MODULAR ROOFLIGHT CASE STUDY · HAMPSHIRE

Wraparound wall-abutted rooflight
Hampshire cottage

Overhead Glazing designed, supplied and installed a bespoke double-glazed rooflight for a cottage near Southampton and Winchester. The modular glass follows two sides of the existing walls, with a mitred corner and a 1 m clear width between upstands.

THE PROJECT

An L-shaped glass rooflight for a Hampshire cottage

The rooflight sits against the existing cottage walls and turns a corner above the kitchen and sunroom. Anthony Warren Associates was the architect for the project.

The brief called for a 1 m clear opening between upstands and as few visible glass joints and glazing bars as practical. The pane sizes and support layout were coordinated around that opening and the change in direction.

ARCHITECTURAL CONTEXT

The architectural plan shows the glazing turning the corner between the kitchen and sunroom.

PROJECT BRIEF

How the glazing follows the building

The panel layout had to work along both walls and through the corner, where the two runs meet.

Follow the existing walls

The bespoke rooflight was shaped around the two adjoining elevations.

Keep a 1 m clear opening

Structural laminated glass and a coordinated support layout helped limit the need for additional glazing bars.

Carry the glazing around the corner

A mitred corner and consistent silicone joints maintain a continuous line across the two runs.

GLASS AND FRAME SPECIFICATION

Solar control glass and thermally broken frames

The double-glazed units combined a solar control outer pane to help limit glare and solar heat gain with a low-emissivity coating to reduce heat loss.

Thermally broken aluminium frames supported the units around the perimeter. The glass specification included structural laminated glass to suit the opening and support arrangement.

FROM DESIGN TO INSTALLATION

Templating the mitred corner on site

Set out the glass panels

Overhead Glazing coordinated panel sizes and supports with the wall lines and clear opening.

Install the perimeter frames

The aluminium frames established the supporting edges for the glazed units.

Template the corner

The team templated the mitre after the frames were installed so the glass could be made to suit the fitted frame.

Fit and seal the glazing

The panels were fitted with consistent silicone joints along the two runs and at the corner.

THE OUTCOME

Daylight along both sides of the cottage

The completed rooflight follows the cottage walls through the corner. It brings overhead daylight into the kitchen and sunroom while keeping the panel divisions to a minimum.
