Aluminum folding door’s hardware is one of the key factor that affects the door’s operation. Most of the folding doors have 3 to 6 glass panes, so a set of good hardwares can guarantee the smooth and easy operation in any condition. Hoper’s folding door only uses top brand hardwares and it allows different opening combinations.
Our hardware uses heavy duty roller which can bear weight from 80-150kg for per panel, so for a door with thick glass, the door operation will still be smooth and light. Under the roller, there is a stainless steel track, so the roller will slide on this track instead of on the aluminum track, in this way, the low friction between roller and stainless steel track makes the roller go more smoothly. The stainless steel hinge can allow the door height up to 3000mm, and there is even hidden hinge available, so when the door is closed, the hinge will not be seen from exterior. And more and more people would like to make key alike for all of their folding doors, we can offer this option if the customer would require this. Multi-point locking system can increase the door’s security, it has 3 locking point, top, middle and bottom, while regular door only can be locked from middle.
Glass and Blinds
The standard glass configuration for the folding door is of double tempered insulated glazing of 5mm+19A+5mm which makes the glass thickness at 29mm. Double glazing can achieve good thermal and sound insulation function, and the glass performance can be much better if there is LowE and argon gas applied on it. While triple glazing is used a lot too on the folding doors, it can be of the triple pane glass with 2 layers glass spacer, for example, the glass can be like 5mm+9A+5mm+9A+5mm which makes the glass thickness at 33mm. Or the glass can be in triple pane glass with 1 layer glass spacer and 1 layer of laminated film like 5mm+0.76pvb+5mm+9A+5mm which makes the glass thickness at 24.76mm, this is called combination of laminated safety glass with insulated glass.
Built-in blinds for aluminum folding door has been a very popular optional feature on patio doors for home owners, although blinds can be controlled manually and by electricity, manual operation is still the first choice for house doors. The blinds controller can control the blinds go up and down, and it can adjust the opening degree, so you can decide how much privacy you like. This blinds normally comes with double glazing in 5mm+19A+5mm, it goes between the 2 layers of glass.
High Insulation Thermal Break
Thermal break is to use a nonconductive material that separates the interior and exterior of the aluminum to prevent the thermal energy loss, so it can keep the heat out in summer and keep the cold out in winter. Besides this high insulated barrier, there is insulation foam filled inside the frame as well which can greatly improve the energy performance as well.
So Hoper offers various options on the thermal insulation requirements to meet different climates requirements.
