    Which installation do I need?

    PROUD | ON THE RAFTER

    When we refer to rooflight sizes, we use the structural widths and lengths that the rooflight will be fitted in to. The structural dimension is the clear opening that is required within the roof structure in order to install the product directly on to the rafters (main structural members making up the roof). We call this an ‘On The Rafter Installation’ or a ‘Proud Installation’. The rooflight height may be a little greater than the roof build up, so the rooflight may sit slightly proud of the roof level, however this still results in a beautiful external aesthetic for most roof types, especially traditional builds.

    FLUSH | BETWEEN THE RAFTER

    If you have a very low-profile roof build-up, like slate, the rooflight may sit noticeably higher than the roof level when installed on the rafters. If you want a completely seamless aesthetic externally, you could install ‘Between the Rafter’, to achieve a completely ‘Flush Installation’, meaning you can’t see the rooflight frame at all from the outside. This means that the framework for the rooflight to be installed on sits within and below the rafters. This type of installation requires a bigger structural opening to accommodate the whole rooflight.
