New Advances in Aluminum Roofing Allow for Timely, Efficient and Eye Appealing Finishes
As with any construction project, the most valued finished product is one completed on time with minimal safety and construction concerns as well as an aesthetically-appealing finish that will stand up to weather and natural wear. One growing solution to meet these needs is the use of aluminum for roofing and panels. In fact, Petersen Aluminum Corporation of Elk Grove Village, Ill., a pioneer in the development of aluminum as a roofing material, touts that though they offer a wide variety of roofing solutions, approximately 50 percent of material sold today is aluminum.
“We have seen an acceptance and growth in aluminum roofing and panels because of their ability to handle high winds and their light-weight construction reduces labor costs,” said Michael Petersen, President of Petersen Aluminum Corporation. “Further, aluminum is durable and offers designers a wide variety of architectural options.”
Case in point are three diverse projects recently completed using Petersen Aluminum PAC-CLAD® panels.
Countering High Winds
Designed by KRA Inc., Bluffton, S.C., the Sea Turtle Village Cinemas project was to be designed consistent with the “low country architecture” required by a local review board in Bluffton, S.C. To achieve the desired architecture, PAC-CLAD panels were chosen for the roofing portion of the project. A forest green and aged copper color was used to help the complex evaporate into the surrounding pine trees and to create an earthy tone. More than 33,000-square-feet of 24-gauge SNAP-CLAD™ Panels were utilized on the project, a five building multi-use complex.
According to David Swanson, President of Southern Roof & Wood Care Corporation of Hilton Head Island, S.C., the project had many challenges because it is located in a high wind zone. Aluminum roofing was chosen for this project because of the agility to withstand high winds.
“Recent innovations in panel design have served to significantly broaden the application range for aluminum panels and several aluminum profiles are now available from a number of manufacturers that carry the UL 580 Class 90 wind uplift rating”, said Petersen.
High wind requirements also were a key consideration for the new Science & Technology Building at the University of South Carolina’s New River Campus in Bluffton, S.C. Designed by Watson Tate Savory Architects of Columbia, SC., the selection of the optimal roofing material was easy. According to Michael Watson, principal, “We selected aluminum because of the campus’ coastal location. Aluminum is clearly the material of choice for that environment. And, we specified the Tite-Loc Plus Panels because of the high wind load requirements. The building has performed well and looks great, too.”
More than 30,000-square-feet of PAC-CLAD .032 aluminum Tite-Loc Plus Panels and Flush Panel soffit material finished in silver metallic were utilized on the building. Tite-Loc Plus Panels combine an attractive thin-rib profile with superior structural performance.
Creating a Signature Look
Aluminum is also a growing solution in other areas of the country. More than 90,000-square-feet of Petersen’s 22 gauge SNAP-CLAD™ Panels finished in custom color zinc gray and installed in multiple tiers helped create a signature look for the designer of Oklahoma’s Council on Law Enforcement and Training (CLEET) facility in Ada, Okla.
Situated on a 300 acre site, the facility was designed by PSA-Dewberry Inc. of Tulsa. The strength of the design was in the roof concept, according to Vic Thompson, PSA-Dewberry’s director of design. “The stepped or tiered roof design has almost become a signature look for us,” says Thompson. “We included the multi-tiered concept in the submittal stage and it was received very favorably. We wanted the building to have a low, sleek look that kept with the purpose of the facility, which is primarily to train men and women in various law enforcement capacities. The gray color was important to give the building a gunmetal image and the low profile of the roof creates an encased look almost as if it were a shield or armor.”
According to Thompson, the use of PAC-CLAD® paneling was chosen because it met all of the requirements and offered the desired finish. Further, the multi-tiered concept allowed for a low, sleek, horizontal profile.
“A higher pitch dilutes the design,” Thompson says. “Owners generally prefer metal roofs because of their performance. The stepped look provides an innovative design that combines well with the other attributes of metal.”
Petersen commented that aluminum is very “designer friendly” and works well in fabricating even the most complex designs. Further, he said, aluminum is easier to work with than steel and is generally available in a wider range of gauges than steel, thereby making it easier to co-ordinate fabrication of the various exterior metal components for your project. And, since aluminum is significantly lower in weight per panel than steel, in many cases, the contractor can use one installer instead of two. Finally, it’s easier to cut and work with in the field, which contributes to labor cost savings.
“Overall, PAC-CLAD roofs are favored because of design appeal, efficient installation and the complete construction and safety package they provide,” Petersen said. “We’ve had key architects tell us they prefer aluminum and use it every chance they get—particularly when they are working directly with building owners. They feel the additional cost of aluminum is inconsequential compared to the overall value enhancement of the project.”
