ROCKWOOL RWA45 has been developed for thermal, acoustic and fire
performance in a range of construction types. RWA45 is made up of
high-quality resin bonded slabs in a variety of thicknesses and
densities. Specialist facings are available to order to meet the
specifications of unique projects.

The ROCKWOOL slabs can be applied to an array of general building
applications for acoustic and thermal insulation of partition walls,
ceilings, floors and roofs. The multi-use solution is well suited for
easy application throughout constructions.
