Width of intumescent fire door strips

Guest JimGa

Recommended Posts

I have been asked by a school 'can 10mm intumescent strips be used or do they have to be 15mm'. They have not mentioned the type and function of door, however assuming that the doors are single action and 30 min or 60 min fire resisting doors what would be the minimum dimensions?

Thanks for your help,

http://www.ifsa.org.uk/pdf/Information%20Sheet%20No1.pdf it is important to check the manufacturers data sheets, there may be variations.
