Sliding Doors

Product Description

Superior Doors' Sliding Doors: Enhancing Spatial Flexibility and Adaptability

The use of sliding doors in modern architecture and interior design continues to increase substantially. Their appeal is due to the ability to functionally open up interior spaces in a way that is difficult with most hinged options while also presenting bold design and aesthetic possibilities. 

Superior Doors pioneered the development of steel-reinforced interior doors in New Zealand, designed specifically for the unique requirements of sliding applications. All of our custom and oversized sliding doors are individually designed to work harmoniously with the desired sliding hardware system, location and environment.

Steel Reinforcement Options

Steel reinforcement is necessary for barn doors, and cavity, wardrobe and surface sliders, as well as in areas where the door may be exposed to an ambient temperature difference, a change in moisture content, or direct sunlight. A single box section is typical on the lockblock edge for hung doors, to ensure no sagging of the door over time, and two - one on the lockblock edge and one on the other - is considered typical for slider applications.
