A flue liner is not a product you want to fail within just a few years. Silvacore is manufactured by Duraflue and is designed for professional trade fitters desiring a premium product.

Silvacore "904" liner is 904 grade stainless steel internal, with an extra 316 external layer as additional protection against moisture


316 or 904 grade liner? 316 Silvacore has a 15 year guarantee and 904 Silvacore a 30 year guarantee. The difference is grade of stainless steel. If you are burning wood with occasional use of coal/smokeless fuel then fine. If you are a heavy user of coal/smokeless fuel then one would be advised to choose 904 grade.

As is the norm with chimney-liner manufacturers, chimney liner CANNOT be returned as this is a customised cut-to-length item direct from manufacturer on your behalf.

 Liner can be cut with a hacksaw. Silvacore can be fitted any way up in chimney.
