904 316 Chimney Flue Liner 5" 6" SILVACORE


"SILVACORE liner is what I would fit (and have fitted) in my own chimney. Do it once, do it good." Julian Patrick, author of The Stove Fitter's Manual.

Designation: EN1856-2T600N1DV2L50008G


904-grade Silvacore has a 30-year guarantee. 316-grade has a 15-year guarantee. A flue liner is not a product you want to fail within just a few years. Silvacore is designed for professional trade-fitters desiring a premium product for chimney lining. 904 Silvacore has a 30-year guarantee against failure via corrosion. 316 Silvacore has a 15-year guarantee against failure via corrosion.

Silvacore is created from two compressed stainless steel layers and this unique laminate stays smooth when the product is passed around chimney bends (with lesser quality liner the laminate usually comes apart allowing acids from soot deposits to enter and cause corrosion).

904 and 316 are grades of stainless steel. 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.

Slumbering a stove or "banking it up" overnight can shorten the life of liner. This is because the bad stuff in the gases is not burned off and condenses within the liner. Slumbering is bad for liner, cowl and the environment. Don't do it. Do not mix wood with coal or smokeless fuel (moisture in wood reacts and creates Sulphuric acid). Silvacore 904 should last 30+ years and I recommend it above all others. Julian Patrick. Author Stove Fitter's Manual.

Most helpful people in the stove fitting world!

Julian and Aaron were most patient with me and took the time to answer all the queries I raised, they even telephone missed calls back, wow, what service! I especially appreciated their help when I'd ordered an extra cowl for another chimney and discovered I'd asked for the wrong size.

Service and quality.
