Laminated Hurricane Impact Resistant Glass is comprised of two sheets of glass bonded together with a protective interlayer. Laminated glass is the primary hurricane barrier used in impact resistant windows. Laminated glass is also used in the windshields of cars and bulletproof glass.
Insulated Laminated Glass adds an extra single pane of glass to the laminated glass unit with a sealed gas filled space in between. This glass offers greatly enhanced energy performance.
Insulated laminated glass improves the performance of LoE coatings and in some cases architects or local building departments are requiring its use.
