Product overview: Maxdor Louvre Fire doors provide a range of louvre panels with intumescent blocks and options include 305 x 305, 457 x 457, 600 x 600 and 457 x 1500. Our fire rated louvre doors are supplied as complete units consisting of door frame, door leaf, range of thresholds, dogbolts and anti-jemmy strips. Powder coated finish and weather seals as standard and our louvre doors are available in all formats including single, double and leaf and a half.

The Fire louvre doors are tested with certain stipulations i.e. the louvre panel must have a minimum size border of door leaf surrounding, therefore the certification dictates what size louvre can go into what size door leaf. This affects the air flow. The air flow requirement of the plant room must be considered and we can happily calculate this for you and advise accordingly.
