Curtain Wall Waterproofing
Specialist sealing and waterproofing for glass curtain wall and aluminium cladding systems.
Overview
Glass curtain walls are the defining architectural feature of Singapore’s commercial skyline — but they are also among the most failure-prone building envelopes when maintenance is neglected. Sealant degradation, gasket failure and joint movement combine to cause persistent water ingress that can damage interiors and corrode structural fixings.
Form & Function provides full lifecycle curtain wall maintenance: condition surveys, sealant replacement, gasket repair, anchor point sealing, and full facade inspection reports compliant with BCA Periodic Facade Inspection (PFI) requirements.
Our specialists are trained in working at height on glass facades, with full understanding of curtain wall mechanical systems, drainage paths and pressure equalisation principles. We use only specified silicones from Dow Corning, Sika and Bostik with proven 20-year performance histories.
Whether you are addressing a known leak, planning preventive maintenance, or preparing for a PFI submission, our team can assess your facade, scope the works required, and execute the repair to minimise disruption to building tenants.
