wtz1685
supermate wt series
Introducing the WTZ1685
movement
the wtz1685 takes up thermal and structural movement of ±28% to ±33% while the cover stays seated on both sides of the joint.
integral punctureless water barrier
the cross-section reveals the integral epdm/tpv water barrier running continuously beneath the aluminum interlocking profiles - 100% watertight with no punctures, connected directly to the adjacent waterproofing membrane.
load bearing
the wtz1685 under traffic, rated vehicular. the load capacity of each size is in the profile specifications below.
seamless finished installation
recessed installation with internal tile finish keeps the profile flush with the surrounding floor, exposing only slim aluminum sightlines for areas with heavy-duty traffic.
Aesthetic Choice
The aluminum interlocking profiles sit level with the finished surface, shown here in concrete pavers, porcelain tile and polished concrete.
