Laminated Glass: Laminated glass consists of two lites of equal thickness (¼") bonded together with a polyvinyl butyral (pvb) interlayer. In the event that the glass should break, the pvb interlayer will allow the glass to remain in the skylight frame. Heat-strengthened glass is twice as strong as regular annealed glass and is used in all e-skylight.com skylights.



Insulated Glass: Insulated glass consists of a ¼" thick, heat-strengthened outer lite, over a ½" dual sealed airspace, over a heat strengthened, laminated inner lite (thickness to be determined based on size of lite). Because of its inherent thermal properties, insulated glass is typically used over a conditioned space, where energy efficiency is of paramount concern.



PPG Solarban 60^TM:  Specifically designed for heating dominated climates, PPG Solarban 60<sup>TM glass reduces heat loss by reflecting heat back into the space, maximizing energy efficiency and reducing heating bills.



PPG Solarban 60TM:  Specifically designed for cooling dominated climates, PPG Solarban 60TM Solar Control glass reduces unwanted solar heat gain by rejecting a siginifcant portion of the sun's solar infrared energy back to the outside, helping to keep homes cooler and lowering cooling costs in the summer.
