Clean Edges, Quiet Floors, Professional Results

The ARDEX UD 146 Edge Insulation Strip is the unsung hero of smooth, durable self-leveling installations. By separating walls from the leveling compound, it prevents cracking from expansion pressure, eliminates sound bridges, and gives every pour a sharp, finished edge. Its self-adhesive design speeds setup, while the flexible polyethylene foam conforms easily around corners, pipes, and columns.

Perfect for use in both residential and commercial projects, UD 146 ensures every ARDEX underlayment or screed system performs at its peak—long after the pour is done.

Why Tile Pros Trust It:

• Reliable separation: Prevents wall-bonding and perimeter cracks.

• Acoustic isolation: Dampens impact sound transfer through walls.

• Easy application: Adhesive backing sticks securely to most substrates.

• Professional finish: Creates a clean, level edge after trimming.

• ARDEX system match: Designed for ARDEX self-levelers and screeds.
