Our Specialist Insulation Range
Every project has unique requirements. If your job demands specialized barriers, multi-foil insulation, or tapered roof schemes to manage water runoff on flat roofs, Roofbase Plymouth has you covered. Our staff can help you calculate the exact "U-values" required for your project, ensuring your build meets or exceeds local authority standards.
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.
