The 200 mm double-walled stainless steel rosette (Reference: B25142394) is an essential element for ensuring a clean, professional, and aesthetically pleasing finish in any flue system, pellet stove, or fireplace installation. Specifically designed to conceal the cuts in walls and ceilings where the flue pipe passes, this component perfectly combines technical functionality with high aesthetic standards, elegantly integrating into various interior design styles while ensuring the necessary airtightness and insulation in passageways.

Made from high-quality metal, this trim piece stands out for its excellent resistance to continuous high temperatures and corrosion caused by condensate and combustion gases. Its double-walled structure provides a superior thermal barrier, significantly increasing the overall safety of the heating system. Installation is quick and easy, fitting securely to the duct to prevent cold air leaks and providing a perfect perimeter seal that improves the room's energy efficiency.

Frequently Asked Questions about the Stainless Steel Rosette

What type of installations is this rosette recommended for?

This model is specifically designed for 200mm diameter flue gas evacuation ducts in pellet stoves, wood fireplaces and biomass boilers that use double-walled pipe systems.

How do I install it correctly on the wall or ceiling?

The rosette slides directly onto the exhaust pipe until it is flush with the wall or ceiling surface. Its design allows for a tight fit, although refractory mortar or high-temperature sealant can be used around the perimeter if a completely airtight seal is desired.

Does stainless steel change color with heat?

It is manufactured with specially treated stainless steel alloys to withstand very high operating temperatures without losing its mechanical properties or suffering premature oxidation or drastic changes in color.

Is it compatible with tubes from any manufacturer?

Yes, with a standard diameter of 200 mm for double-walled systems, it is universal and compatible with the vast majority of exhaust ducts available on the market.
