Adobe Acrobat Document Press Release

M&G DuraVent now offers a solution for positive pressure chimney: DuraStack, a modular double-wall positive pressure chimney system. Fully tested and listed to UL 103, UL1978, ULC/ORD C959, and ULC S604, DuraStack offers versatility for a variety of applications including boiler breeching, engine exhaust, chimney stack, and grease duct (model DIS only).

The DuraStack DIS and DAS venting systems are cylindrical, prefabricated, modular venting systems incorporating a unique extended inner flange designed for quick assembly and pressure sealing capability. DuraStack DIS and DAS is composed of a thick-gauge material for the inner pipe and coupling, providing a strong and rigid assembly; a self-centering flue design that significantly simplifies and accelerates the installation process; and a coupling configuration (patent pending), requiring only one locking band and the use of a regular, less expensive, high-temperature silicone sealant.

Available in sizes from 5" to 36" diameters, the DIS line offers double-wall, 2" insulated chimneys and the DAS offers a 2" air insulated product. For premium corrosion resistance and durability, the inner wall is constructed from .035” Stainless Steel 304 or 316. This is coupled with a .018” Stainless Steel 304, 316 or Galvalume® (Aluminum-zinc coated) steel outer wall. The DIS is lined with the highest-quality insulation, densely packed to ensure low heat loss, maximum draft and a 1” clearance to combustible materials.
