One of the most important considerations when choosing a bifolding door is the threshold level. As bifolding doors are designed to offer you a great link between the inside and the outside of the property, it is likely that you will want either a flush threshold or as low a threshold as possible.
Schuco doors come with four different threshold choices. However, the right selection of threshold can depend on several factors.
Understanding bifolding door threshold options.
How your bifolding doors are fitted and what threshold detail is achieved, primarily depends on two factors. These are whether your new bifolding doors are being installed into a new or an existing opening.
On a new opening, there is much more flexibility. Ideally your builder will work with us at The London Glazing Group whereby we can create you a desired low or flush fitting threshold. We can also provide a minimal step-over and help ensure that your inside flooring and outside paving, decking or slab is also level.
At The London Glazing Group, we are experienced at working with your builder to successfully achieve a great low threshold on a bifold door. We can achieve low thresholds at about 8-10mm while still retaining all the weathering at the bottom of the doors. Not only does this give the most natural break in how the floor levels meet, but it also tends to be the most acceptable and aesthetically pleasing solution in the home.
Where our Schuco bifolding doors are being fitted into existing openings, we can remove a course of brickwork from the bottom. These bricks are normally removed below the DPC (damp-proof course) although we strongly recommend this DPC be reinstated.
There are other solutions such as air bricks that help to circulate air and keep moisture at bay.
Schuco Bifolding door threshold choices.
With all this useful information in mind, you can now choose from four different thresholds on your new Schuco bifolding door.
Ultra Low Threshold.
The ultra low threshold is ideal for internal bifolds used as room dividers. When used externally weathering needs to be carefully considered. As this threshold is only 16mm in height overall, an Acco drain or similar water deflection arrangement needs to be in place. The DPC also needs to be present to protect your brickwork from moisture and water penetration.
Ultra Low Threshold with additional cill.
The London Glazing Group can set the Schuco Ultra Low threshold on a proprietary subcill. This provides an overall height of 42mm rather than 16mm. However, it enables the threshold to machined for water drainage. Any water that collects on the cill drains to the outside. The cill helps deflect the water away from the brickwork your door is sat upon.
Standard threshold will additional cill.
The standard threshold is the most popular and best of the thresholds available. This is 85mm in height with the cill, however as explained, setting the doors correctly can still achieve a minimal step and low threshold.
The fourth option is the standard threshold designed for an opening in Schuco folding door with the frame, draining and other features changed to reflect the different opening direction of the doors.
