Glazing Applications


Glazing Applications

Structural sealant glazing involves attaching glass, metal, or other panel materials to a building’s window or curtain wall metal framing system in place of using gaskets and other mechanical attachments. Only structural quality silicone sealants are used since they must be able to withstand ultraviolet radiation, weathering effects, wind load and other stresses, and transfer these affects to the metal framing system.
Typical Structural Glazing Design smaller

For effective structural sealant glazing joint design, the following structural joint parameters must be considered:

  • “Bite”—defined as the effective structural contact dimension of a structural sealant required on both the panel and frame faces to accommodate the required transfer of loads.
  • “Thickness”—defined as the minimum structural sealant dimension between structurally bonded substrates (the panel and frame) to facilitate the installation of a sealant and to reduce stress on the structural sealant joint that results from differential thermal movement.
  • “Deadload”—the weight that a panel places on a structural sealant joint when, for certain applications, no setting blocks are used to support a panel’s weight.

Pecora offers a complimentary Structural Glazing Appraisal Program, which is intended to reduce the risks for all team members. Compliance with the program is a requirement of all projects using Pecora structural silicone sealants.  Click here for more information regarding Pecora’s Structural Glazing Program.
