EC2 JC is a panel made up of two outer longitudinal plies, enabling it to be installed by mechanical fastening at the bottom of a hollow joint under a primary framework.
The panels are installed edge-to-edge or not on the short side, and overlapping on the long side to create a hollow joint. Non-disassembled, these self-supporting trays on concealed framing ensure sturdiness of use and a flowing appearance for your ceiling.
