depends on project needs: PIR boards – Slim, high-performance, and space-saving. Best for walls, floors, and roofs. Phenolic boards – Extremely efficient per millimetre. Suitable for high thermal targets but more costly. Moisture-resistant boards – Best option for surfaces regularly exposed to moisture (such as kitchens, bathrooms, utility areas).
