Sliding Doors

Sliding doors are popular space saving door for entry and exit doors, especially for the back yard or in smaller spaces where you don’t want or can’t have protruding doors. Sliders have also earned a reputation as the most versatile and economical door type for access to deck and patio.

FIRST™ aluminium sliding doors offer strength and security with substantial aluminium profiles, and achieve quiet, smooth sliding through the use of a high performance roller system. Also available are multi sliders which open to two-thirds of their width so they are ideal for a wide opening to the outside.

What are sliding doors?

architectural door

Doors that are mounted on sliding tracks are called sliding doors. Sliding vertically, they overlap with another door. They are usually glass, allowing the sunlight in, but saving space as they don’t swing open like a hinged door does.

When to use sliding doors

Sliding doors are especially useful for spaces where having a door swing inwards or outwards would be an inconvenience or cramp the space. Sliding aluminium doors are a good where you may want a more panoramic view, such as looking out over the garden or deck. They are quiet, with no risk of slamming in the wind. They allow the light to flood into the house, making them perfect for the darker side of the house.
