INSULATION
- Loft Rolls - 50mm 75mm 100mm 150mm 200mm. Also Available In Acoustic​
About:
Loft roll insulation is a type of thermal insulation designed specifically for insulating loft spaces (attics). It's one of the most common and cost-effective ways to improve the energy efficiency of a home in the UK and elsewhere.
​
​
Benefits:
Energy savings – Helps keep heat in during winter and out during summer.
Lower energy bills – Can significantly reduce heating costs.
Improved comfort – Reduces drafts and temperature swings.
Quick installation – DIY-friendly in many cases.
- Cavity Batts - 50mm 75mm 100mm 150mm 200mm. Also Available In Acoustic
About:
Isover Cavity Wall Slabs are high-performance glass mineral wool insulation products designed for use in external masonry cavity walls. They are manufactured by Saint-Gobain Isover and are available in two primary variants:
CWS 32: Offers a thermal conductivity (λD) of 0.032 W/m·K.
CWS 36: Offers a thermal conductivity (λD) of 0.036 W/m·K.
Both variants are available in various thicknesses to suit different insulation requirements.
​
Benefits:
Excellent Thermal Insulation
Helps keep homes warmer in winter and cooler in summer.
Leads to lower energy bills by improving the building’s energy efficiency.
Enhances fire protection for cavity walls.
Provides additional acoustic insulation, reducing external noise.

- PIR - 25mm 50mm 75mm 100mm 150mm. Bespoke Sizes Also Available
About:
PIR (Polyisocyanurate) insulation sheets are a type of rigid foam board used widely in construction for thermal insulation. Made by reacting polyol with methylene diphenyl diisocyanate (MDI) in the presence of a catalyst and blowing agents, PIR is a thermoset plastic that offers excellent thermal performance.
These boards typically come with foil facings (aluminium or composite) on both sides to enhance thermal performance and act as a vapour barrier.
​
Benefits:
Low thermal conductivity (around 0.022–0.026 W/m·K), meaning less material is needed to achieve high insulation values (U-values) Helps buildings meet stringent energy efficiency and building code requirements.
High thermal resistance with a thinner board, allowing more usable interior space or design flexibility.Ideal where space is limited (e.g., retrofits or cavity walls).
Boards are rigid, light, and easy to cut, handle, and fix into place. Reduces installation time and labour costs.
Closed-cell structure and foil facings make it resistant to water absorption. Helps prevent damp, mould, and rot in building structures.
PIR is fire resistant and will char in fire rather than melt. It typically has better fire resistance than PUR (polyurethane) foam.
PIR insulation maintains its performance over decades without sagging or degrading, ensuring long-term energy savings.
