What We Fit

Every opening, engineered properly.

Windows

Casement, flush and tilt-and-turn windows in uPVC or aluminium, built for thermal efficiency and security.

Bifold Doors

Wide-opening bifold sets that fold flat to open a room fully onto the garden or terrace.

Sliding Doors

Slim-framed sliding and patio doors for maximum glass and minimal sightlines.

Crittall-Style Doors & Windows

Slim steel-look black frames for an industrial, architectural finish, in durable aluminium.

Heritage Doors & Windows

Sympathetic profiles for period properties, matching traditional sightlines without sacrificing performance.

Built On Trusted Profile Systems

We don't cut corners on what's inside the frame.

uPVC

Selecta Systems

Our uPVC windows and doors are manufactured on Selecta Systems profiles — chosen for their weather performance, thermal efficiency and long-term colour stability.

Aluminium

Stayfix

For aluminium windows, bifolds and sliding doors we build on Stayfix profiles — slim sightlines, strong thermal breaks, and a frame engineered to stay true for decades.

Bifolds

Cortizo

Our bifold doors are built on Cortizo profiles — slim, thermally efficient aluminium engineered for smooth-gliding, wide-opening sets that fold back cleanly.

Sliding Doors

Smart Systems

For large sliding sets we build on Smart Systems profiles — proven aluminium engineered for big spans, effortless glide, and minimal sightlines.

Vertical Slider

Victorian Sliders

For period properties we fit Victorian Sliders — vertical sliding sash windows that keep authentic sightlines while performing to modern standards.
