Many sizes are available:

  • Expanding foam tape for gaps between 1.5mm to 18mm (.05" - .7").
  • .4 inches  to 1" wide

Product properties:

  • For direct weather exposed joints
  • Weatherproof
  • Driving rain resistance up to 15.5 psf (ASTM E331/E547)
  • Air tight: <0.03 cfm/ft at 1.6 psf / <0.1 cfm/ft at 7.5 psf (ASTM E283)
  • High insulation properties: R-value for 2’’ wisw tape = 6.616 h*ft²*F/Btu; R-value 3’’ wide tape = 9.924 h*ft²*F/Btu
  • Passive House compliant
  • High sound insulation
  • Weather-independent installation
  • Moisture-adaptive membranes, which adapt their water vapor permeability to the humidity stress. An increased ambient air humidity causes the diffusion resistance to also increase
  • Extremely low emissions (VOC’s)
  • Tape impregnation won’t bleed and are compatible with most building materials
  • Halogen free - flame retardant for fire-safety
