Hannoband®-3E is a pre-compressed, self-expanding multi-functional joint sealing tape based on polyurethane soft foam with patented functional membranes. It is impregnated with an acrylate dispersion impregnation, accessory agents and filling agents. Hannoband®-3E is ideal for fast, easy and durable window and door installations meeting all of the requirements pertaining to an air tight and heavy rain tight sealing.
 
Three sizes are available:

• Expanding foam tape for gaps between 4 to 9mm (3/32" - 3/8")  2-1/2 inches wide x 30'-10" foot long roll
• Expanding foam tape for gaps between 6 to 15mm (1/4" - 5/8")  2-1/2 inches wide x 23 foot long roll
• Expanding foam tape for gaps between 10 to 20mm (3/8" - 3/4")  2-1/2 inches wide x 15'-5" foot long roll

Product properties:

• 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’’ wide 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
