Slim sliding glass doors with 20mm sightlines
The Sieger Slim Sliding Door is a minimal aluminium sliding glass door system designed for properties where large views, natural light and indoor-outdoor living are central to the project. With vertical sightlines of just 20mm and the ability to hide the outer frame within the surrounding wall finishes, the system creates a refined glass-led appearance without losing the performance needed for modern homes.
Suitable for extensions, new-build homes, balconies, renovations and roof terraces, the Sieger Slim Sliding Door combines slim aluminium profiles with weather-tested performance, integrated locking and a flush threshold detail designed for UK conditions.
Sieger Systems supplies and installs slim sliding glass doors across London, Buckinghamshire, Berkshire, Oxfordshire, Hertfordshire, Surrey, Bath, Bristol and Somerset.
