A non-combustible stone wool and fibre cement board for upstands in inverted roof finishes.
Upstand board
Ravatherm SW A2 Upstand pairs Ravago stonewool insulation slab with a 6mm fibre cement layer and is used vertically as an upstand board in the Inverted Roof finish.
It meets the current Approved Document B of the Building Regulations requirement that any attachment to the external walls of relevant buildings above 11m in height must use non-combustible materials in order to be compliant.
Our new Ravatherm SW A2 Upstand board has been tested for Reaction to Fire Classification (according to EN 13501-1) and achieves a Euroclass A2-s1, d0 classification.
