The foamed-in camlocks ensure that CELLTHERM coldrooms are quick and easy to install. They eliminate the need for wrestling with corner or side posts or even time-consuming glueing and inefficient cutting of panels. The CELLTHERM "Passer-System" (adaptable fit) speeds up assembly still further. By means of the "Passer-System" panels can even be assembled upside-down, since all CELLTHERM panels have alternating tongue and groove profiles along their edges. Thus, you save time and money on assembly!
