Can I interrupt the perimeter intumescent/smoke seals with ironmongery?
If there is a smoke requirement for the door and the smoke seal is interrupted by the hinge locations, it will be necessary to run another length of the seal alongside the hinge blade to maintain continuity. The intumescent seal position has to remain as tested and should not be re-routed to another position; doing so may negate the performance of the door. In placing the intumescent seal in a different location to that tested, the seal may not react as it did during test. One possible consequence of this could be ineffectual sealing and clamping of the door leading to premature failure.
