Roof Insulation Suppliers in Cardiff
Welcome to Roofbase Cardiff – Your Leading Supplier for High-Performance Thermal Solutions
At Roofbase Cardiff, we understand that effective insulation is the backbone of any successful roofing project in South Wales. Whether you are working on a residential renovation in Roath, a commercial development in Cardiff Bay, or a new build in Pontcanna, our branch provides the high-quality materials required to meet modern thermal standards and reduce energy costs.
Our Specialist Insulation Range
Proper insulation is essential for protecting properties against the unpredictable Welsh weather. From the coastal winds of the Severn Estuary to the damp winters of the Valleys, high-performance insulation ensures year-round comfort.
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.
