A threshold is the bottom section of the frame on a door. A standard threshold means that the bottom section of the frame will match the rest of the outer frame. This will usually create a raised step; therefore, you should speak with your installer to establish how the door will be installed. It should be noted on the point of order if you require easy access for perhaps a wheelchair user or small children, as this will likely affect your choice of threshold. In order to comply with Part M of the building regulations, on most new builds, you will need to specify a low Part M compliant aluminium threshold.
