A structurally sound and energy-efficient curtainwall from Wausau
Window and Wall Systems, of Wausau, Wis., is being installed in
the Des Moines Federal Building. The new system was designed to
adhere to heightened security measures mandated by the U.S. government
while maintaining the aesthetics of the architect's design.
Once the General Services Administration (GSA) determined that
replacing the Federal Building's façade was the only way
to fix the building's leaks, it decided to renovate the entire
exterior of the 11 story building using energy-efficient technology.
According to a press release from Wausau, custom systems were
developed for all sides of the building. The building's east and
west sides feature a modified RX series window wall, while the
south elevation displays an 8-inch deep unitized system with 3-inch
covers and factory-glazed Alpolic panels that were manufactured
to match the field-installed panels of other elevations. The custom
stacking, vertically glazed curtainwall used on the north side
of the building features a 12- by 6-inch reveal.
"The tenants are very excited about the renovation,"
said Dan Keagle, project manager for contractor Neumann Bros.
"Not only will the building be more structurally sound and
aesthetically pleasing, but the new system will also eliminate
the leakage problems and allow more light to enter the offices."
Des Moines Federal Building's exterior and interior upgrades
are scheduled for completion this fall.
