Without a doubt rooflights improve the look and feel of your internal spaces. They add valuable extra natural light and offer compelling sky views. A rooflight positioned above a dining or seating area creates an uplifting focal point for a new extension and works with large sliding doors to create a beautiful light-filled space.

Contemporary aluminium frameless rooflights

Our aluminium rooflights are designed to be elegant and minimal. They are bespoke to individual homes and are built to order. With dimensions up to 4 or 5 metres in length they add drama to any extension.

Whether they are fixed roof lights or opening models, roof light windows can be fitted with solar control glass to minimise UV fading or tinted or obscured glass for privacy.

Installed in flat roofs and pitched roofs between 5 and 45 degrees, they have a small upstand to allow weatherproofing around the frames and keep the structure weathertight. They are energy-efficient, double or triple glazed units with exceptional thermal performance and water tightness.

Rooflights also provide important ventilation and access to terraces and balconies. The ODC Electric Opening Rooflight can be installed on roofs with a minimum pitch of 5°and a maximum pitch of 45°. It has an upstand height of a minimum 150mm. It can be installed with a fully automated opening mechanism.

We also offer hinged access rooflights, sliding rooflights, fire rated pyramid and lantern rooflights. Our Access Rooflights are high specification, safe access models where easy exit to a flat roof is required.

What are lantern rooflights?

Rooflights that extend up into elegant glazed pyramids and long atrium structures are stylish architectural focal points and bring superb light transmission to interiors. Once a classic feature of period homes, you can opt for glass roof lanterns in a contemporary style. Whether heritage or minimalist in design, both are available in custom-made dimensions to suit your home.

Customised flat rooflights for extensions

Bespoke rooflight designs make a huge difference to the success of our customer projects. Flat rooflights extend living spaces without losing light levels in existing areas. Multiple rooflights create an atrium effect for an extension and a single large rooflight draws natural light down to a kitchen, dining or seating area.
