General Purpose Insulation Boards

PIR Insulation Boards

Our selection of PIR (Polyisocyanurate) insulation boards, such as Celotex GA4000, offers high thermal efficiency and strength. Ideal for floors, walls, and roofs, these boards are versatile for both new build and refurbishment projects.

Thermal Bridging Boards

Products like Celotex TB4000 are designed to address thermal bridging, enhancing overall energy efficiency. These boards are an excellent choice for continuous insulation across junctions.

Specialised Insulation Boards

Insulated Plasterboard

Options like Celotex PL4000 and Kingspan Kooltherm K118 combine insulation and plasterboard for a two-in-one solution, perfect for internal walls and loft conversions.

Rainscreen Insulation Boards

Products such as Kingspan Kooltherm K15 are specifically designed for rainscreen cladding applications, providing thermal performance and moisture management.

High-Performance Insulation Boards

High-Density Boards

For areas requiring extra strength and rigidity, our high-density options like Kingspan Thermawall TW55 are ideal, especially for steel or timber-framed constructions.

Extra Thick Insulation Boards

Products like Celotex XR4000, available in larger thicknesses, are perfect for projects needing higher insulation levels without compromising on space.

Alternative Insulation Solutions

Foil Insulation Rolls

Our Superfoil range, including SFBA MP and SF40, offers a flexible, easy-to-install solution, suitable for a variety of applications, including under floors and in walls.

Rockwool Insulation

Rockwool options provide excellent sound insulation and fire resistance, ideal for party walls and other areas where acoustic performance is crucial.

XPS and EPS Boards

Warmline XPS and EPS insulated plasterboards offer a balance of insulation and weight, suitable for areas where load is a concern.

Considerations for Selection

When selecting wall insulation, consider factors like thermal performance (U-values), fire resistance, acoustic properties, and environmental impact. The choice will depend on your specific application, be it residential, commercial, or industrial.

Remember, proper installation is key to maximising the benefits of insulation. Consult with professionals to ensure the best fit for your project.
