Insulated Plasterboard

Insulated plasterboard is an excellent way to minimise labour costs on a renovation/new build project and save time. Insulation Wholesale offers quality thermal plasterboard products from reputable brands such as Kingspan, Celotex, British Gypsum, Mannok, Unilin, and Recticel.

The products are available in different thicknesses and sizes, and you can also choose the insulation material and finish. Insulated plasterboard is commonly installed on internal walls to improve the wall’s ability to retain heat without adding significant wall depth.

What Is Insulated Plasterboard?

Insulated plasterboard (simply plasterboard with insulation) is a building material consisting of a gypsum board pre-bonded to insulation material. The thickness and size of the plasterboard depend on the grade of the insulation bonded to it.

• Plasterboard with insulation offers excellent moisture resistance, helping keep your home dry, especially during the cold winter months.

What Is Insulated Plasterboard Used For?

Gypsum board comes in handy when you want to line internal walls, typically, brick walls, in cases where both dry-lining and insulation are required.

Drywall insulation is inexpensive and takes little time to install compared to traditional insulation or dry-lining method, and can be the best alternative to conventional insulation material and foil-faced gypsum board.

Thermal Plasterboard Thickness

The thickness of thermal plasterboards varies significantly depending on the pre-bonded insulator. However, the thickness usually starts from 25mm to 80.5mm.

You need to consider the thickness depending on the type of project you want to do. For instance, if you don’t want to reduce your room’s size when insulating the walls, you should opt for a thin insulated plasterboard. That will save you space in your room compared to installing thick insulation.

What Are the Prices of Insulated Plasterboards?

Various aspects dictate the price of thermal plasterboard. The prices will usually vary depending on the brand, plasterboard type, thickness, and length.

Since insulation board with plasterboard has a wide array of applications from roofs, ceilings, and wall linings, it is essential to look for the best price offers, especially if you are operating with a shoestring budget.

How to install insulated plasterboard?

1. Get the surface ready – Should be dry and dirt-free.
2. Plan your layout – Measure the wall and mark board positions, including cut-outs for sockets and switches. Doing a dry run reduces waste.
3. Fit and anchor the boards – Use the correct fixing method for the wall type.
4. Seal, skim, seal – Apply joint tape in all seams, skim as needed, and seal the edges with an appropriate sealant.
5. 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).
