Class A Factory-Built Chimneys:

Safety & Versatility

 

When your home lacks a traditional masonry chimney—or when installing a full brick-and-mortar structure isn't practical—a Class A factory-built chimney provides a modern, highly efficient solution.

 

Class A chimneys are double-wall or triple-wall insulated stainless steel venting systems designed to safely exhaust high-temperature combustion gases through roofs, attics, and exterior walls while maintaining safe clearances to surrounding combustibles.

 

When Is a Class A Chimney Needed?

 

Freestanding Wood Stoves: Required for venting high-heat, solid-fuel appliances when no masonry flue is available.

 

New Additions & Renovations: Perfect for adding a fireplace or wood stove to a room without an existing chimney stack.

 

Replacing Deteriorated Masonry Flues: Offers a clean, complete structural venting solution when rebuilding a brick chimney is cost-prohibitive.

 

Key Benefits of Class A Chimney Systems

 

UL 103 HT Certified: Tested and rated to withstand temperatures up to 2,100°F, ensuring maximum protection against potential chimney fires.

 

Superior Insulation: Dense ceramic or pack insulation between the stainless steel walls keeps internal gases hot—improving draft performance and drastically reducing creosote buildup.

 

Flexible Installation: Can be routed straight up through the roof or offset through an exterior wall, making them ideal for almost any home layout.

 

Long-Lasting Stainless Steel: Built with high-grade, corrosion-resistant stainless steel for maximum durability against harsh winter weather and moisture.
