In any building, fire safety is of paramount importance. It’s crucial that architects, specifiers, and installers know how the insulation they put into a building will react in the event of a fire. And is even more important for occupants to have confidence in the materials used in their homes. Superglass glass mineral wool insulation offers thermal insulation with the reassurance of accredited fire credentials – and it’s been thoroughly tested to prove its reaction to fire. All Superglass Insulation products are deemed non-combustible with a fire classification of Euroclass A1 when tested to British Standard BS EN 13501-1:2018 Reaction to Fire.
What does non-combustible mean?
‘Non-combustible’ refers to a material that does not ignite, burn, or support combustion when exposed to fire or heat. In other words, non-combustible materials do not contribute to the spread of flames. This property is crucial for building materials, as it enhances fire safety and helps protect structures and occupants in the event of a fire.
Reaction to Fire
This is a measurement of how building materials or systems will contribute to the development and spread of a fire, especially in the early stages, when evacuation is crucial.
All Superglass insulation materials are given a Euroclass reaction to fire classification in accordance with BS EN 13501:1:2018 Reaction to Fire.
Testing assesses the performance of materials in terms of fire behaviour, smoke production, and flaming droplets, resulting in a range of classification possibilities.
Products which have a fire classification of Euroclass A1 do not produce smoke or droplets.
Typical Insulation Product Euroclass Reaction To Fire Classifications
The graph below shows a range of insulation products relevant to their ability to withstand fire. It’s clear to see that Glass Mineral Wool , as a non-combustible product, provides protection for a building and its occupants in the event of a fire breaking out.
All Superglass products are non-combustible and achieve the highest possible Euroclass A1 Reaction to Fire classification.
By choosing non-combustible insulation materials, building designers and specifiers can help mitigate the risk of fire within the building fabric from the outset.
*As set out in changes to the building regulations 2010 which bans the use of combustible materials, limiting the use of materials to those that achieve Al or A2-s1,do on buildings in scope of the ban [as defined in regulation 7(4)]
Notes: Other classifications of smoke and flaming droplets within A2 are classed as limited combustibility. (Not shown here as no insulant falls in that category)
NPD – No Performance Determined. In this instance no performance is declared and information regarding reaction to fire performance is unknown. Illustration for guidance only.
It is crucial to check the actual Euroclass reaction to fire classification of a product before use. Alway refer to the product manufacturers literature.
Tested for total reassurance
Superglass insulation has undergone the strictest independent testing to BS EN 13501-1:2018 Reaction to Fire standards. This follows the industry-standard Euroclass system, which classifies the reaction to fire of a building material with ratings of A1, A2, B, C, D, E and F. A1 and A2 ratings mean a material does not burn or contribute to the spread of flames or emit any significant levels of toxic smoke in a fire, while materials rated B to F are combustible.
According to British Standard BS EN 13501-1: Fire classification of construction products and building elements, “Euroclass A1 products will not contribute to any stage of the fire including the fully developed fire.”
