DuraVent DuraTech Attic Insulation Shield: keeps attic insulation away from the chimney
The DuraVent DuraTech Attic Insulation Shield is a barrier that surrounds the chimney in your attic. It keeps loose insulation and debris from collecting against the hot pipe. You need it wherever the chimney passes through an attic without being boxed in. DuraTech is DuraVent’s double wall chimney, an insulated pipe with a 1 inch wall that takes over from the stovepipe at the ceiling or wall and runs up past the roof. A blanket of insulation separates its stainless steel inner wall from its galvalume or stainless steel outer wall. This keeps the outside cool and the inside hot to help smoke rise.
The shield has a base and a collar that wraps around the pipe. It stands about 15 inches tall and must remain above the insulation. It fits over a firestop radiation shield or ceiling support box. Skip it with 6 inch support boxes that include their own collar. Keep 2 inches of air between the chimney and anything that can burn. Choose 5, 6, 7, or 8 inches to match your chimney diameter.

The DuraVent DuraTech Attic Insulation Shield ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
