High-Performance Window Tape and Sealant Systems
Pro Clima supplies advanced window tape and sealing tape systems in NZ designed for sealing around joinery and façade penetrations. Our range includes window sill tape and sprayable sealant solutions that accommodate movement while maintaining a strong seal. These systems are compatible with membranes and common substrates, ensuring reliable adhesion. Used correctly, they help create continuous airtight and weathertight layers around window openings and penetrations, supporting building envelope performance and long-term durability.
Where Window Details Fail - And How to Fix Them
Window installations are often exposed to movement, weather, and construction tolerances that make sealing difficult. Standard solutions can fail under pressure, especially when dealing with wind-driven rain or shifting substrates. Using high-quality window sill tape and flashing tape helps create a flexible, durable seal that moves with the building. pro clima systems are designed to handle these conditions, maintaining airtightness and resisting water ingress even during construction phases.
For builders and façade teams across New Zealand, this reduces the risk of leaks, call-backs, and long-term damage behind cladding. When sealing around windows, flashing tapes provide a consistent and robust approach to critical joinery detailing.
Combined with airtight membranes internally and weathertight layers externally, Pro Clima solutions help protect the building envelope while improving energy efficiency and overall performance.
Built for Accurate Application on Site in New Zealand
Pro Clima window sill tape and sealant systems are designed to simplify weathertightness without compromising performance. Backed by testing and supported by Pro Clima’s NZ technical team, these systems help ensure window junctions and weathertightness junctions are sealed correctly the first time.
