Grenfell changed how we all view Fire Safety
Insulation materials and construction membranes have varying levels of combustibility. Highly combustible materials can contribute to fire development and spread, particularly in the early stages of a fire when evacuation is crucial.
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.
Typical Euroclass Reaction to Fire Classifications:
|Non combustible||Limited combustibility||Very limited combustibility||Limited combustibility||Medium contribution to fire||High contribution to fire||Easily flammable|
|TLX Silver||TLX Gold
|Unfaced Glass Mineralwool
Unfaced Rock Mineralwool
|Polystyrene XPS & EPS|
Started post Grenfell with our timber frame customers asking us for non-combustible wall membranes and multi foil insulation. They were surprised that there weren’t any non-combustible breathable wall membranes available.
Many of our customers believed that "Class 1 surface spread of flame" reflective wall membranes that they were using were non-combustible but had not realised they were also Euroclass E and that they ignite within 15 seconds and have a ‘high contribution to fire’ (see table above). These "Class 1 " ratings only relates to the aluminium surface not the easily flammable textile backing.
Our A1 range of products gives added fire safety during construction and maintenance, when buildings are exposed to accidental fire or the posibility of arson.We now have a range of:
