|
What are the Advantages/Disadvantages of each Threshold Option? |
| |
Top Running - The bulk of the gearing is at the Top of the door.
Ad: The threshold/up-stand at the base of the door is slightly smaller, compared to a Bottom running door.
Dis: The door must be securely fixed to either a lintel/RSJ or a solid fixing, otherwise the doors will drop making them unusable. |
| |
|
| |
Bottom Running - The bulk of the gearing is at the Bottom of the door.
Ad: As the bulk of the weight is at the base of the door, the chances of the door dropping are slim.
Dis: The threshold/up-stand at the base of the door is slightly bigger compared to a Top running door. |
| |
|
| |
Low Aluminum Threshold - The bulk of the gearing is at the bottom of the door
Ad: The threshold/up-stand at the base of the door is flush against the floor.
Dis: The doors can only Open Inwards. Internal doors can open either In/Out. |

What opening styles are available? |

| |
|
|
Are the doors internally or externally glazed? |
| |
Internally, this increases security as there is no access to the beads from outside the property. |
| |
|
|
Can the doors open in or out?* |
| |
The UPVC Bi-folding doors can be manufactured both inward and outward opening. However, it is recommended that outward opening doors must only be fitted internally, i.e. between the living room and conservatory. Outward opening doors are NOT recommended for external use, as the hardware can be exposed to all weather conditions. The hardware manufacturers will therefore not guarantee parts, on external outward opening doors.
If you wish to order an outward opening door, and fit it externally, please be aware of the above omission on the guarantee. |
| |
|
|
Ideally how wide should each individual panel be? |
| |
There is a weight limit on each panel of 80kg, we recommend you do not exceed 900mm per panel, and the minimum door width to be no smaller than 450mm. The maximum door height is 2400mm high. |
