Create a brighter environment, save on energy costs, and earn LEED credits with the durable and superior engineering of our LIGHTWALL 3000 curtain wall system.
The LIGHTWALL 3000 accepts both insulated glass and cellular polycarbonate panels. This can be done within the same framing system – a function that perhaps no other curtain wall system can accomplish. The additional benefits of daylighting are present with the LIGHTWALL 3000 system and can be used for a wide variety of environments and applications.
