Application and Function

Perimeter joints are provided at restraining elements to accommodate movements attributable to changes in moisture, temperature, and loading. Schluter-DILEX perimeter movement joints are specifically designed to provide the flexible connection of tiled surfaces to fixed building elements (e.g., bathtubs, shower trays, countertops, and door and window frames.) and prevent sound bridges, thereby reducing sound transmission.

Schluter-DILEX-BWA features a trapezoid-perforated anchoring leg, made of recycled rigid PVC, which is secured in the mortar bond coat, and a dovetailed channel, made of recycled rigid PVC, which can be bonded to fixed building elements (e.g., door and window frames, bathtubs and shower trays, countertops, etc.) using Schluter-KERDI-FIX, epoxy resin, silicone, tile adhesive, etc.

The profile isolates the tile covering from the structure and accommodates movement via the 3/16" (5 mm) wide soft chlorinated polyethylene (CPE) movement zone, which also forms the visible surface. The lower CPE movement zone is slit to maximize the absorption of movement.

DILEX-BWA also prevents sound bridges, making it ideal for transitions in sound-rated floors.
