When the quality of your work relies on your ability to produce an airtight bond on joints and seams, you need products that meet your tough standards. Whether you’re working in vast temperature ranges, need a maximum-strength solution, or a tape built for aesthetics and performance, you can count on Shurtape to be reliable, roll after roll.
Let’s get started:
What Makes a Tape Code Compliant?
In some HVAC applications, UL listings are critical for code compliance. This means the HVAC tape used has the proper adhesion and exceptional shear strength needed to stay in place effectively for the life of the HVAC system.
HVAC tape can easily be identified by the UL Mark. You can check for UL listings in two ways: if the tape is unopened, you can check the packaging, but if it’s opened you can usually find it on the film or core label.
UL 181A-P
UL 181A-P is the standard for HVAC tapes used to seam, seal and join rigid ductwork (or duct board).
This listing has more stringent testing requirements that must be passed in order to be approved and must be made of either aluminum or aluminum alloy foil with a minimum width of 2.5 inches. These tapes must also be constructed with a release liner.
UL 181B-FX
UL 181B-FX is the standard for HVAC tapes used to seam, seal and join Class 1 Flex Duct.
Products meeting this listing are required to meet a minimum width of 1.825 inches, and can be made from a variety of materials such as foil, film or cloth.
