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.


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.

Silvacore Flue Liner

I purchased the 5" silvacor 304 / 316 flue liner from stove fitters warehouse. The item was swiftly despatched and there was very good communication from the sales team, On inspection of the flue liner, you could tell the difference comparing it to the more cheaper versions. The flue liner is made up of a twin wall using 304 & 316 stainless steel. The internal part of the liner is super smooth. I recommend to anyone thinking of purchasing a twin wall flue liner to purchase this one as you will not be disappointed.

Aga Wren

Really happy with our new Aga stove, looks great and burns very well with good air control. Good size fire box too so you can fit in plenty of wood. Now just looking forward to winter! Good service from Stove Fitter's, the online installation guide came in very handy. 5 stars.

Excellent service again and fantastic information source

Once again the stovefitters have been superb and guided me though selecting and buying the correct flue for my log burner (DG Ivar 5).

Will keep recommending to friends and family as now they want log burners now they have seen mine!

Keep up the great service guys!
