Thermalight Sliding Rooflight

Thermalight Sliding Glass Rooflight

Thermalight Sliding RooflightThe Thermalight Sliding rooflight helps bring the outside in, for true unobstructed light and ventilation when the unit is in the open position.

The unit’s in-built telescopic sliding mechanism has been designed so that the rooflight can support its own weight without the need of roof tracks or additional obtrusive supports.

The opening mechanism is a rack and pinion drive with a 24V electric motor that is neatly concealed within the framework to ensure optimum daylight into the space below. The motor is controlled using a touch sensitive switch that allows precise movement of the sliding rooflight. Optional extras include: rain sensor, temperature sensor, remote control units, and a safety access control (PIR) sensor.

In the event of a power failure whilst the rooflight is in the open position, a manual override facility, including a key, can be used to disengage the motor allowing the rooflight to be opened and closed manually.

The units are easy to install and are supplied with a unique internal perimeter gasket that allows the rooflight to be positioned and screwed externally onto the builder’s kerb and a matching cover clip is then applied to conceal the fixing – no need for silicone to be applied on-site. A qualified electrician will be required to connect the motor and transformer switch. Wiring diagrams/instructions are supplied with all Thermalight electrically opening rooflights.

The unit’s extruded thermally broken aluminium frame is dual coloured as standard, and supplied powder coated to RAL 7016 (Grey Outer) and RAL9910 (White Matt Inner). Other RAL colour options are available upon request.
