After the catastrophic fire in 2017 in London's Grenfell Tower there has been an ever-increasing demand for "smoke-tight" lift doors. On the one hand, such door systems cannot be realised due to design factors and on the other hand there are standards- related factors that also impede this. 

To prevent smoke  spreading through the lift doors, through the lift shaft and into other floors, there is only one possibility: The landing doors must be combined with a smoke-tight seal that does not impair the fire-certification criteria.

MEILLER has developed the solution with SmokeGuard®: Landing doors, fire-tested per EN 81-58, are combined with a smoke protection curtain from a renowned manufacturer. 

An accredited fire institute has tested this com- bination and confirmed that the installation of the smoke protection curtain on the fire-tested landing door in no way affects the fire resistance.

In practice, a number of prerequisites must be observed when ordering the landing doors: EvoN installation type (niche installation), frame width 100 mm etc. The frame and sill are then pre- pared by MEILLER for the installation of the smoke protection curtain. The curtain itself is installed at the construction site on the frame and sill of the landing door.

Thanks to a universally applicable control system for the smoke protection curtain (static or dynamic fire control, fire alarm control panel or others), the triggering of the smoke protection curtain can be integrated into any conceivable scenario. This must be implemented accordingly by the lift manufacturer or the controller manufacturer.
