what is the fire rating for this product, I am looking for a product with an excellent fire rating


This product has Euroclass A1 Fire Rating, Knaufs own FAQs state the below.

'Euroclass A1 means that products meet the highest possible level of non-combustibilty for thermal insulating products when classified to BS EN 13501-1, this classification is a requirement of the relevant harmonized standard as a part of CE marking. A1 means that the product has an extremely low amount of combustible material within it and therefore will not contribute to a developing fire in terms of adding fuel'
