Rockwool, the world's leading manufacturer of non-combustible stone wool insulation, is launching Hi-Impact soffit slab - a thermal and fire-rated solution for concrete roof soffits.
The new product, created in partnership with Promat, a market leader in passive fire protection, has been developed in response to demand from Rockwool's customers.
It means Rockwool now has a complete solution providing outstanding thermal and fire protection of car parks, both for new builds and refurbishments.
Rockwool's Hi-Impact soffit slab is non-combustible and has an A1 classification for reaction to fire. It has been independently tested to BS476-4 and EN 13501-1 standards by Exova Warringtonfire, and offers up-to 4 hours fire protection to a concrete soffit. This test makes Hi-Impact Soffit Slab the only solution for concrete soffits that has been fire tested in conditions that match its application.
Andrew Champ, Marketing Director from Rockwool, said: "In response to demand from our customers we decided to team up with Promat and develop this soffit slab, which marries exceptional thermal and fire protection with the flexibility of use people have come to expect from Rockwool products. We think the Hi-Impact soffit slab is the best product of its kind on the market for protecting concrete soffits, particularly in car parks."
The soffit slab also offers the thermal properties of Rockwool stone-wool insulation, combined with the impact resistant Promat PROMATECT HD board. The Promat facing board is able to be decorated on-site to match colour schemes.
When fitted to a 150mm concrete soffit, 136mm thick Hi-Impact soffit slab allows specifiers to meet Part L regulations of 0.25 wK/m2. The more stringent requirement of 0.20 wK/m2 can also be achieved using 166mm of Hi-Impact soffit slab.
The Hi-Impact soffit slab has been developed to ensure cost effectiveness and ease of installation and can be easily cut to accommodate services. The Rockwool core of the slab allows for an easier fit into the uneven surfaces of soffits; maintaining the aesthetic line and level of the ceiling without creating air gaps which may affect thermal performance.
Soffit slab is also available as un-faced, with black or white tissue facing or aluminium foil facing.
