How Does the Door Bottom Guillotine Work?

This system completely seals the gap on the floor by pressing the gasket downwards from its internal mechanism when the door closes. This effectively prevents both air leaks and smoke infiltration. In the event of a fire, it enhances safety by preventing smoke from spreading to other areas. Additionally, it reduces heat loss, provides sound insulation, and offers protection against pests.

The door bottom gasket forms an airtight barrier when compressed against the threshold profile. This structure not only improves energy efficiency but also requires minimal maintenance throughout its lifespan.
