Typical Use & Summary:

  • Options available for use with our Stainless Steel Flexible Chimney Liner Kits or Stainless Steel Rigid Chimney Liners
  • Chimney liner insulation kits help ensure safety and efficiency for stainless steel chimney liners

Why Insulate?

An insulated chimney liner has a better draft and stays cleaner longer, which is a benefit to any stainless steel chimney liner.
