This laminated piece of glass allows you to demonstrate the performance, appearance, and construction of laminated glass that is commonly used in hurricane windows. The glass is comprised of two pieces of 1/4" glass with a 0.090" PVB laminate in between. The resulting dimensions are 7 x 7 x 0.54 inches. There are no coatings on the glass. This glass sample is supplied without the protective white vinyl wrap on the perimeter, so the customer can see the cross section of the laminated glass.
