Sliding over Fixed rooflight is usually split into two sections, with one sliding pane of glass moving over a fixed section. This configuration allows the maximum amount of light to be transmitted whilst opening up 50% of the overall footprint for ventilation. Power is transmitted through a twin drive rack and pinion system with large diameter carriage wheels and hard anodised tracks to provide smooth travel when in motion.

Unit features a one way solenoid clutch and built in anti lifting mechanism so the sliding section cannot be forcibly back driven. Qualicoat approved polyester powder coated frame is supplied dual colour as standard and is thermally broken using 39 mm polyamide thermal breaks and closed cell PIR insulation. Improved thermal performance can be achieved by specifying triple glazing which is now a standard option.

This rooflight can be supplied with a laminated inner pane which has been attack tested to LPS2081 Issue 1: 2015 and rated Secured by Design.
