Endurex 540
Product Description
The Endurex 540 insulated spandrel glass panel is a laminated composite consisting of ceramic-backed spandrel glass, an insulating core material and a finished interior. This solution provides a low cost, glazing option for all curtain wall, spandrel and window applications.

Endurex 540 panels can be produced in any thickness desired and with our full variety of insulation types in order to meet a specified insulating value. There is no panel substrate necessary for the face - the spandrel glass is sufficient. However, any of our standard substrates can be selected for the panel back. See Features and Benefits tab for more details. If the panel back is visible, our full line of architectural finishes is available for the back of the panel in order to meet the desired look for the interior.
