What are the Differences between our sliding glass door systems?

We all love the thought of opening the entire rear wall of our home to the garden but let’s be honest; in the UK the amount of the year in which we can actually do this is limited to a month or so in summer.

Modern slim frame sliding glass doors, are becoming a much more popular option for architects and design-minded homeowners looking to create a modern, indoor-outdoor rear patio design.

Slim Frame Sliding Glass Doors from Minimal Windows

The slim framing associated to sliding patio doors, even when closed, means that the boundaries between inside and outside are blurred. If you opt for a sliding door system that offers a full floor to ceiling glass finish, like minimal windows, then that barrier is merged even further.

The 21mm aluminium frame and the flush tracks create impressive floor-to-ceiling glass facades of smooth sliding glass suitable for use on extensions, renovations and contemporary new builds with a modern, minimal design aesthetic.

Minimal windows are the perfect sliding door system for projects wanting to minimise the barrier between inside and out and are the slimmest framed option available.

Aluminium framed sliding doors are at the forefront of contemporary architectural design. Sieger Systems can design and fabricate the framing as little as 30mm, offering a clean contemporary finish creating large elevations of aluminium framed sliding glass.

Multiple configurations are available all using modern and innovative fabrication techniques to achieve the best sliding doors.

Ultra-slim sliding glass doors are the perfect solution if slim sightlines are desired but the budget is tight. This system is more cost-effective than minimal windows but maintains a modern finish and high performance.
