Folding Door with flexible construction
Folding doors are robust and all-round industrial doors that requires little space, have few moving parts and lower service needs than other door types. We tailor your folding door with regards to size, number of panels, windows, fittings and appearance.
Did you know that folding doors generally have lower usage costs than other door types?
Size & panel division
Width: from 1.3 meters up to about 20 meters.
Height: The maximum height is 6 meters.
We build up your folding door with the number of sections required to fit the width of your doorway. A manual door can have between 1 – 20 sections and an electrically operated 2 – 4 panels. Normally, the same number of panels are folded in each direction, but a folding door can also be built so that folding/opening is asymmetrical or only in one direction.
Examples of different panel divisions for a folding door:

The density of the filler foam provides a very good insulation, which in gives you a low usage cost and a warm indoor environment.
U-value: best cut approximately 0.22 W/m² °c.
U-value of an example door 5×5 meter: 0.90 W/m² ° C.
T-value Example door: 1 m³/h & m²
Metal sheet: 0.6 mm SSAB greencoat

Seals & Fittings
Specially designed sealing
The folding door seals are specially designed and developed to provide maximum sealing. Thanks well dimensioned, special seals between panels and in all corners, the folding door closes precisely and seals effectively, the folding door has a T-value that exceeds the highest prescribed European requirements with three times.
Torverk folding door is dense even in the hurricane!
As standard we deliver the manual doors with padlock able surface-mounted espagnolett, which is openable from the inside. Q-Door door can also be equipped with cylinder lockable espagnolett, which is built into the door blade. With a cylinder lockable espagnolett, it’s possible handles on both the inside and outside.
Electrically operated doors do not require an additional lock because they are designed so they can’t be opened from outside without an open impulse or disconnecting. You can get an electrically operated folding door with optional espagnolett or cylinder locking.
If you choose a Q-Door folding door with a pass door, you have the option to choose between different types of locking.
Our own fittings
Torverk fittings are robust and have low friction, which gives an easy handling when opening and closing of the door. The fittings also affects your folding door life span. Therefore, Torverk’s folding doors are equipped with robust fittings, which we manufacture ourselves.
Our frame hinges withstands high mechanical stress and are available in two variants:
- Standard Hinges – The door panel is supported by a steel ball resting on a brass pin
- 3d Hinge – The hinge lifts the door 15 mm at the opening
Torverk offer different types of drive units to our folding doors. Type of drive unit depends on the size of the door and the existing spaces around the doorway.
TOP-MOUNTED MOTOR to 3-and 4-panel doors. The operation is limited to maximum height = 5 meters, and a maximum of 25 m² door area for 4-panel door, or 19 m² for 3-panel door.
SIDE-MOUNTED MOTOR for 2-, 3-and 4-panel folding door. Used where there is no space above the door or if the doorway is greater than 5 meters. Side mounted drive units are suitable even when the area exceeds the maximum limit for top-mounted drive units.
LINK DRIVE to 2-, 3-and 4-panel folding doors. Used when there is little side space and large opening area. Height max = 5 meters.
Windows & Pass Door
As standard window we use energy glass where the window frame of aluminum has broken thermal bridge. This means that we ensure that the door’s windows have as low impact on the total U-value as possible. We have a wide range of standard sizes, but if you want a different size we can solve that.
It is worth considering that in the standard version a door panel should not be fitted with a larger glass surface than about 30 % in manually operated door and approximately 45 % in electrically operated door.
If you are also going to use the folding door for personnel passage, we can produce a door panel with a pass door. Opening the entire gate for personnel passage is both impractical and incorrect from an operational and energy point of view.
Pedestrian doors have a standard height of 2050 mm and can be fitted with different types of locking, door closers, safety systems and windows.
