DuPont™ Insta Stik™ Flex+ 

Insta Stik™ Flex+ is a moisture-curing, fire rated, one-component polyurethane foam sealant. It is mainly used for sustainable airtight installation of windows and doors. Due to its impressive flexibility, it copes with window frame movements caused by temperature changes and wind loads without degradation of the airtightness. In addition, the foam sealant shows good acoustic and thermal insulation performance. 

Insta Stik™ Flex+ has been tested according to ÖNORM B 5320 “installation of windows and doors into walls”.

In combination with DuPont™ Tyvek® tapes, Insta Stik™ Flex+ passed the system test performed on a real building element. When using the airtight Insta Stik™ Flex+ foam sealant to fill the building joint, there is no need to apply an interior airtight tape.
