Modular Rooflights are available in standard sizes and can also be configured, manufactured and delivered in bespoke sizes for specific requirements.
In venting modules, the actuator is fully integrated in the wooden upstand. The actuator is not visible from the inside when the module is closed, thus there is no visual difference between fixed and vented modules.
A venting module is operated by either one actuator or two synchronised chain actuators depending on the clear internal area and module width. The modules must be controlled by a separate Open System ± 24 V (OS ± 24 V).
