All About M-Flex Stainless Steel Chimney Liners 

If you have a chimney with an old or deteriorating chimney liner, or even with no liner at all, an M-Flex Stainless Steel Chimney Liner may be exactly what you need! Hailed as the original stainless steel chimney liner, M-Flex Stainless Steel liners offer some distinct advantages over other chimney liners. M-Flex liners are made from corrugated stainless steel that expands and contracts as your chimney heats and cools. This helps maintain the integrity of your lining system throughout the burn season.

M-Flex Stainless Steel liners are good for almost any type of fuel source. These sources include:

  • Wood
  • Coal
  • Oil
  • Gas
  • Corn
  • Pellets

M-Flex Stainless Steel Chimney Liners are made from .005” and .006” thick corrugated stainless steel. They are UL listed to UL 1777 standards and come with a lifetime warranty, so you know that you are getting a product that will last as long as your chimney.

Why Is A Chimney Liner Important?

Without a chimney liner your masonry chimney will begin to deteriorate in no time. Most building codes now require a functioning chimney liner, but that doesn’t mean that all chimney liners are created equal. Many older chimneys have a clay tile liner, which can easily become damaged. As your chimney heats and cools, the clay tiles can begin to crack, fracture, and even fall from your chimney’s walls, exposing the masonry underneath. Once this has happened, the integrity of your chimney liner has become compromised and your chimney’s health is put at great risk. It is critical that you have the right kind of chimney liner for your specific chimney and fireplace system. The knowledgeable professionals at London Chimney Services and Fireplace Shoppe can help point you in the right direction.

How Do I Know The Condition Of My Chimney Liner?

If you are having regular chimney sweeping and inspection services performed by a certified chimney sweep, they will be able to tell you the condition of your chimney liner. It is imperative that you have your chimney inspected by a                 CSIA-certified technician — doing so will ensure that you are getting the highest quality service from a knowledgeable professional who will steer you in the right direction. The professionals at London Chimney Services & Fireplace Shoppe can inspect your chimney and install the proper chimney liner to fit your needs.
