Product Information
Full details
This 22mm Thermal Basic EPS Insulated Plasterboard is ideal for homeowners and contractors looking to improve the thermal efficiency of internal walls and ceilings in refurbishment projects. By combining a 9.5mm plasterboard with high-performance expanded polystyrene (EPS), it provides an effective barrier against heat loss while maintaining a slim profile that saves valuable room space; however, users should note that the board is primarily for thermal insulation and does not provide structural load-bearing capabilities.

FAQs
Can I use this board in a bathroom?
This board is designed for general drylining. While it resists moisture better than untreated materials, it is recommended to use moisture-resistant variants in high-humidity areas like showers.
Is this board suitable for ceiling insulation?
Yes, it is effective for insulating ceilings, provided that the fixing method complies with building regulations for overhead applications.
Do I need a vapor barrier with this board?
Depending on your local building regulations and the existing wall construction, a separate vapor control layer may be required. Always consult a building professional.
What is the total thickness of the board?
The board has a total thickness of 22mm, which consists of 9.5mm of plasterboard and the integrated EPS insulation backing.
Can I paint directly onto the board?
Yes, once the joints are filled and sanded smooth, the board can be primed and painted just like standard plasterboard.
Troubleshooting
Cracking at joints after installation
Ensure joints are properly taped with mesh or paper tape and filled with a high-quality jointing compound to allow for minor movement.
Board feels loose after adhesive application
Check that the substrate wall is not dusty or damp. Ensure enough adhesive dabs are used and the board is firmly pressed until the adhesive sets.
Pros and Cons
Pros
- Saves significant space compared to traditional stud-wall insulation
- Provides an immediate improvement in thermal efficiency for internal walls
- Suitable for a variety of finishes including skim and paint
- Environmentally friendly composition (CFC and HCFC-free)
Cons
- Not intended for structural or load-bearing applications
- Slim profile provides less R-value than thicker insulation panels
- Requires careful handling to avoid damaging the EPS backing during installation
Setup, Compatibility & Care
Installation should be carried out by ensuring the substrate wall is dry, clean, and free of loose debris. Use high-quality drywall adhesive or appropriate mechanical fixings designed for insulated boards to secure the panels. Ensure that all joints are taped and filled to prevent thermal bridging or cracking over time.
Compatibility extends to all standard interior decorative finishes. When applying plaster skim, ensure a suitable primer is used if required by the manufacturer's specification. For care, avoid drilling deep holes through the board that could compromise the integrity of the EPS core, and always use appropriate wall anchors for any heavy fixtures such as shelving or wall-mounted TVs.
