ISO-CONNECT DUPLEX can be used for airtight and driving rain-proof sealing of connection joints on windows, doors and panels. The extremely flexible and stretchable special film consists of an adaptable soft plastic fleece that is fully self-adhesive and can therefore be easily attached to the frame profile. ISO-CONNECT DUPLEX is used on both the inside and outside and, with its coordinated sd-value, ensures consistent drying in the joint. This keeps the construction joint dry and prevents unacceptable moisture accumulation.
