Wall pass-through trim rosette Poujoulat for flue pipe DN80, white

Designed for neat and secure wall entries, the Poujoulat wall pass-through trim rosette for flue pipe DN80 in white covers and seals the gap where a DN80 flue or exhaust pipe passes through a wall. The circular shape and smooth white finish create a discreet transition between the pipe and the wall surface, preventing visible gaps, reducing drafts and limiting ingress of dust or small debris. This rosette is intended for residential and light-commercial chimney and ventilation installations where a finished wall penetration is required for a flue with nominal diameter DN80.

Advantages

The rosette provides a tidy visual finish while offering basic protection against drafts and debris at the wall penetration. Its purpose-built size for DN80 flue pipes ensures a close fit around the pipe, simplifying installation and helping to maintain the integrity of the wall opening. The white finish matches common interior and exterior surfaces and is easy to paint or clean if needed. Constructed to meet the practical needs of chimney and ventilation routes, the component reduces the need for additional trimming materials around the pipe entry.

Suitable for

• Residential chimney or flue installations with DN80 pipe diameter
• Light-commercial ventilation and exhaust duct wall penetrations
• Areas where a neat, finished wall entry for a flue is required

Key specifications

• Nominal flue diameter compatibility: DN80
• Shape: circular rosette designed to encircle the pipe
• Finish: white
• Function: covers and seals wall penetration around flue or exhaust pipe
• Application: suitable for interior and sheltered exterior wall entries in residential and light-commercial settings

How to use

Place the rosette around the DN80 flue or exhaust pipe at the point where it passes through the wall, ensuring the pipe is centralized within the circular opening. Slide the rosette against the wall surface so it covers the gap completely; if the design includes a split or two-piece option, align and secure both halves around the pipe according to the manufacturer's assembly method. Use appropriate sealant or caulking around the inner and outer edges if an air- or weather-tight seal is required, taking care to select a sealant compatible with the wall material and the flue operating conditions.

Usage recommendations

Check compatibility with the specific DN80 flue system and local building codes before installation. For exterior exposures or high-temperature exhausts, use suitable high-temperature sealants and verify that the rosette materials meet the installation environment requirements. If uncertain about clearance, firestopping, or insulation needs at the penetration point, consult a qualified installer or building inspector.
