Fire Safety

NVELOPE® rainscreen subframe systems are made from aluminium and stainless steel bracket and rails which are defined as Euroclass A1 Non-Combustible by EC Directive - 94/611/EC.

Made of non-combustible, sustainable aluminium and stainless steel material which offers no contribution to fire. Our NVELOPE rainscreen systems adheres to a BBA Assessment 19/5671 which describes this as:

"Behaviour in relation to fire — the systems (fixings, brackets, rails, carriers and adaptors) have an A1 reaction to fire classification in accordance with the national Building Regulations (see section 7)"

Important Points

The UK Government has announced a ban on combustible materials in external walls of residential high rise buildings
The regulation requires that all materials used in the external wall construction of a relevant building are of European Classification A2-s1, d0 or Class A1, classified in accordance with BS EN 13501-1:2007+A1:2009
Aluminium and aluminium alloys used in bracket and rail systems have a fire classification of A1 – non-combustible and offers no contribution to fire.
Regulation 7 (3) lists materials which are exempt from the limits on combustibility and the list includes 'thermal break materials' which includes our Bracket Isolator (green isolator for reference and image)
Based on EC Decision document 96/603/EC aluminium and anodised aluminium is in a list of materials to have a low level of combustibility and not require any reaction to fire testing.
