Sheerline’s Prestige Bi-Fold doors are premium aluminium folding doors designed to flood homes with natural light and blur the boundary between indoors and outdoors with configurations from 1 to 7 panes wide.

Built with ultra-slim sightlines, high-performance Thermlock® multi-chamber thermal technology and high-performance glazing, they deliver excellent insulation and energy efficiency. The doors feature balanced aesthetics with custom single rollers, outstanding security via 5-point locking and full-length interlocks, and flexible layout options including single, French and multi-pane folding arrangements. Weather-sealed thresholds and concealed drainage ensure resilience in UK conditions, while tailored configurations and finishes allow for seamless integration into any home.
