A1 Non-combustible Fireproof Membranes


Breather & Vapour Control


For Buildings With a Higher Risk For Fire Safety
Suitable For Applications Over 18m High


Thermic Technology has developed The UKs First A1 Non-Combustible Reflective Membranes! Which are A1 non-combustible to BS EN13501-1 . A1 non-combustible is exactly as the name suggests, it doesn't burn, therefore it won't contribute to the spread of fire. It can also help prevent the fire from spreading from one area to another.

Suitable for use in many external wall types (timber frame, metal stud, concrete etc.) for buildings which pose a higher risk for fire safety: residential blocks of flats, student accommodations, care homes, sheltered housing, hospitals, dormitories in boarding schools with a storey above 18 m in height and high risk residential buildings (HRRB).

The Royal Institute of British Architects (RIBA) submitted evidence to the Government’s consultation on banning the use of combustible materials in the external walls of high-rise residential buildings. The RIBA recommends European Classification A1 rather than A2 in the external wall construction, to protect against production of smoke and flaming particles/droplets.
