Application and Function
Surface joints must be placed within the tiled surface regardless of substrate conditions. They provide stress relief from movements in the tile field due to thermal and moisture expansion/contraction and loading.
Schluter-DILEX-KSN is a pre-fabricated, maintenance-free surface movement joint profile. It features trapezoid-perforated anchoring legs, made of stainless steel, solid brass, or aluminum, which are secured in the mortar bond coat and provide edge protection for adjacent tiles.
The profile separates individual fields in the tile covering and accommodates movement via the 7/16" (11 mm) wide, soft thermoplastic rubber movement zone, which also forms the visible surface. The thermoplastic rubber movement zone can be replaced if damaged.
DILEX-KSN, with solid brass or stainless steel anchoring legs, offers secure edge protection for surfaces exposed to heavy-duty commercial traffic (e.g., warehouses, production facilities, or shopping malls).
Schluter-DILEX-EKSB, featuring stainless steel anchoring legs, is available in 3/32" (2.5 mm), 3/16" (4.5 mm), and 1/4" (6 mm) heights to accommodate thinner floor coverings (e.g., VCT flooring or coatings). DILEX-EKSB is appropriate for residential to medium-duty commercial applications.
Note: The thermoplastic rubber movement zone for DILEX-EKSB is not replaceable.
