Product Information

Full details

The Celotex PL4050 Insulated Plasterboard is an essential solution for contractors and DIY enthusiasts looking to improve thermal efficiency in new builds or refurbishment projects. By combining high-performance PIR insulation with a standard 12.5mm plasterboard in one unit, it significantly reduces installation time and labor costs. While it offers excellent thermal performance with a conductivity of 0.022 W/mK, users should note that its 62.5mm overall thickness requires adequate space for installation, particularly in tight wall cavities.

FAQs

What are the dimensions of the PL4050 board?

Each board measures 2400mm in length by 1200mm in width, with a total thickness of 62.5mm.

Can I use these boards in a bathroom?

While the plasterboard layer is standard, ensure it is treated with a moisture-resistant coating or tanking system if installed in high-humidity areas.

Is the plasterboard face ready for painting?

Yes, but you should finish the joints with tape and jointing compound and apply a mist coat before final painting.

Does this product require special tools for cutting?

No, it can be cut using a standard fine-toothed hand saw or a sharp insulation knife.

Is the insulation component safe to handle?

It is generally safe, but wearing gloves and a dust mask is recommended to prevent irritation from dust during the cutting process.

Are these boards fire rated?

Celotex boards are designed to meet building regulations, but you should consult the specific BBA certificate for detailed fire performance classifications.

Troubleshooting

Board cracking during installation

Ensure the wall surface is level; avoid applying excessive force on high spots of the masonry.

Adhesive failing to bond

Check that the substrate is not dusty or damp; remove debris before re-applying adhesive.

Setup, Compatibility & Care

Installation

Ensure the substrate is clean, dry, and free of loose debris.
When using direct bonding, apply adhesive dabs evenly to the back of the board or the wall surface.
For mechanical fixing, ensure screws are long enough to penetrate the substrate adequately without damaging the PIR core.
Stagger joints to maintain structural integrity.

Suitable for timber frames, masonry, and steel stud wall systems.

Care and Storage

Store boards flat in a clean, dry area, preferably indoors.
Keep boards off the ground using pallets to prevent moisture damage.
