This aluminium threshold sill is designed for installation at the base of external doors, providing a functional barrier to bridge the gap between interior flooring and outdoor surfaces. It helps to reduce draughts and limits the entry of water or debris beneath the door.
Typically fitted on standard-sized external doors in residential or light commercial settings, the 1830mm length allows for installation in one piece, minimising the need for joints. It is often used during renovations and new builds to support energy efficiency and maintain a clean threshold area.
1830mm length covers most standard door widths in a single section
Lightweight aluminium construction resists corrosion and handles frequent use
Low-profile shape improves accessibility and reduces trip risk at entry points
Suitable for a wide range of external door installations
