Glass-to-glass cornerless windows are designed without a traditional corner post, allowing two panes of glass to meet cleanly at a corner. This creates an uninterrupted glazed corner that maximises natural light and enhances the visual connection between inside and outside spaces.

Are glass-to-glass cornerless windows suitable for uPVC?

Yes. When correctly designed and manufactured, glass-to-glass cornerless windows can be produced in uPVC. Fenster manufactures these systems using REHAU profiles, ensuring the window delivers the required performance while achieving a clean, contemporary appearance.

Where are Fenster’s glass-to-glass, cornerless windows manufactured?

All glass-to-glass cornerless windows from Fenster are manufactured at our factory in Bury, Greater Manchester. Producing them in-house allows us to maintain quality control and support trade customers with practical guidance throughout the process.

What colours and finishes are available?

Fenster glass-to-glass cornerless windows are available in the full range of REHAU colour options. This includes modern finishes such as smooth Midnight Black for a contemporary, aluminium-style look, as well as traditional timber-effect foils, such as Turner Oak. This flexibility allows the windows to suit both modern and more traditional properties.

Are glass-to-glass cornerless windows suitable for extensions and new builds?

Yes. These windows are commonly specified for rear extensions, open-plan living areas, garden rooms, and contemporary new builds. Suitability depends on the overall design and structural considerations, so early discussion is recommended.

Do glass-to-glass cornerless windows require special structural support?

In most cases, yes. While the corner itself is glazed, the surrounding structure must be designed to support the opening safely. Fenster works with installers and specifiers to discuss feasibility and ensure the window design aligns with the project requirements.

Are these windows available directly to homeowners?

Fenster supplies glass-to-glass cornerless windows to the trade. Homeowners should speak to their builder or installer, who can then contact Fenster to discuss specification, options, and suitability for the project. Fenster can recommend an installer if you don't have one.

A broken window or door can be stressful, but acting quickly can help ensure your safety and minimize further damage. First, secure the area to prevent injuries, document the damage for insurance purposes, and check whether your home insurer covers repairs. If needed, arrange for a professional repair or replacement.

Yes. The Mahogany foil finish is being discontinued from the REHAU range. Existing windows remain fully supported, but exact colour matching may not be possible in the future.  Trade Window & Door Insights | Installer Blog | Fenster Trade Frames 

Spraying uPVC frames is not recommended as a like-for-like replacement. Sprayed finishes do not match factory-applied foils for durability, colour depth or long-term consistency.   Trade Window & Door Insights | Installer Blog | Fenster Trade Frames 

Homeowners can either replace now to maintain consistency, or consider a phased upgrade using an alternative colour for part of the property, such as the front elevation. 

Yes. Modern REHAU window systems offer improved thermal performance, reduced heat loss and better comfort compared to older installations.  Trade Window & Door Insights | Installer Blog | Fenster Trade Frames
