National Park Service
Arches National Park is a U.S. National Park in eastern Utah. It is known for preserving over 2000 natural sandstone arches, including the world-famous Delicate Arch (featured on many Utah license plates), in addition to a variety of unique geological resources and formations.
The park is located just outside of Moab, Utah, and is 76,679 acres (31,031 ha) in area. Its highest elevation is 5,653 feet (1,723 m) at Elephant Butte, and its lowest elevation is 4,085 feet (1,245 m) at the visitor center. 43 arches have collapsed due to erosion since 1970. Administered by the National Park Service, the area was originally created as a National Monument on April 12, 1929. It was redesignated as a National Park on November 12, 1971
Several years ago the park contracted to have informational exhibits installed with maps and various examples outside the building entrance. This included erecting a canvas shade structure to protect the exhibits and the visitors from the harsh summer sun. Within just a few years the canvas was tattered by the wind and needed replacement with a long term solution that could be opened in the winter to let the snow fall through and closed at different angles in the other months to provide the necessary shade.
Design and Key Factors
The engineers at Arches searched for a shade cover that would provide long-term solutions but yet blend with the surroundings. It needed to be functional enough to adjust in different times of the year. They evaluated several types of covers and settled on louvered roofs as the answer. The bid was put out for a metal louvered roof that could be designed with many angles that would closely match the canvas layout and utilize the existing pillars and beams. It was important to match the existing building and frame structure colors to make it blend in and needed to have a high wind rating.
American Louvered Roof Systems manufacture an extruded aluminum product that can be rated up to 180 mph wind load and has a power-coated finish in colors that match extremely well. The louvers could be cut to match the angles in the original design. The adjustability of the louvers with just a touch of a button on the remote control was the perfect solution to their needs. The engineers designed the louvered roof to the specifications required and the bid was submitted, awarded and the product installed. The installation took about 3 weeks to complete. It is said to be the largest louvered roof in the nation and has 10 independent motors with rafters reaching almost 100’ long and louvers nearly 22’ long.
The benefit to the park is that in the hot months the louvers provide complete shade and great ventilation at the same time (the louvers are parallel to each other). In the winter months the louvers can be left open to keep the snow from building up on them or closed to provide protection from the elements.
