Product Information

Full details

The Gyproc ThermaLine PIR insulated plasterboard is an essential solution for homeowners, contractors, and DIYers looking to enhance the thermal efficiency of residential or commercial buildings. By combining a 12.5mm plasterboard with high-performance PIR foam, this product offers a dual-action approach of drylining and insulation in a single installation step, though users should note that the increased thickness compared to standard boards requires careful planning for window reveals and door frame depths.

FAQs

Can I use this board in a bathroom?

Yes, the integrated vapor control layers make it suitable for areas prone to moisture, provided all joints are properly sealed.

What is the total thickness of the board?

The board has a total thickness of 28mm, consisting of 12.5mm plasterboard and an integrated layer of PIR foam.

Can these boards be fixed directly to masonry?

Yes, they can be fixed to solid walls using a dot-and-dab adhesive method or mechanical fixings.

Is this product BBA approved?

Yes, Gyproc ThermaLine PIR is part of a BBA-approved system for thermal insulation.

Does the board contain harmful chemicals?

No, the product is completely CFC and HCFC-free.

Can I use this for ceiling applications?

Yes, it is suitable for both wall and ceiling installations to help improve the thermal efficiency of a room.

Troubleshooting

Board is cracking at the edges

Ensure the board is properly supported and not overtightened during mechanical fixing; check that the substrate is level.

Difficulty achieving smooth joints

Ensure the tapered edges are aligned correctly and use a high-quality joint filler and scrim tape for a seamless finish.

Condensation appearing behind the board

Verify that all joints and edges were sealed with vapor-resistant tape during installation to prevent air leakage.

Pros and Cons

Pros

Reduces labor time by combining lining and insulation in one application
Provides high thermal resistance with a relatively slim profile
Excellent moisture management via dual vapor control layers
Suitable for a variety of surfaces including walls, ceilings, and window reveals
CFC and HCFC-free construction

Cons

Increased thickness compared to non-insulated board requires adjustment to existing fixtures
Requires precise cutting to maintain insulation integrity
Heavier than standard plasterboard, necessitating careful handling

Setup, Compatibility & Care

For optimal results, ensure the background wall is sound, dry, and clean before installation. The boards can be installed using mechanical fixings or high-strength adhesive dabs depending on the substrate. Always ensure that joints are tightly butted together and sealed with appropriate vapor-resistant tape to maintain the continuity of the vapor control layer. When cutting the boards, use a fine-toothed saw or a sharp insulation knife to prevent tearing the foam core. Store the boards flat in a cool, dry area, protected from moisture and direct sunlight until you are ready to install.
