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.
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:
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.
