ROCKWOOL Twinroll is stone wool insulation. The thermal insulation is non-combustible and has additional acoustic properties to absorb sound in the roof and internal spaces.

Manufactured as one 200mm roll, ROCKWOOL Twinroll is pre-cut horizontally to create the option of two 100mm rolls as one package. Twinroll is supplied on pallets and protected by waterproof covering allowing it to be stored outside. 

The insulation solution is suitable for roof spaces in all building types or can be used to overlay suspended ceilings. ROCKWOOL Twinroll does not react with any metal components in lofts, nor does it cause loss of plasticiser from PVC cabling and pipes.
