DuraVent DuraTech LDC 12" 0/12 - 6/12 Pitch Ventilated Flashing
The DuraVent DuraTech LDC 12" 0/12–6/12 Pitch Ventilated Flashing is a premium chimney roof penetration and weatherproofing solution designed for the DuraTech LDC all-fuel double-wall chimney system. Ideal for factory-built fireplaces, large masonry fireplaces, and vented non-condensing appliances, this ventilated flashing ensures a secure, watertight seal where chimney pipes pass through roofs with low to moderate pitch. It enhances chimney system protection, leak prevention, and long-term installation durability in residential and commercial applications.
Engineered for UL 103 Type HT listed chimney systems, it supports 10" to 16" diameters and features a solid-pack design with 1" ceramic insulation between a stainless steel inner wall and stainless or Galvalume outer jacket. It maintains a 2-inch clearance to combustibles and is tested to US and Canadian standards, delivering reliable high-temperature performance, roof flashing efficiency, and weather-resistant chimney venting safety.
