the wtz5500 takes up thermal and structural movement (the movement for each size is in the profile specifications below) while the cover stays seated on both sides of the joint.
the cross-section reveals the punctureless epdm/tpv water barrier integrated below the hinged pan assembly, connected to the adjacent waterproofing membrane for complete watertightness.
the wtz5500 under traffic, rated for heavy pedestrian and light vehicular traffic. the load capacity of each size is in the profile specifications below.
with tile or carpet laid into the recessed pan and the aluminum hinge cover flush with the finish, the joint all but disappears from view in premium front-of-house floors.
The recessed centre pan takes the surrounding floor finish, so only slim aluminum lines stay visible, shown here in marble, porcelain tile and polished concrete.
