joint sealing tape is a soft and flexible expanding foam used predominately as a weather-seal to prevent water ingress and retain heat in external and internal applications. Along with its excellent acoustic properties, under high compression it will create an industry standard 600 Pascal- rated weather proof seal. In low compression applications, it makes for a draught proof, aesthetically pleasing join between smooth or irregular surfaces such as brickwork, concrete, wood and plastics etc. The foam is an open cell polyurethane, heavily impregnated with acrylic based UV and water-repellent resins that also have flame retardant properties. It is supplied in pre-compressed, slow expansion rolls with a self-adhesive scrim tape applied to one side to aid application. When unrolled and applied to a window frame or similar structure, the decompression process allows for enough time to position and install the frame whilst the foam tape expands and embeds itself to the adjacent surface after the installation has been completed. Pascal Rated to 7mm wide, which is the air tight, protection against driving rain 700pa, noise insulation etc. But can expand up to 17mm full if allowed but over 7mm it will only perform as a gap filler.
