    The ASHT+, with its double-wall all-stainless-steel chimney and exclusive Secure Plus insulation, minimizes heat loss through the chimney walls, and can withstand the intense heat. The free-floating inner lining is attached only to the male coupler at the top, expanding and contracting freely with temperature fluctuations. The external casing of the Secure Temp ASHT+ carries the structural load.

    The Secure Temp ASHT+ high-temperature chimney is certified by Intertek Testing (Warnock Hersey) to UL-103HT standards for all diameters of 5, 6, 7, 8 and 10 inches. Secure Temp ASHT+ has a temperature rating of 650°C (1200°F); max. continuous, 760°C (1400°F) brief forced fired; and 1150°C (2100°F) 3 x 30 minutes, tested.

Instrumental in the company’s growth has been an ongoing focus on product improvement and the introduction of innovative products. This drive for excellence has given rise to the Secure Temp ASHT+, one of the most popular lines of venting products in North America. This high-quality product ensures that end-users benefit
    from maximum safety and proven corrosion protection.

    The use of stainless steel, selected for its resistance to high temperatures and corrosion, lends outstanding durability to the Secure Temp ASHT+ high-temperature chimneys. All chimneys feature 1 inch of superior-quality, high-density Secura Plus insulation. This exclusive insulation keeps the temperature of the outer casing relatively low, keeping safety features as simple as possible.
