Unlike conventional aluminium French doors, the Stellar Flush system features sashes that sit perfectly flush within the frame on both sides. This creates a seamless, flat surface that enhances the visual appeal of any elevation, whether in a contemporary home, a commercial façade, or a heritage-sensitive refurbishment.

True flush finish inside and out—no stepped profiles
Slim sightlines for increased glass area and natural light
Modern, minimalist styling ideal for new-builds and refurbishments
Compatible with side panels and fanlights for larger openings
Dual-colour options for internal/external contrast
Astragal bar options available for traditional detailing

The result is a door system that blends effortlessly into modern architectural schemes while offering the flexibility to suit more traditional aesthetics.
