When designing an insulating unit with a laminated component, where should the laminate be positioned, closer to the exterior/outside elements or towards the building interior?
Viracon recommends that the laminate be supplied to the interior or inboard of the insulating glass unit. Since the laminate is the protection piece and most often the intent is to protect potential victims on the interior of the space, the laminate should be closest to the victim side. In addition, typically when designing with an insulating unit often a high performance coating will be incorporated for enhanced thermal performance. The fact that sputter coatings perform best on the #2 surface of an insulating unit vs. when encapsulated within a laminate, the exterior ply is recommended to be monolithic with the high performance coating on the #2 surface to achieve maximum thermal performance.
