Note: We have calculated our dome system without using the added structural strength contributed by our 3/4” plywood exterior panels. This allows us to install skylights in any or all of the exterior panels. Normally, our domes have 8 to 12
skylights, which is approx 10% of the roof area. The structural load calculations would be greatly enhanced if the 3/4” plywood exterior panels were factored into the engineering calculations. Using the exterior panels as part of the strength and our Ultra-Lok connectors, our domes can take snow loads in excess of 150#PSF or winds in excess of 200 MPH.
Notes: Additional engineering costs will be incurred if your local building
department wants engineering certification of non-dome shell components, such
as footings, foundations, floor systems, interior support walls and like items. Natural Spaces Domes Ultra-Lok connectors will meet building codes in areas with high winds (coastal), heavy snow (mountains), and earthquakes. |
