Available in a selection of construction designs from single skin to insulated fire rated wall systems. The blast relief panels allow the internal building overpressure to be relieved and the accidental blast vented to the external atmosphere, thus minimising the requirements for blast resistance of the building structure. The blast relief panels are designed to relief at between 5 and 10 kPa internal pressures. For larger relief areas, a modular format is provided with the panels assembled to a grid system for vertical or horizontal blast relief.
Where required blast relief doorsets can be manufactured incorporating blast relief panels within the doorset.
