The Evolution of Dryer Venting
In the past 4 decades, the most common practice for venting clothes dryers was the use of vinyl ducting. Over the years, through new technologies there have been many different products developed for venting dryers. With the introduction of aluminum foil, dryer venting manufacturers were able to make significant progress towards heat and flame resistance. The most commonly used aluminum foil product was designed with a polyester lined core.
In this past decade, there has been a major breakthrough in flexible duct pertaining to dryer venting specifically. Underwriters Laboratories (UL) developed a standard called Clothes Dryer Transition Duct – 2158A. It revolutionized the dryer venting industry. For the first time, a flexible duct was approved for both gas and electric dryers. Rigid pipe and semi-rigid ducts have been endorsed by dryer manufacturers from the beginning. Standard 2158A opened up new opportunities for flexible duct which is much more consumer friendly.
UL Approved Clothes Dryer Transition Duct was developed to protect consumers from the potential hazard of DRYER FIRES. This is becoming an increasingly serious problem due to the use of non UL APPROVED DRYER VENTING PRODUCTS. Vinyl duct is NOT recommended for clothes dryer venting.
If you are not prepared to use aluminum rigid pipe, the only product safe enough to use to vent dryers is a fully UL Approved Clothes Dryer Transition Duct. Like the Dundas Jafine ProFlex™ duct.
