Fixed Picture Windows — London & the Home Counties
30mm of aluminium, everywhere else glass
A fixed picture window has no gearing, no hinges, no meeting stile — just the outer frame. That's why our sightline drops to 30–45mm on a fixed aluminium picture window, versus 55mm+ on an equivalent opening sash.
Overview
When the glass is the design. A fixed pane in a thermally-broken aluminium frame with sightlines as slim as 30mm — up to 2.7m tall — the frameless-look window we sit above bifolds, between structural piers or at the head of a stairwell.
Thermally-broken aluminium profile (Smart Systems / AluK) · Qualicoat Class 2 polyester powder coat · argon-filled toughened double glazing · silicone-sealed structural glazing on request
Up to 2.7m Tall
A single fixed lite up to 2.7m tall and 3.5m² per panel with standard toughened double glazing. Larger sizes are possible with structural glass and site lifting.
30mm Sightlines
Ultra-slim 30–45mm sightlines on a fixed frame — up to 40% more visible glass than an equivalent uPVC unit.
No Moving Parts
Because they don't open, there are no hinges, gaskets or locking points to fail — a fixed picture window will outlast every other window on the property.
Above Bifolds & Sliders
The natural pairing for a bifold or sliding door — a fixed head light above brings full-height light without adding another opening door.

Practical answers.
Everything homeowners ask us about fixed picture windows — survey, lead times, guarantees and coverage.
How big can a fixed picture window be?+
Up to 2.7m tall and roughly 3.5m² per panel with our standard glass. Larger sizes are possible using structural glass with additional lifting equipment on site — we survey and quote separately for anything over that.
Can you fit one above bifold doors?+
Yes — a fixed head light above a bifold or slider is our most common configuration for full-height rear extensions. We coordinate the head detail, structural opening and colour match as one order.
Do fixed windows meet Building Regs for ventilation?+
A fixed window on its own doesn't provide ventilation, so Approved Document F requires another means of purge ventilation in the room. On a rear extension this is usually satisfied by the adjacent bifold or slider. We check the room-by-room ventilation plan at survey.
How do fixed windows differ from opening windows?+
Fixed windows have no gearing, hinges or opening gaskets, so they achieve slimmer sightlines and have fewer moving parts. They are ideal where another opening already provides ventilation.
