Feature Glazing
Engineered overhead glass for when it carries load, turns a corner without a post, or brings daylight down through a floor.
- Walk-on loading
- 5.0 kN/m²
- Glass beam
- To 4500 mm span
- Lead time
- 6–8 wks + sign-off
- Glass roof links to 3500 mm wide
- Anti-slip frit on walk-on panels
- Signed off by our structural engineer
The whole feature glazing square on and filling the frame, in the walk-on floor panels configuration, shot level in flat overcast light against a plain wall so the proportion and the frame-to-glass ratio can be read without perspective.

Close detail of the meeting line at eye level in raking light, tight enough that the joint and the seal are legible, with the background thrown out of focus.
1:1
The hand-level detail: concealed structural carriers photographed in use on the frameless finish, close enough to show the surface texture and the fixing, with a hand on the handle for scale.

From inside the room looking out through the feature glazing, the unit open where it opens, late afternoon light on the floor, so the product is seen the way it is lived with rather than the way it is sold.

The feature glazing at dusk from outside, closed, the room lit behind the glass, so the finish and the glass line read against the light.

Specifications & options
Feature Glazing
Description
Feature glazing is the work that gets engineered rather than ordered. Walk-on floor panels to 1800 x 3000 mm at 5.0 kN/m2, built as a 10 mm toughened top layer over two 10 mm heat-soaked laminated plies. Mitred roof-to-wall corners with no post. Glass roof links to 3500 mm wide and 6000 mm long. Structural glass beams spanning 4500 mm in three 15 mm laminated plies. Every job carries calculations to BS EN 1990 and BS 5516-2 signed by our structural engineer. Add about two weeks for that sign-off before manufacture starts.

The detail carries load, turns a corner without a post, or lets daylight into a basement through the floor above.

1:1More in roof systems
Interior on an overcast morning, shot from a stepladder at the edge of the opening so the glass meets the plaster line with no frame between them and the 4000 mm run of the pane recedes across the top of the frame.

Rooflights
Kitchen at dusk with a chain-actuated skylight held half open, the actuator arm and its 300 mm stroke readable against the darkening sky, steam from the hob drifting up through the opening.

Skylights
Low interior angle across a laid dining table towards a hipped ridge lantern in late-afternoon light, so the 40 mm rafters read as a grid of thin lines and the ridge runs out of the top of the frame.
