Generally speaking, getting low and flush thresholds on bifolding or sliding doors is about setting your track at the right height. Then it’s about getting your internal floor up to the edge of the inside of the frame. For the outside, your decking or slabs need to meet up to the front of the frame edge. Here’s how we help you achieve it.
Flat thresholds for existing door openings
If you’ve an existing opening there will be some modification work required to this. In simple terms we remove some of the structure underneath your old doors. As a result, your new patio door sits lower and works with your existing floor internally. Externally it all depends on what you presently have. We can help you better with this once we’ve seen your existing doors in situ.
For new openings and new extensions.
When planning a new extension or building your door opening, it’s essential you involve your builder, door installer or architect if you’re using one.
It’s also highly recommended that your builder sees a physical sample of a bifolding or sliding door track. This is by far one of the best ways of understanding the relationship between your new doors to the internal and external levels. Most builders have done this before but it’s a great way of avoiding costly mistakes later.
Our Solarlux and Schuco bifolding doors come with an alternative ramp-type threshold. These differ from the conventional sunken track. At the same time, they provide accessibility for those with mobility problems and wheelchair users as well as the able-bodied.
The flush threshold for bifolding or sliding doors. Drainage considerations
Getting the ideal flush and low threshold is also essential for water drainage. As rainwater comes down your doors it needs to move effectively away and not pool on the track or threshold.
Here, we offer a range of solutions. One is for the doors to sit on a standard cill designed to move water away from the doors. Another is using a proprietary drainage system offering not only aesthetic details but excellent water drainage.
Done right, we can not only give you the flush look but also ensure your doors are dry and no water crosses the track to the inside.
