Fentrim

In new buildings air tight and driving rain proof joints in window installations are mandatory required by law. Blower door tests have shown that foaming alone is no long-term solution. Window installers mainly fall back on various pre-compressed tapes and foils to ensure permanent sealing. However, their practical application is often time-consuming and laborious.

One solution that has proven to be much faster and less complicated in application than conventional techniques comes from the Swiss manufacturer Siga in the form of Fentrim, the tape with full adhesive strength over its entire surface. With its green and yellow adhesive tapes Rissan and Sicrall the system manufacturer for materials around the air and wind tight building shell already enjoys the best reputation among craftsmen. Fentrim as well is aiming exactly at on-site requirements, but is in particular dedicated to the professional sealing of window joints. The adhesive tape is available in two versions: Fentrim 20 for internal airtight bonding (sd = 20 m) and as diffusion-enabled Fentrim 2 for creating the external driving rain proof and wind tight layer (sd = 2 m).
