Introducing the 316L Mi-FLEX 155mm x 40m COIL, a versatile and robust double-skinned flexible flue liner designed for relining masonry chimneys. Manufactured from premium 316L grade stainless steel, this flue liner is engineered with a smooth inner lining and a convoluted outer skin, both boasting a thickness of 0.105mm. Thanks to its innovative Omega-Lock seam, crafted from a single strip of steel bent at 180 degrees and folded in four planes, it ensures an exceptional, leak-proof seal.
HETAS and CE approved, this liner guarantees top safety and performance standards. Ideal for use with gas, oil, coal, coke, and cured dry logs or peat, this liner is your go-to choice for effective and efficient chimney relining. Installation is straightforward, with a clear step-by-step checklist included.
Remember, always sweep and inspect your chimney before installation. Once fitted, regular maintenance is as simple as an annual sweep, ensuring your chimney remains in optimal working condition.
