Bi fold Doors & Multi-fold Doors
This design surely has to be one of the most impressive patio doors; the folding door action really opens up your home; they bringing space and light that other doors just cannot match. The impressive clear opening space is achieved by stacking or folding the doors fully to the left or right – you can also choose to stack the doors or leaves to the outside or inside of the room. This gives almost an extra 50% of clear opening when compared to the “standard” patio door.
Although the door leaves (panels) may look heavy and cumbersome, the smooth glide tracks allow the opening and closing of the doors with almost no effort. Features Include:
- Internal beading
- Toughened or laminate glass
- Stainless steel tracks & top guides
- Multi-point locks & shoots bolts (bump, snap & pick resistant)
- Draught proof weather seals
- Argon filled, sealed double glazed units
- Energy Efficiency
Because of having such a large amount of glass separating you from the weather, consideration of the thermal efficiency of the sealed glass units for bi fold doors should be high on the list.
Low-e glass with the sealed units filed with an insulating gas, such as Argon can be used in order to increase the performance of the doors. Installations should meet regulations for thermal efficiency and have a rating label from the BFRC. (Find out more on rating here)
