Glazing vision have adopted their pioneering frameless design ethos with this product so that when installed the building occupants can enjoy sky only views from the roof window something not usually found with traditional roof window products. Sliding over roof skylight sliding over roof skylight for larger areas with sufficient unobstructed roof space for the sliding section you should consider a sliding over roof skylight.

Typically the top side of the skylight well runs at 90 degrees to the roof slope and the bottom side if splayed is framed plumb see figure 3 20. With this skylight the glazed section slides as a single leaf and is supported by tracks on the roof itself in the open position. When using manufacturer produced curbs that aren t tall enough the roofing professional will have to extend the curb. On very steep roofs where the top of the skylight is near eye level a horizontal angle works well for the top side of the well.

If the skylight is installed on a low slope roof the curb should be even taller to allow for 8 inches of flashing.
