Product Description:
The ARDEX UD 146 Edge Insulation Strip is a professional-grade, self-adhering perimeter strip designed for use with ARDEX FLEXBONE uncoupling membrane and underlayment systems. Installed along perimeter walls, structural elements, columns, pipes, floor penetrations, and other fixed objects, UD 146 helps maintain the necessary separation between the flooring assembly and surrounding building components.
Designed as an essential accessory for ARDEX FLEXBONE installations, the UD 146 perimeter edge strip helps accommodate movement at the edges of tile and stone flooring systems. Proper perimeter isolation is important in uncoupling membrane, radiant floor heating, and tile installations because floors naturally experience expansion, contraction, and movement caused by temperature changes, structural movement, and normal building conditions.
The self-adhering design makes the ARDEX UD 146 easy to position around walls and penetrations before installing the FLEXBONE membrane. The adhesive backing helps hold the strip securely in place during installation, making it easier for contractors and tile installers to maintain a consistent perimeter separation throughout the flooring assembly.
ARDEX UD 146 is suitable for use with compatible ARDEX FLEXBONE underlayment and uncoupling systems, including applications involving tile, stone, and electric radiant floor heating. It is particularly useful around perimeter walls, columns, pipes, cabinets, structural penetrations, and other areas where the floor covering should remain separated from fixed building components.
For professional tile installers, flooring contractors, builders, and remodelers, the ARDEX UD 146 Edge Insulation Strip provides a simple and reliable way to complete FLEXBONE installations according to proper movement-joint and perimeter-isolation practices.
