Thresholds

Bifold door thresholds

Bifold door thresholds the best threshold is one which provides a smooth entry from outside to inside.  The only problem is that all of the low thresholds available on the market are designed for internal use or sheltered locations.  This means that 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 threshold.  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.

Our design team will work with you or your builder to help ensure the best bifolding door threshold for your project.

After you have placed your order we will email a set of threshold options and building details for you.  You will also receive a copy of the available door opening options to ensure you pick the correct design of door.

	Smart systems 20mm low bifolding door threshold show here with ramps.  This threshold is ideally used in sheltered locations or for internal doors.
Smart systems bifolding door 15mm threshold used in sheltered locations or for internal doors.  This drawing includes the ramps for easy access.
	Smart systems bifolding door 50mm rebated weather tested threshold can be used in any external location.  Note the proposed finish floor level as indicated on the drawing.  This and any of the above threshold can be installed onto a 150mm cill as shown in the drawing.  We are finding many of our clients today require the flush feel between inside and outside and are installing this threshold bringing the decking or outside tiling to close under the door when opened.
