The use of skylights in industrial buildings should be limited due to their high cost and complexity of operation, the formation of snow bags and other disadvantages. In cases of application, light aeration lights should be designed with longitudinal U-shaped profiles.
Cross lights are allowed to be used in multi-span buildings only with the same span height and with appropriate justification.
In multi-span buildings with the same industrial hazards in all spans or in the spans of extreme and adjacent spans, it is generally not recommended to arrange lights in the extreme spans if lights are not required for lighting.
Light and combined (for lighting and aeration) lanterns should be with vertical glazing and not blown out. With vertical glazing, wind panels should be provided only in cases where the ingress of atmospheric precipitation into the room, even in small quantities, is not allowed under the production conditions. The use of skylights with sloped glazing is allowed if there are special justifications. In skylights with sloped glazing, wind panels should be provided at both ends of each individually opening sash strap.
In multi-span buildings, the width of light and combined lights with double-sided glazing must be at least 0.3 of the width of the span illuminated by the light.
The distance between adjacent glazed surfaces parallel to the same level lamps with double-sided glazing must be at least:
one and a half sum of heights of adjacent lanterns - with vertical glazing;
the sum of the heights of adjacent lamps - with inclined glazing.
In multi-span buildings, combination lights should generally be installed at the same height in all spans.
The distance between the glazing of the lantern and the wall parallel to the lantern must be at least one and a half the height of the lantern, and the height of the wall should not be more than double the height of the lantern. In case these requirements cannot be met, it is recommended to use lamps with one-sided glazing facing away from the wall. The distance from the ends of the light and combined lanterns to the outer walls of the building or walls located at elevation differences should be taken, as a rule, at least 6 m.In some cases, if justified, this distance can be reduced to 3 m.
In skylights with windbreak panels, it is recommended to provide removable transverse partitions between the lantern and the windbreak panel approximately every 100 m. The same partitions are installed at the ends of the lanterns.
In multi-span buildings, if the lanterns are located in parallel and their top is at the same level, and the distance between them does not exceed five times the height of the lantern, to ensure that the lanterns are not blown out, windproof panels should be provided only on the outside of the end lanterns or the outer openings of the end lanterns should be filled with blind bindings.
The lower edge of the glazing of the skylights must be at least 300 mm above the level of the adjacent roof.
In skylights, breaks with a width of at least 6 m (in the axes of structures) or transitional fire escapes should be provided along the length of at least 84 m.
