DuraVent DuraTech LDC 18 to 24 inch Firestop Radiation Shield: closes ceiling openings for the four largest chimney sizes
The DuraVent DuraTech LDC 18 to 24 inch Firestop Radiation Shield is a plate that closes a ceiling or floor opening around the chimney. These four largest chimney sizes carry the standard grade, so they use this version rather than the high temperature shield. It goes above the level holding the anchor plate or ceiling support, not at the roof. It sits under the framing and adjusts to cover it, with its collar pointing up. 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.
Choose 18, 20, 22, or 24 inches to match your chimney. The 10 to 16 inch sizes carry the high temperature grade for factory built fireplaces, large masonry fireplaces, and boilers. The pipe comes in eight diameters, spaced 2 inches apart, and lengths of 6, 12, 18, 24, and 36 inches. The 18 to 24 inch pipe is made to order and cannot be returned. Passing through the roof?
