FLATROOF LITE The Flatroof Lite insulation system offers a cost effective solution to membrane roofs. It satisfies the basic requirement for thermal, acoustic and fire performances. In Flatroof Lite roof insulation system, Roofrock 30 roofing board with the compression resistance of 30kPa is introduced as the bottom layer of the system. With the superior mechanical strength of Hardrock 60 roofing board, the insulation board is employed at the top layer to provide the stability for the overall system. Flatroof Lite is FM approved using the combination of Hardrock and Roofrock series of products.

FLATROOF PLUS ROCKWOOL Flatroof Plus insulation system provides superior mechanical strength to meetall challenges on the roof. The 60kPa roofing boards provide resistance to foot traffic during periodic roof maintenance. With ROCKWOOL state-of-the-art technology, Hardrock 60 roofing boards delivers the combination of mechanical strength, lighter weight and resistance to fire. When tested to EN 1606, Flatroof Plus can withstand a permanent load of 3kPa.

FLATROOF PRO ROCKWOOL Flatroof Pro insulation system provides an unsurpassed performance over arange of parameters. The fully tested system provides excellent acoustic performance due to the higher mass and damping ability of the boards. This roofing system is proven with excellent track records in Asia. When tested to EN 1606, Flatroof Pro can withstand a permanent load of 4kPa.
