Aluminium Sliding Doors
Slim sightlines. Large openings. Controlled installation.
Aluminium sliding doors are a defining feature of many London extensions and contemporary refurbishments. We specialise in slimline sliding systems designed to maximise glass area while maintaining smooth operation and strong thermal performance.
Our sliding door range includes options suited to:
– Large structural openings
– Minimal interlock sightlines
– Everyday family use
– Complex configurations, including corner and pocket doors
Sliding doors are always specified in relation to structure, finished floor levels, and intended use, ensuring long-term reliability rather than short-term visual impact.
Corner & Pocket Sliding Doors
Open the corner. Keep the structure clean.
Corner sliding pocket doors allow two panels to meet at an open corner without a visible post, creating a seamless connection between inside and out.
When open, panels slide fully into concealed wall pockets, leaving a clear, uninterrupted opening.
These systems require early coordination with structure and build-up details and are best suited to projects where design intent and planning are considered from the outset.
Aluminium Bifold Doors
Flexible openings, specified properly
Aluminium bifold doors remain a popular choice for UK extensions and side returns, offering flexible opening configurations and strong thermal performance.
We offer a small selection of bifold systems chosen for:
– Reliable daily operation
– Clean sightlines
– Appropriate panel sizes
– Long-term alignment
Bifold doors are specified carefully to suit opening size, usage patterns, and threshold requirements, with honest advice given where alternative systems may be more appropriate.
Heritage Aluminium Doors
Traditional appearance, modern performance
Heritage-style aluminium French doors offer the visual proportions of traditional steel or timber doors with the benefits of modern aluminium construction.
These systems are well suited to period properties, conservation-sensitive projects, and extensions where traditional detailing is required without compromising performance or durability.
Aluminium Windows
Slim profiles, clean integration
Aluminium windows are ideal for projects where slim sightlines, strength, and durability are required. We install aluminium windows as part of extensions, refurbishments, and new-build homes across the UK.
Our window systems are specified to suit the architecture of the property, whether contemporary or heritage-led, and installed with careful attention to structure, tolerances, and junction detailing.
Aluminium Entrance Doors
Security, design, and durability, properly specified
Aluminium entrance doors provide a strong, secure, and visually refined entrance to a property, combining modern performance with long-term durability. The Fenestration Network supplies and installs aluminium entrance doors for UK homes where appearance, security, and reliability are equally important.
Our entrance doors are specified to suit the architecture of the property, whether contemporary or traditional, and integrated carefully into the surrounding structure to ensure consistent alignment, weather performance, and a clean finish.
