Insulation for upstands and parapet walls Consisting of a dense ROCKWOOL insulation slab bonded to a rigid 6mm exterior-grade fibre cement board, this combination of two non-combustible products provides an impact and weather-resistant insulation solution for flat roof upstands and parapet walls. The insulation of HARDROCK UB34 is manufactured from renewable volcanic stone, which produces a non-combustible roofing insulation board. The boards are compatible with a range of flat roof systems, including single-ply and inverted. Both the insulation and fibre cement board components have been tested individually and each achieved a European Reaction to Fire Classification of A1 non-combustible.
