7 Inch DuraPlus Firestop Radiation Shield

A Duraplus chimney with a filter is fed through the ceiling to prevent the joist from overheating. The revolutionary triple-wall architecture is intended to keep the exterior temperature cool. It erects a fire-resistant framework to safeguard the building's chimney. This chimney component's aim is to improve security within the ventilation system.

• Use when air-cooled chimney is required
• Outer diameter is 4" larger than inner diameter
• Use in-ceiling/floor penetrations when a ceiling support is not used

• Fits on the underside of the ceiling and adjusts to cover framing. (See installation instructions for proper placement.)
• Free-floating inner 430-alloy liner maintains structural integrity in chimney fires
• For uses with wood stoves, fireplaces, furnaces, boilers, stoves, ranges, water heaters, or other appliances fueled by wood, oil, coal, or gas
