Energy-Efficient, Waterproof & Long-Lasting Roofing Solutions
Warm-roof insulation and seamless liquid roofing systems — cold-applied, joint-free and backed by 10–25 year warranties.
Why it matters
Flat and low-pitched commercial roofs fail at the joints and suffer condensation. Warm-roof insulation plus a seamless liquid membrane removes both weaknesses in one specification.
Why choose us
Certified trained applicators, UK & EU building-regulation compliance, 10–25 year warranties and site-specific technical support.
External roof insulation
Warm-roof insulation above the structural deck for flat and low-pitched commercial roofs — energy efficient, reduces condensation, compatible with liquid membranes, retrofit and new build.
Liquid roofing & polyurea coatings
Seamless, flexible, fully bonded, cold-applied systems (PU, PMMA, bitumen emulsions, polyurea) with no hot works. Polyurea coatings are rain-safe in seconds and bond to concrete, metal, timber and existing membranes.
