Particularly suitable for the perimeter sealing of windows and doors.


A special multi-functional all-in-one PUR foam joint sealing tape with outstanding properties. Having an a-value of 0.00 m³/ [h.m.(daPa)n], the pre-compressed tape is 100% airtight at the internal seal area, contributing in minimizing heat loss by convection. It also possesses an optimal vapour diffusion gradient from the inside outwards (50:1), enhancing the external transmission of moisture, enabling the joints to dry out quicker.


Particularly suitable for the perimeter sealing of windows and doors.
