DuraVent DuraTech LDC Attic Insulation Shield: keeps loose insulation away from the chimney
The DuraVent DuraTech LDC Attic Insulation Shield is a collar that keeps loose insulation and debris away from the hot chimney pipe. It stands 15 inches tall in the attic. You need it wherever the chimney passes through an attic without being boxed in. It fits over a ceiling support box or a firestop radiation shield, the plate at the attic floor. Choose a diameter from 10 to 24 inches in 2 inch steps to match your chimney. DuraTech LDC is DuraVent’s large diameter chimney, an insulated double wall pipe made in 10 to 24 inch sizes for big fireplaces, furnaces, and boilers.
DuraVent recommends an indoor route when possible. A cold outdoor chimney draws smoke less well and produces more creosote, a flammable residue. Indoor runs through rooms or closets need an enclosure with a 2 inch air space around the pipe. A straight route draws best. One detour using two 15 or 30 degree elbows is allowed, with no steeper bends. The slanted section cannot exceed half the chimney’s length and needs an elbow strap for support. Need the plate underneath? See the DuraVent DuraTech LDC 10 to 16 inch Firestop Radiation Shield HT plate. The DuraVent DuraTech LDC Attic Insulation Shield ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
