Glazing Sealant Solutions

Structural Glazing
Structural glazing is a specialized architectural method that relies on high-strength, load-bearing glass or transparent materials to provide structural support for a building’s façade or envelope. In this approach, the glazing material goes beyond aesthetics and weather resistance, actively contributing to the structure’s stability. Properly chosen window sealant ensures a seamless, waterproof barrier, preventing water and air infiltration while offering structural support to the glazing unit.

Unitized Glazing
Unitized glazing is an advanced construction technique used in curtain wall and façade design, streamlining construction by enabling in-shop assembly of building components and reducing weather-related delays. This method requires specialized sealants with unique curing mechanisms to enhance manufacturing efficiency and sealant performance. Pecora’s Glass and Glazing Sealants offer primerless adhesion to most substrates and finishes, suitable for various components such as back bedding compounds, cap beads, end dams, and screw heads.

Transition Systems
Transition systems address areas where different glazing or framing materials intersect in a building envelope. These transitions are vital for preserving structural integrity, weather resistance, and aesthetics while accommodating diverse design and performance needs.

Restoration
Glazing system sealant failures are common issues that can lead to significant property damage over time. Glazing restoration involves repairing, replacing, or refurbishing components within the glazing system to enhance functionality, appearance, and performance. The choice of sealants for glazing restoration depends on the specific system, the extent of damage, building requirements, and desired aesthetics.


Non-Staining Technology™
Pecora’s Non-Staining Technology™ (NST) sealants are formulated to eliminate the free silicone molecules which leach out of the sealant and run down the surface of the glass. This effectively eliminates the possibility of unsightly staining and residue run down while increasing adhesion and reducing dirt pick-up. Pecora is proud to offer an extensive line of NST Glass and Glazing Sealants to protect your project and your reputation.
