Technical Data

    Helix Premium Chimney Flue liner / Flexible Flue Liner 316L

    Helix Premium Flue Liner is the best liner on the market today, tested in a UK test lab to higher standards than any other liner available in the UK, is strong and flexible and represents a real leap forward in flue construction. Manufactured in the UK to exacting standards, it has been lab tested to pull nearly 100kg of weight and still pass a gas tightness test at 200 pascals of pressure - way above the standard required for chimney flue liner. Super flexible and super strong - we love this liner!

    Made from 316L grade stainless steel these liners have a spirally wound double skin construction that has a smooth inner flue way. These flexible liners are specifically designed for use with solid fuel. Double skin liners are not to be confused with single skin flexible liners which are designed solely for use with gas fires which must not be used with solid fuel appliances under any circumstances. A manufacturer's warranty is provided with this product for the lifetime of the appliance it is connected to, covering all solid fuels, approved compressed wood and paper briquettes, gas and oil. Sold by the metre - select the number of meters you need in the quantity drop down box above; it will arrive in one continuous length. Call us if you require more than 20 metres in length.
