Tenmat
In high rise buildings it is essential that passive fire protection is included in the facade build up to ensure that should a fire occur, the risk of the spread of fire is decreased. Tenmat offer a range of cavity barriers which are continuously tested to relevant industry standards by third party fire test laboratories.
All the Tenmat open state cavity barriers are tested to TGD19 and all closed state cavity barriers are tested to EN 13501-2:2016. Tenmat products allow you to meet the requirements of Approved Document B.

VFB Plus 'open state' cavity barriers are for use with ventilated cavities of up to a maximum of 450mm. These fire barriers are manufactured from a non combustible, stone mineral wool with an intumescent seal fixed on to the leading edge.
