Safety Laminated Glass

BIG GLASS CONFIGURATIONS AVAILABLE UP TO 130” x 236”. 

Laminated insulating glass is an insulating glass unit with a laminated outboard. This configuration can be used in applications where the exterior is overhead glazing or in specific hurricane zones where safety glazing is required for the exterior.

A typical laminated insulating glass configuration is 1-5/16” thick overall constructed as follows:

Glass characteristics

  1. Exterior: 2 plies of 1/4″ glass laminated together with a .060″ interlayer
  2. Interior: 1/4″ glass ply
  3. Coating on #2 surface
  4. 1/2″ airspace

It is important to note, with laminated insulating glass there are two primary options for Low-E or Reflective coating placement within the unit. Coatings can be placed on the #2 surface, however superior solar performance can be achieved by placing the coating on the #4 surface, touching the air space.
