Insulated Plasterboard

A Complete Guide to Insulated Plasterboard in the UK

Insulated plasterboard is an essential solution for enhancing thermal efficiency in UK homes and buildings. By combining insulation and plasterboard into a single product, it simplifies wall insulation and helps meet building regulations for energy performance.

What is Insulated Plasterboard?

Insulated plasterboard comprises a layer of insulation bonded to the back of the plasterboard. This dual-purpose material provides both insulation and a ready-to-decorate surface, making it a popular choice for internal wall insulation and dry-lining projects.

Benefits of Insulated Plasterboard

• Improved Thermal Efficiency – Reduces heat loss and enhances the energy performance of walls.

• Space Saving – Plasterboard with insulation eliminates the need for separate insulation layers, saving interior space.

• Quick and Easy Installation – Reduces labour costs by combining two steps into one.

• Moisture Resistance – Moisture-resistant plasterboard options protect against damp.

• Soundproofing – Acoustic plasterboard options improve sound insulation.

Types of Insulated Plasterboard

• Kingspan Kooltherm K118 Insulated Plasterboard – Known for its low thermal conductivity of 0.022 and zero ozone depletion potential.

• Celotex Insulated Plasterboard – A popular option for solid wall insulation and high-performance thermal solutions.

• Thermal Plasterboards – Standard options with varying thicknesses to suit different insulation needs.

Applications of Insulated Plasterboard

• Internal Wall Insulation – Ideal for insulating brick walls and solid walls.

• Ceilings and Loft Spaces – Enhances thermal performance without adding bulk.

• Retrofit Projects – Easily applied to existing walls for energy-efficient upgrades.

How to Install Insulated Plasterboard

1. Prepare the Surface – Ensure walls are clean and dry.

2. Measure and Cut – Use a utility knife to cut the plasterboard to the required size.

3. Fix to Walls – Secure with adhesive or mechanical fixings, ensuring the vapour control layer is intact.

4. Seal Joints – Use tapered edge plasterboard for easier jointing and finishing.

5. Apply Finishes – Once installed, decorate as you would with normal plasterboard.

Choosing the Right Insulated Plasterboard

• Thickness – Options range from 9.5mm to 12.5mm plasterboard with varying insulation thickness.

• Performance – Choose products with fire-resistant or moisture-resistant properties for specific applications.

• Brand – Kingspan Kooltherm K118, Celotex insulated plasterboard, and other leading brands offer reliable solutions.

Conclusion

Insulated plasterboard is a versatile and efficient way to insulate walls while simplifying the installation process. It provides thermal performance and reduces energy bills, making it an essential product for UK homeowners and builders.
