Key Features

  • Triple-Layer Technology: A triple-layer pre-compressed and impregnated multifunctional design that handles the sealing of all function areas in a window joint—airtightness on the inside, thermal insulation in the middle, and driving rain resistance on the outside.
  • Expansion Power: Made from polyurethane soft foam, the foam expands in the joint to fill gaps perfectly. This polyurethane soft foam expands based on the degree of compression to provide a snug, reliable sealing of windows.
