Part M low threshold

The Composite door has a dedicated design for the low threshold specifically for the door and is Part M compliant.

The 70mm front to back and fits neatly to profile site lines. It has concealed face drainage and a thermal break.

The aluminium thresholds are designed to suit the external colour of the outerframe, white on white frame, caramel for oak frame, and brown for mahogany and cherrywood. This is not an extra cost option, it is an upgrade to the standard specification for no price difference.
