Sisalation
Reflective Insulation
Sisalation is a reinforced reflective foil insulation range for commercial and industrial roofing systems. Its reflective aluminium foil surfaces help reduce radiant heat transfer, while the reinforced membrane provides strength beneath metal and tiled roofs.
Sisalation FR405 is designed for light industrial and commercial buildings. FR430 provides a heavier construction for factories, warehouses and demanding industrial roofs. Fireshield NC502 provides the highest fire performance in the range for projects with stricter fire requirements. Every roll measures 1.25m × 40m, providing 50m² of total coverage and approximately 44m² of effective coverage after overlaps. Compare the options to choose suitable roof insulation for your project.
