ROCKWOOL HARDROCK® UB34
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 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.
HARDROCK UB34 has been fully tested and classified as Euroclass A2-s1,d0 (non-combustible).
