Schluter DILEX-BWA Perimeter Joint Movement Profiles

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.

  1. Select Schluter-DILEX-BWA according to tile thickness.
  2. Using a notched trowel, apply thin-set mortar over the area where the profile is to be placed.
  3. If necessary, fill the dovetailed channel with Schluter-KERDI-FIX, epoxy resin, silicone, or similar to adhere the profile to the existing structure.
  4. Press the perforated anchoring leg of Schluter-DILEX-BWA into the mortar and adjust it securely against the existing building elements.
  5. Trowel additional thin-set mortar over the perforated anchoring leg to ensure full coverage and support of the tile edges.
  6. Solidly embed the tiles and align flush with the top of the profile.
  7. A joint of approx. 1/16" - 1/8" (1.5 mm - 3 mm) should be left between the tile and the profile.
  8. Fill the joint completely with grout or setting material.


Schluter-DILEX-BWA consists of a trapezoid-perforated anchoring leg made of recycled rigid PVC, connected by soft CPE movement zones to a dovetailed channel, also made of recycled rigid PVC.

In special cases, the suitability of a proposed type of profile must be verified based on the anticipated chemical, mechanical, and/or other stresses.

Schluter-DILEX-BWA is resistant to most chemicals encountered in tiled environments. The profiles CPE movement zones are UV-resistant and contain no softeners. The CPE material is also resistant to a number of acids, alkalis, oils, greases, and solvents.


Schluter-DILEX-BWA requires no special maintenance and is resistant to mold and bacteria. Clean profile using common household cleaning agents.
