| Petroleum Dome
The Ultradome is a fully triangulated, spherical, spaceframe structure designed to be self-supporting from its periphery. Primary horizontal thrust is contained by an integral tension ring. The framework is covered with attractive non-corrugated aluminum panels.
Lapped Vs. Batten
Ultraflote is the only dome manufacturer that supplies two types of panel attachment systems: A lapped panel design and a batten design. Both systems offer unique advantages. The batten system is best suited to applications where a pressure tight dome is necessary. The lapped system is used where a weather tight structure is require and a long, maintenance-free life is expected.
At first glance, the Ultradome may appear very similar to other competitive products. Actually, it includes many unique features. Probably the most obvious is our lapped panel joining system which completely eliminates the need for rubber sealing strips and caulking compounds of any kind. Instead, our panel edges are downhill lapped and fastened on six inch centers with #14 weatherguard washer equipped 300 series stainless steel screws. This system has a proven history of success in the metal building industry for many MANY years.
HERE FOR ANIMATION
Such etching is, of course, impossible under field conditions. Even simple cleaning to remove mill oil and dirt is difficult. Also, most sealant manufacturers caution not to apply their products below 50 degrees F and not when the surface is wet or dewey. These conditions are difficult to insure in the field, especially in cooler weather.
We also avoided using "rubber" sealing strips (that are not enclosed) which are relied upon by other designs to seal the panel edges as well as clamp them securely. The LONG term effects of sun, weather, time and pressure are not completely known, even for systems which have been in service for many years.
The Ultradome lapped panel system has none of these potential problems. The downhill laps rely on gravity to keep water out just as traditional roofing systems have for hundreds of years. The weatherguard style washer is a neoprene rubber washer covered by a dished stainless steel or aluminum washer to protect it from the environment and assure uniform pressure. This fastener is the standard of the metal building industry and has been proven in that industry for many years. This simple approach provides a weatherproof joint system that will remain weathertight throughout the life of the dome.
when an airtight system is required, our Batten Seam design is the appropriate
This design uses a batten bar to hold the panels and elastomer strips and silicone sealant to make a weather seal. The design incorporates four continuous solid silicone o-ring type cords, which are fully enclosed by the batten bar and are under uniform compression to ensure maximum sealing efficiency. The use of highest quality silicone o-ring material and sealants in the Quad Seal Batten Seam help produce the lowest profile batten bar in the industry.
With the batten seam the panels interlock with metal-to-metal clamping to ensure maximum panel strength. In addition, the extruded groove in the beam web allows sufficient depth of thread engagement to develop maximum strength of the panel fasteners.
