One of Europe’s leading advanced glazing system suppliers has introduced an innovative leaf and half leaf fire resistant door system.
The new system complements Wrightstyle’s existing unlatched door range, which was the first unlatched advanced glazed system on the UK and international markets.
The doors, which have leafs of different sizes, provide integrity and insulation, for either 30 or 60 minutes (EI-30 and EI-60).
There can be several reasons for having a double leaf door with different leaf sizes – for example, where the opening is restricted in width, or for other ascetic, design or space restriction reasons.
The system therefore allows for easy pedestrian traffic using one operating leaf, with the other leaf coming into operation if bulkier equipment is being moved through the doorway.
One leaf (the master) is the access door that is used for pedestrian traffic, into and out of the building or offices and can either be latched or unlatched.
The other smaller leaf (the slave) is a fixed door held closed by flush bolts at the top and bottom, but which can be opened to make a wider opening for furniture and equipment to pass through.
All Wrightstyle’s unlatched doors are now available in single or double leaf format, or leaf and half leaf, and fully glazed using non-selective door leaf push/pull technology, offering a wide range of surface finishes including stainless steel.
Wrightstyle was the first company to develop a glazed unlatched door system, and has since raised concerns with government about the inadequate enforcement of fire specifications contained within the Approved Document B and the usage requirements of certification data.
