Skylights
An opening rooflight for rooms that need ventilation, on roofs from flat to 75 degrees, with an electric option that shuts itself when it rains.
- Opening leaf
- To 1500 x 2500 mm
- U-value
- From 1.2 W/m²K
- Lead time
- 6–8 wks
- Rain sensor on the electric unit closes it
- Electric or manual opening
- Thermally broken aluminium frame
The whole skylights square on and filling the frame, in the electric chain-opening 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. Unit at 1500 x 2500 mm.

Close detail of the meeting line at eye level in raking light, tight enough that the joint and the seal are legible and the Thermally broken aluminium, 68 mm sightline sightline can be measured off the frame, with the background thrown out of focus.

The hand-level detail: 24 v chain actuator photographed in use on the 213 ral colours plus anodised 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 skylights, 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.

Skylights
Description
A skylight opens. Sharp fits chain-actuated and manual units to roofs from flat to 75 degrees, with an opening leaf to 1500 x 2500 mm and a 68 mm frame sightline. The 24 V motor drives the leaf shut in 18 seconds and the rain sensor triggers it within eight seconds of first contact. The leaf glass is lighter than a fixed pane at 6 mm toughened over 6.8 mm laminated, which is what keeps it inside the actuator's duty. On a flat roof it sits on the same 5 degree kerb a rooflight needs.
Specify it when
A bathroom, kitchen or loft room that needs ventilation and heat purge overhead, or a pitched roof where a bonded pane cannot be used.

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
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.
