Bifold door thresholds
Bifold door thresholds should provide a smooth entry from outside to inside. In extreme weather conditions, it is possible that wind and sometimes rain can penetrate the low threshold. The solution is to fit the appropriate threshold in the location. If the location of the bifolding doors is exposed then you should use a rebated weather tested. With correct planning and building work, it is possible to install these rebated thresholds so that they appear flush. The difference in height between the inside and outside can be as small as 20mm or ¾ inch in old money.
Proper planning of the internal finished floor and the exterior patio finished height will allow you to pick the right frame and build the supporting brickwork so the step between inside and outside is as smooth as possible.
Our design team will work with you or your builder to help ensure the best bifolding door threshold for your project.
