Questions & Answers
Can it be used to wrap foil/fiberglass insulation around HVAC ducts
Hi there! Yes, Nashua 322 can be used to attach, seam, seal, and patch foil/fiberglass insulation around HVAC ducts. However, we recommend referring to code compliance to verify UL 181 requirements if necessary, for this application.
We had a mama racoon birth her babies in the space between our first floor ceiling and second the floor's flooring. These racoons damaged the HVAC intake duct in this space. Would this tape work to repair chew holes?
HI there! Yes, Nashua 322 Multi-Purpose Foil Tape may be suitable for patching or covering small chew holes in HVAC ductwork. The tape is specifically designed for sealing ductwork in HVAC systems and is commonly used for duct sealing, insulation patching, and seaming applications. It features a conformable aluminum foil backing and a high-tack adhesive that provides strong adhesion. For best results, the damaged area should be clean, dry, and free of loose material before applying the tape. However, if the raccoon damage is extensive or the duct has large tears, crushed sections, or structural damage, the affected section of ductwork may need to be repaired or replaced rather than simply patched. Best of luck!
Is this good for fusing fireworks tape
Hi there! Nashua 322 Multi-Purpose Foil Tape is designed and tested for HVAC applications such as sealing ductwork, insulation seaming, and patching. We do not test or recommend Nashua 322 for use in fireworks assembly, fuse securing, or other pyrotechnic applications. Best of luck!
Is the metal tape water-prof? Can silicone be applied to the surface underneath this tape and arouns the edge?
Hi there! Thank you for your question. Nashua 322 Multi-Purpose HVAC Foil Tape is designed for sealing ductwork in HVAC systems and features a conformable foil backing with strong adhesion. It is commonly used for duct sealing, insulation seaming, patching, and general HVAC maintenance applications. While the tape is often used in applications where an air-tight seal is needed, the available product documentation does not specifically state that it is waterproof, so we cannot make that claim. Regarding silicone, we do a significant amount of testing on product performance, adhesion, and HVAC applications; however, we do not specifically test Nashua 322 for compatibility with silicone sealants applied underneath the tape or around its edges. Because of that, we cannot confirm how the tape will perform in combination with silicone. We would recommend testing the combination in a small area first to ensure proper adhesion and performance for your application
Can you use the tape for interior duct work? Specially ceiling ducts, I want to use the tape inside the duck where it attaches to sheetrock. Does this tape have no or low VOC?
Hi there! Our 322 product will work for interior duct work and features low VOC content. We hope this helps!
Can this tape be used to seal small openings in sump pump cover to reduce radon levels?
This tape is not designed to stop radon. Mike
If I use this tape to secure mesh screens over metal heating vents, can it be removed at a later time if needed? If so, what is the best way to remove it?
Hi there! This product is meant to be a permanent foil tape, so while you can remove it, it will likely leave some residue behind. For the easiest removal, peel it back slowly, and in addition to a mild adhesive remover, to clean up any adhesive that may be left behind. Best of luck!
