EXTERNAL ENVELOPE 35 Ahead of the curve
As an alternative to revolving doors, automatic curved sliding doors are a great way of combining efficiency with a stunning focal point at a building’s entrance. James White from Record UK explains the options for specifiers
C
urved sliding door systems offer a variety of options. These range from complete circular doors containing a pair of external and internal doors supported by a glazed drum creating an entrance vestibule, to single door suites that follow the curve of a facade to maintain an uninterrupted aesthetic. They offer the benefit of maximising throughput capacity with relatively unimpeded access to all building users.
Circular sliding doors create visually stunning entrances which provide the maximum clear opening in any given footprint, making them ideal in high pedestrian foot traffic environments, particularly at peak times in commercial offices, luxury shops, shopping centres, hospitals, hotels and leisure facilities. Circular sliding door systems are inclusive, as they provide clear unrestricted and unobstructed access to all building users without the need for an additional pass door. When linked to a fire alarm system, they are also suitable for the final exit point for all. As standard, the operators used also contain an integrated battery backup unit to ensure emergency operation in the event of a power failure, for compliance and peace of mind. When compared to a linear sliding door
system, for example, circular sliding doors offer improved aerodynamic properties as they deflect and dissipate wind pressure much more effectively while reducing the ingress of cold air. The addition of a concealed warm air curtain further improves this.
Flexibility in design
There are many options available to architects when it comes to curved and circular sliding doors, including concave and convex designs. This gives designers greater freedom to create individuality and a sense of intrigue at entrances using varying degrees of curvature or radius, to complement the architecture of the building.

There are various finish options too. From simple RAL specification polyester powder- coated finishes to bespoke metal finishes such as polished stainless steel and bespoke cladding. Most requirements can be accommodated, and the earlier specification teams are involved in the design process the better.
Drive options
An in-ground drive is the best option when the light transmission is a priority, because there is no need for a solid metal canopy
