DuraVent DuraTech LDC 10 to 16 inch Firestop Radiation Shield HT: closes ceiling openings above the chimney support
The DuraVent DuraTech LDC 10 to 16 inch Firestop Radiation Shield HT is a plate with an upward collar that closes ceiling or floor openings. It goes above the chimney’s support or anchor plate level, such as at an upper floor or attic entrance. It sits beneath the framing and adjusts to cover it. 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. This is the only permitted firestop for the high temperature 10 to 16 inch sizes used with factory built fireplaces, big masonry fireplaces, and boilers.
Choose a matching 10, 12, 14, or 16 inch diameter. The standard grade 18 to 24 inch chimney uses different firestop and roof shields. At the roof, use a roof shield instead. DuraVent recommends indoor runs because cold outdoor chimneys draw smoke less well and collect more creosote, a flammable buildup. Runs through rooms or closets need an enclosure preserving a 2 inch air gap. Entering the attic? See the DuraVent DuraTech LDC Attic Insulation Shield guard. The DuraVent DuraTech LDC 10 to 16 inch Firestop Radiation Shield HT ships free from My Cozy Outdoors with No Sales Tax (except WY) and the full manufacturer warranty.
