VELFAC composite windows and patio doors bring together the best of both worlds; the durability and versatility of aluminium and the beauty and warmth of natural wood.
Double sliding door
Thanks to the unique construction, VELFAC double sliding doors can create an extra-wide, uninterrupted opening of up to 2.5 metres. Ideal for kitchens, dining rooms or garden rooms, each glass pane of the double sliding glass doors moves in two different directions on the track, letting more light into your home and connecting any room to the outside. VELFAC sliding exterior doors are a practical solution to open up your living space, especially when you need to save space.
One of the main benefits of a sliding double door is that it takes up very little space when open, also making it the ideal choice for narrow terraces or balconies – anywhere where space is at a premium.
The signature slim VELFAC frame design delivers a flat, seamless façade when the door is combined with other VELFAC windows, whether fixed or opening. The slim frame also improves energy efficiency meaning no cold spots, and full use of floor space right up to the glass.
VELFAC double sliding doors , also known as double leaf sliding doors, are available in two different versions:
The low threshold version is particularly useful to create an easy access for wheelchairs or prams.
