Manufactured from renewable volcanic stone, HARDROCK® (DD) TRB is rated Euroclass A1 non-combustible, boasting excellent fire performance qualities. The stone wool insulation board is manufactured using ROCKWOOL-patented dual density technology which results in the top layer of the board being a higher density.
HARDROCK® (DD) TRB has been specially optimised for the insulation of un-trafficked thermal flat roof applications and is suitable for use with mechanically fixed single-ply membranes. The insulation is robust and able to bear normal foot traffic during installation, along with routine maintenance inspections - making it ideal for use on distribution centres and warehouses.
In addition to having a low lambda value, ROCKWOOL HARDROCK® (DD) TRB achieves U-values as low as 0.15 W/m2K in a single layer. The boards are easy to handle onsite, speeding up the installation process and reducing labour costs.
