Insulating Glass & Glazing Sealants
High-performance glazing sealants engineered to support insulating glass durability, window and door manufacturing, exterior weatherproofing, and long-term fenestration system performance.
High-Performance Glazing Sealants Engineered for Long-Term Durability
Quanex glazing sealant technologies help manufacturers, fabricators, and glazing professionals support insulating glass durability, streamline production processes, and improve long-term sealing performance across demanding fenestration and exterior sealing applications.
Supporting Performance Across Glazing and Insulating Glass Applications
Glazing and insulating glass sealants play a critical role in the long-term performance, durability, and energy efficiency of modern window, door, and fenestration systems. From moisture resistance and movement accommodation to manufacturing efficiency and environmental durability, sealant performance can significantly influence both fabrication outcomes and long-term field reliability.
Quanex offers a range of butyl and silicone glazing sealant technologies engineered to support insulating glass manufacturing, window and door assembly, exterior weatherproofing, and fenestration sealing applications. Designed for compatibility across a variety of substrates and production processes, Quanex sealants help manufacturers and installers maintain performance without sacrificing operational efficiency.
Modern glazing, insulating glass, and fenestration systems demand high-performance sealants capable of supporting long-term durability, environmental resistance, manufacturing efficiency, and reliable adhesion across a wide range of materials and operating conditions.
-
Moisture Resistance
Low moisture vapor transmission performance helps support long-term insulating glass durability and improve weatherproof sealing performance across building envelope applications.
-
Long-Term Flexibility
Sealants engineered for movement accommodation help maintain adhesion and sealing performance through thermal expansion, contraction, and changing environmental conditions.
-
Manufacturing Efficiency
Fast-setting and high-speed application technologies help window and door manufacturers improve throughput, reduce downtime, and support cleaner production environments.
-
Multi-Substrate Adhesion
Advanced glazing sealants are engineered to bond to glass, aluminum, vinyl, coated metals, masonry, wood, and other materials commonly used in modern fenestration systems.
-
Environmental Durability
UV resistance, weatherability, and thermal stability help support reliable long-term performance in demanding exterior glazing and building envelope applications.
-
Production Versatility
Compatible with manual and automated dispensing environments, Quanex sealant technologies support a range of fabrication processes across insulating glass, window, and door manufacturing applications.
