In order to be prepared against escaping heat and moisture, ducts, including wall sleeves, should be securely sealed. There are various possibilities to do this.

Which sealing solution is most suitable depends on the pipe being used and must be decided on a case-by-case basis.

For example, sealing solutions for double-walled stainless steel chimneys usually have a Tyvek adhesive edge. For concentric or plastic systems, the plasterable non-woven butyl adhesive edge is recommended. A flexible grommet with a long sealing neck ensures a secure seal and optimum humidity.
