KEY INFORMATION & PROJECT DETAILS

KEY INFORMATION:

Project name: Glazing restoration - Remediation for leaky penthouse windows

Client: Imperial Plaza

Location: Honolulu, Hawaii

Services Provided: Leak Investigation, Window Replacement, Historic Preservation

The ChallengE

Addressing Persistent Water Intrusion

Over time, Hawaii's tropical climate—characterized by intense UV exposure, high winds, and salty air—compromised the integrity of The Imperial Plaza's glazing system. Sealants and gaskets deteriorated, leading to persistent water intrusion, especially at the intersections of sloped and vertical glazing and adjoining concrete elements. These leaks not only disrupted residents but also raised concerns about potential structural damage and mold proliferation.
