i have been usin partially clear, silvered Mylar like tape. It seems
to stick a lot better than aluminum tape. Practically as sticky as
Tyvec tape. I guess it should last a pretty long time. Any other
I have started wrapping remaining asbestos tape with it to seal it.
The asbestos tape is fairly secure anyway.??
What does your local building inspector say about it? If it complies with
your local codes, then go with it. You should know however that there are
reasons that aluminium tape is used... check the fire rating.
It's class 1 rating. I would have to check codes. Since is a great
product I have many uses other than vents.
When I moved in the house the vents would blow at least 140 degrees.
Probably hotter before I uncovered return vents and increased fan
speed. Now it's a new heater. The old oil burner was about 50 years
The tape is probably not for outside use, but I have a piece holding
ny cars win deflector intact.
True, its better than duct tape and more astetic too. My favorite is
that stuff that has a thick rubbery backing and shiny aluminum top
surface . Works well on sealing seams on ductwork and other
uses...even sticks to dirt.
