Manufactured from high-quality stainless steel, these liners are ideal for wood burning and multi fuel appliances installed within existing masonry chimneys.\u003c\/p\u003e\n\u003cp data-end=\"267\" data-start=\"0\"\u003eDura Flue is the only stainless steel flexible chimney liner in the UK that can be installed in either direction. Its patented manufacturing process creates a stronger, more durable liner that is highly resistant to corrosion compared to traditional flexible flues.\u003c\/p\u003e\n\u003cp data-end=\"331\" data-start=\"269\"\u003eDura Flue is made from two separate layers of stainless steel:\u003c\/p\u003e\n\u003cp data-end=\"730\" data-start=\"333\"\u003e\u003cstrong data-end=\"348\" data-start=\"333\"\u003eOuter Layer\u003c\/strong\u003e\u003cbr data-end=\"351\" data-start=\"348\"\u003eThe outer skin is formed from a pre-profiled stainless steel ribbon with deep, tightly spaced corrugations. This creates a tough protective shell that helps prevent damage during installation, especially when lowering the liner through rough brick chimneys. Unlike softer traditional liners, Dura Flue is far less likely to dent, crush, or become compromised before installation.\u003c\/p\u003e\n\u003cp data-end=\"1238\" data-start=\"732\"\u003e\u003cstrong data-end=\"747\" data-start=\"732\"\u003eInner Layer\u003c\/strong\u003e\u003cbr data-end=\"750\" data-start=\"747\"\u003eThe inner skin is manufactured from a separate smooth stainless steel ribbon, treated with a specialist oil spray during production to maintain a clean, undamaged surface. Unlike many traditional liners, the inner wall is not folded or scratched during manufacturing. Using a patented pressure-locking system, the inner and outer layers are secured together without damaging the steel. This creates a smooth, uninterrupted passage for flue gases and greatly reduces the risk of corrosion.\u003c\/p\u003e\n\u003cp data-is-only-node=\"\" data-is-last-node=\"\" data-end=\"1630\" data-start=\"1240\"\u003eDura Flue also features a smooth internal bore with no flaps, folds, or sharp lips inside the liner which is a unique feature in the UK chimney liner market. Traditional liners with internal seams and directional arrows can separate, snag, or deteriorate over time, particularly during installation. Dura Flue’s seamless internal design improves durability, reliability, and long-term performance.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eTwin skin stainless steel construction\u003c\/li\u003e\n\u003cli\u003eExcellent flexibility for easier installation\u003c\/li\u003e\n\u003cli\u003eSuitable for wood burning and multi fuel stoves\u003c\/li\u003e\n\u003cli\u003eCorrosion-resistant inner and outer layers\u003c\/li\u003e\n\u003cli\u003eDesigned for domestic chimney relining applications\u003c\/li\u003e\n\u003cli\u003e\n\u003cspan\u003eHETAS approved and CE marked\u003c\/span\u003e\u003cbr\u003e\n\u003c\/li\u003e\n\u003cli\u003e\u003cspan\u003eConstant burning temperature of T600 and maximum T1000\u003cbr\u003e\u003c\/span\u003e\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eSpecifications\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eStandard Length is 2m\u003c\/li\u003e\n\u003cli\u003eDiameter: 5\"\u003c\/li\u003e\n\u003cli\u003eFuel Compatibility: Wood Burning \/ Multi Fuel\u003c\/li\u003e\n\u003cli\u003eApplication: Flexible chimney liner\u003c\/li\u003e\n\u003cli\u003eInstallation Type: Existing masonry chimneys\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWarranty Options\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e316 Grade Stainless Steel – 15 Year Warranty\u003c\/li\u003e\n\u003cli\u003e904 Grade Stainless Steel – 30 Year Warranty\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eFurther Details\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eProfessional installation is recommended\u003c\/li\u003e\n\u003cli\u003ePlease ensure the correct liner size is selected for your appliance\u003c\/li\u003e\n\u003cli\u003eSuitable for use with solid fuel heating systems\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Dura Flue","offers":[{"title":"2 Metres - 316 Grade - 15 Year Warranty","offer_id":61880857559370,"sku":"DF-5-316","price":39.99,"currency_code":"GBP","in_stock":true},{"title":"2 Metres - 904 Grade - 30 Year Warranty","offer_id":61880857592138,"sku":"DF-5-904","price":79.99,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1017\/1344\/5194\/files\/DFLiner1200x1200_3bae61af-e675-4457-ac40-36a5d6b5bd74.png?v=1779451082","url":"https:\/\/beechandmaple.co.uk\/products\/dura-flue-5-flexible-chimney-liner","provider":"beech\u0026maple","version":"1.0","type":"link"}
