Product Overview

Sliding flat rooflight

Key Features

  • Make your room light and airy with a dual-function, sliding skylight. Designed to maximise daylight, whilst the slide-opener provides cooling airflow without the need for additional roof vents.

  • Perfect for bathrooms or kitchens where you need to manage steam or cooking smells. Our opening skylights also offer exceptional heat retention and thermal performance during colder periods.

  • During periods of strong sunlight, the addition of an optional blackout blind will allow you to air your room without excessive or uncomfortable glare from the sun.

  • The upstand will need to be pre-weathered (flashed in) which can be done with your chosen roof membrane or a separate flashing kit. This is not the responsibility Roof Maker and will need to be completed by your builder or roofing contractor.
