It is recommended to have an area above the dome accessible from the attic or another room for easy access to the light fixtures and also to provide a stress free decorative glass skylight maintenance. Ideally it should be a deck built around the opening to allow a maintenance personal to access all skylight panels without putting up scaffolds. The walking area of the deck around the opening should be approximately 2 feet.
Air returned duct vents should be installed above the dome for proper ventilation. A gap between decorative mouldings and dome frame should be left to equalize air pressure.
Due to site specific details of each project it is Client's responsibility to approve structural details of the decorative skylight opening with structural engineer. The supporting metal frame may be attached to the rough opening beams using one of 3 variants
1. Steel frame is attached to the face of the rough opening beams. Usually it is planned for medium and small size skylights
2. Elevated and suspended on specially designed brackets, which are attached to the top surface of rough opening beams. Midium and large skylights
3. The metal frame is resting on the structural beams and anchored to the beams. This type of installation is planned for large and extra large leaded glass skylights
To achieve balanced artificial lighting during night time the glass must be lit by reflected from the ceiling and walls light. It is inadmissible to lit the glass panels by direct artificial light.
The color rendering index (CRI) is a quantitative measure of the ability of a light source to reproduce the colors of various objects faithfully in comparison with an ideal or natural light source.
Light sources with a high CRI are desirable in color-critical applications such a leaded glass skylight domes and ceiling
