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.
Types of insulated plasterboard?
Insulation Wholesale supplies several types of insulated plasterboard with varied thicknesses, ranging from 25mm to 80mm.
- Ecotherm eco-liner insulated plasterboard: This is a fibre-free rigid polyisocyanurate insulate core glued to 12.5mm tapered-edge drywall plasterboard using adhesives. The two-in-one panel insulates and dry lines your walls in just one application.
- Recticel eurothane PL insulated plasterboard: Recticel Eurothane PL pairs high-performance insulation with plasterboard, making homes warmer with a sleek, easy-fit design.
- Celotex PIR insulated plasterboard: Suitable for use in roof and internal wall lining applications. Celotex Insulated Plasterboard is a high-performance, easy-to-install PIR insulation board with a paper facing, laminated to a piece of 12.5mm tapered-edge plasterboard
- Kingspan Kooltherm K118 insulated plasterboard: this provides superior performance compared to the other two insulated plasterboard. It also comes with a free-fibre rigid phenolic core. When it comes to rigid thermoset insulation materials, this insulation’s performance is unrivalled.
Benefits of insulated plasterboard
- Insulated gypsum boards are cheaper than similar materials. Buying insulated plasterboard online keeps the process simple and helps you compare options at affordable prices.
- Besides saving on bills, your home will be comfortable to live in. It remains warm in the winter and cool in the summer.
- Insulated thermal plasterboard is easy to handle and install. However, you would need additional hands, especially when cutting. Remember, it is delicate, and if handled carelessly, it can be damaged.
- Foam-backed plasterboard is free of Formaldehyde, HCFC, and CFC. So, it has little impact on the environment.
- Plasterboard with insulation offers excellent moisture resistance, helping keep your home dry, especially during the cold winter months.
- Offers versatility – with insulated plasterboard, a homeowner is not limited to one option. You have various options for size, colour, and thickness. You can choose whether to increase the thickness of your wall or keep it thin.
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.
When comparing brands and thicknesses, Insulation Wholesale helps you secure insulated plasterboard at affordable prices without compromising on performance.

FAQ
Where to buy insulated plasterboard?
You can buy insulated plasterboard online at Insulation Wholesale. We offer the widest choice of brands, thicknesses, and board types, along with bulk pricing for larger projects. We have project-ready UK stock ready for delivery straight to your site.
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).
