Seattle parking garage wall cladding


This unique project was designed to take an ugly, dirty-looking nine story parking building sitting in downtown Seattle and modernize its appearance while protecting the cars and people using the space from inclement weather.

An opaque wall was not an option for obvious reasons, including safety.
Some of the walls were curved.
All work had to be completed from the interior.
Deliveries at night and with low ceiling height restrictions.
Keeping parts of the structure open to the public to insure continued income for the owner.
Keeping the public safe and at bay.


Working closely with the architect and CPI Daylighting, Skylight Specialists, Inc. installed a very unique solution that met all the requirements and included solving some additional special challenges:

Acquiring all necessary licenses and building permits—no mean feat!
Accurately locating all existing handrail posts.
Installing the product from the interior required specialized equipment.
Maintaining straight and plumb installation—including a continuous curve—for nine stories.
Coordinating work with all other trades involved in the major overhaul.

24,000 sqf of a PentaClad™® single panel system weighing less than 2 lbs/sqf installed from the first to the ninth floors.
The ice white matte finish, standing seam panels were installed in reverse, providing a seamless flush look to the exterior—a “Times Square” look.
The PentaClad™ system design allows areas of the garage to be enclosed, while keeping others open for ventilation.
