Double Laminated Insulating

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

Double laminated insulating glass units have both a laminated inboard and laminated outboard with a space in between. This configuration is often selected when improved OITC acoustic performance is desired such as in schools. In addition, double laminated insulating units can meet protective glazing requirements.

Glass characteristics

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

There are eight surfaces in a double laminated insulating glass unit and two primary options for Low-E or Reflective coating placement within the unit. Coatings placed on the #2 surface decrease solar heat gain; however, superior solar performance, including an improved u-value, is achieved by placing the coating on the #4 surface, touching the air space. For additional information regarding Saint Gobain coatings, see the coatings page within components.
