Which board should I use to provide 60 minutes fire protection?
A board in itself has no inherent fire resistance value, only a reaction to fire classification in accordance with EN13501-1, noting that all of Promat's calcium silicate passive fire protection boards achieve the highest rating of A1 non-combustible. It's only when a board is incorporated into a tested system that the system can be given a resistan
