Thresholds (the part of the door you step over as you enter your home)
Full frame threshold
This is the more traditional threshold where the outer frame runs along the bottom of the door. This means your door will shut into the rebate of the frame on the bottom, as opposed to a low threshold, which uses rubber gaskets for compression.
Low frame threshold
This is similar to a full frame threshold, however the outer frame on the bottom of the door is reduced in height, which means there is less of a trip hazard as you step into the property.
This option is specifically designed for ease of access and wheelchair access. The wheelchair threshold is part M compliant, and is aluminium as opposed to plastic. The threshold will be powder coated to match the colour of your outer frame.
When choosing your threshold, consider the threshold on your existing door. If you are going for a low threshold option, check the internal floor level to ensure there will be enough clearance from the underside of the door/sill to the bottom of the door leaf. Here is a quick size guide:
Threshold height reference guide:
Full frame threshold height – 53mm internal 72mm external
Low frame threshold height – 12mm internal 32mm external
Wheelchair threshold height – 15mm
This is the most common type of sill and will leave a 80mm overhand at the bottom of the door. This is to drain rain water away.
This sill has less of a projection and leaves a 15mm overhang – these are less common, however our surveyor will advise the best sill for your home.
85mm & 150mm sill height - 30mm
