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.

Wiltshire-based Wrightstyle used 23mm Pyrostop glass for the EI-60 test, in a very large master leaf of 1472mm wide x 2450mm high, to cover for all configurations.

This latest door system follows the introduction of a series of thermally broken fire doors earlier this year, and which are fully compatible with Wrightstyle’s SR60 curtain walling system, to provide 90 minutes of integrity and insulation (EI90).

Together, they add further options to Wrightstyle’s already extensive range of fire and smoke resistant doors, which include unlatched doors in double or single leaf format – a breakthrough fully-glazed fire door system.

All Wrightstyle’s unlatched doors are therefore 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.

“We have first-hand experience of unlatched doors with untested or incompatible fire-resistant glass are being accepted as fire doors within the regulatory definitions despite the fact that they are clearly not within the permissible limitations of their supplied test certification,” said Denis Wright, Wrightstyle’s chairman.

“Our new door system means that we now offer a complete range of fire doors, for internal and external use, and which are fully tested and compliant,” he said.
