Frequently Asked Questions

What exactly is the 150mm vitrified stopper used for?

This plug is used to hermetically seal unused chimney pipe outlets or sections, preventing unwanted drafts, dirt from entering, and external moisture, and ensuring the safety of the smoke evacuation system.

Is it compatible with any 150mm chimney pipe?

Yes, it is designed with standardized measurements to fit precisely into any metal or chimney flue with an inner or outer diameter of 150 mm, ensuring a firm hold and a proper seal.

Does it withstand weathering and the action of combustion acids?

Of course. Thanks to its vitrified outer layer, this stopper perfectly withstands exposure to the elements and resists the corrosive action of acidic condensates generated during combustion, significantly extending its useful life.

Are any special tools required for installation?

No complex tools are needed for installation. Its design allows for a direct and secure connection to the end of the chimney pipe, making assembly easier for both professionals and homeowners.
