Our Specialist Insulation Range

Finding the right balance between thermal performance and budget is key.

We supply the most reliable materials currently used in the UK construction industry.

PIR Insulation Boards

Polyisocyanurate (PIR) is one of the most efficient insulation materials available. These rigid foam boards offer high thermal resistance with minimal thickness, making them perfect for projects where space is at a premium.

  • Best for: Pitched roofs, floors, and framed walls.

  • Key Benefit: Features a low-emissivity foil facing that reflects heat back into the building.

Fibreglass Roof Insulation

A classic and cost-effective choice, fibreglass roof insulation (mineral wool) is known for its excellent thermal and acoustic properties. It is lightweight, easy to install between joists, and provides an effective barrier against heat loss in large loft spaces.

  • Best for: Cold roof lofts and timber frame structures.

  • Key Benefit: Naturally fire-resistant and highly breathable.

Multifoil Insulation

For those looking to maximise space without compromising on R-values, multifoil insulation is the modern solution. Comprised of multiple layers of reflective foil and wadding, it manages all three types of heat transfer: radiation, conduction, and convection.

  • Best for: Renovations, barn conversions, and tight rafter spaces.

  • Key Benefit: Extremely thin profile that acts as both insulation and a vapour control layer.

Flat Roofing Insulation

Insulating a flat roof requires specific materials that can withstand compression and provide a stable base for waterproofing membranes. We supply dedicated flat roofing insulation solutions, including tissue-faced PIR boards designed for compatibility with torch-on felt or single-ply systems.

  • Best for: Extensions, garages, and commercial flat roofs.

  • Key Benefit: High compressive strength to support maintenance foot traffic.
