Single sliding door

Single sliding door

Rather than folding back on themselves like bifold doors, or opening on hinges like French doors, in a single sliding door one glass panel slides horizontally along the track, taking very little room to operate. This makes single sliding doors ideal for balconies and smaller gardens, or for rooms where there is not much floor space.

Our sliding doors are easy to operate and are available in two different versions:

• Standard threshold: 70mm
• Low threshold: 24mm

The low threshold sliding door has a major benefit to those that need to move inside and out their home using a wheelchair, a buggy or pram, making the access to your house even easier.

Both styles feature the same beautiful slim profile, high security , excellent energy performance and are Part Q compliant, and can be manufactured to create up to 1.2 metres free opening.

One of the biggest benefits of installing a sliding glass door is they take very little space to operate. Where hinged doors require space to swing open, sliding doors operate sideways. This makes them ideal for use where floor space is a concern both on the inside or the outside of your house.

Sliding doors offer more controlled ventilation than bifolding doors because allow you to open the doors partially to ventilate each room without making your whole house cold.

VELFAC sliding doors are also very easy to operate even with only one hand, despite the size or weight of the door.

The most affordable option is UPVC, but this material it’s not particularly strong, so the frame of the sliding door will be fairly thick, blocking your view. Timber is a classic choice because it's a very warm material, but requires painting and maintenance . Aluminium offers high durability and the possibility to have a virtually uninterrupted views, but it is not as thermal efficient as wood. The best option would be a composite sliding door which combines wood and aluminum together, insuring slim frame, high thermal efficiency, and durability of minimum 40 years.

All VELFAC sliding doors are made to measure, therefore you can be sure that the door will fit exactly your home. The single leaf sliding door can be manufactured to create up to 1.2 metres free opening.
