22.5mm Tekwarm HP+ Insulated Plasterboard

Tekwarm HP+ 22.5mm insulated plasterboard combines high-performance grey expanded polystyrene (EPS) insulation with 12.5mm tapered-edge plasterboard, providing a convenient solution for improving the thermal efficiency of internal walls. Designed for refurbishment and new-build projects, this insulation board helps reduce heat loss while combining insulation and drylining in one product.

The 22.5mm overall thickness includes the insulation layer and 12.5mm plasterboard facing, making it suitable for projects where space is limited and improved wall insulation is required.

Key Benefits of Tekwarm HP+ Insulated Plasterboard

1. 22.5mm overall thickness: Combines insulation and 12.5mm plasterboard for a space-efficient wall lining solution.
2. Improved thermal performance: Grey HP+ EPS insulation has a thermal conductivity of 0.030 W/mK, helping reduce heat transfer through walls.
3. Carbon-enhanced insulation: The grey colour comes from a carbon additive that helps disperse and reflect heat radiation, improving thermal performance compared with standard white EPS.
4. Flexible installation: Designed for compatible adhesive or mechanical fixing methods, subject to the manufacturer's installation guidance and the substrate.
5. Efficient drylining: Integrates insulation and plasterboard into one board, helping simplify installation and reduce separate fitting stages.
6. Environmental performance: The product information states zero ozone depletion potential (ODP) and a global warming potential (GWP) below 5. Refer to the manufacturer's current datasheet for confirmation.

Applications of 22.5mm Insulated Plasterboard

Tekwarm HP+ insulated plasterboard can be used in suitable internal wall-lining systems where additional thermal insulation is required. It may be considered for refurbishment projects, renovations and new-build interiors, including situations where maintaining internal room space is important.

For stud wall applications, additional insulation may be installed between the studs where specified by the overall wall design. Always ensure the complete construction meets the required thermal, moisture and acoustic performance standards.

Installation and Handling

Install Tekwarm HP+ insulated plasterboard in accordance with the manufacturer's instructions and the requirements of the selected wall system. Check that the substrate, fixing method and joint treatment are suitable before installation.

This product is not intended for damp or continuously humid conditions. Consult the technical datasheet for full installation, storage, handling and safety guidance.

Why Choose Insulated Plasterboard?

Insulated plasterboard combines a thermal insulation layer and plasterboard facing in a single product. Compared with installing insulation and plasterboard separately, this can simplify drylining work and help save installation time.

When correctly specified and installed, insulated plasterboard can help reduce heat loss, improve indoor comfort and support a building's overall energy efficiency. Actual results depend on the existing wall, insulation thickness, installation quality and the performance of the complete building fabric.

Product specification: Tekwarm HP+ grey EPS insulated plasterboard, 22.5mm overall thickness, including 12.5mm tapered-edge plasterboard. Thermal conductivity of insulation: 0.030 W/mK.
