Calvary Church

Petersen Aluminum

The design for a major renovation and expansion of Calvary Church in Naperville, IL centered around utilization of Petersen Terne Coated Stainless Steel panels for dramatic effect. The project was initiated when the existing pre-engineered building could no longer meet the needs of the congregation. The architectural collaborative of Goss Pasma Blomquist Architects, Iron Mountain, MI was hired to direct the design. The firm specializes in churches and religious facilities.

More than 16,000 sq. ft. of 26 gauge Petersen TCS Flat Seam Panels were used to clad the walls of the dramatic structure. The roof utilized 12,000 sq. ft. of PAC-CLAD 22 gauge, 16” O.C., Tite-Loc Plus panels finished in Musket Grey.

“We were somewhat given a palette of material,” said Doug Pasma, design principal with Goss Pasma Blomquist Architects. “The existing pre-engineered building had lots of metal with a brick package at ground level. While we wanted to stay within the family of material for the expansion, we clearly sought to integrate an inviting, contemporary design. The lapped TCS panels added nice texture and provided a very forward-thinking look.”

The TCS wall panels were complemented with the Musket Grey Tite-Loc Plus panels on the roof. Peterson’s Tite-Loc panels provide structural panel performance with architectural panel aesthetics.

Installation of the wall panels was completed by A-1 Roofing Company, Elk Grove Village, IL. James Mansfield & Sons, Inc., Lyons, IL, was the metal roofing contractor.

The construction manager on the project was Paul H. Schwendener, Inc., Westmont, IL.

Produced in factory formed lengths up to 55 feet, Petersen’s PAC-CLAD Panels are Herr-Voss corrective leveled to provide superior flatness. Longer lengths are available by consulting the factory. All are available in 36 standard colors on steel and 34 standard colors on aluminum.
