Flexible Air Ducts?

A quick search turned up these as possible options. Check the MSDS and manufature literature for more information. RHP- Ember Glow Glue Fireproof glue for apply Ember Glow to gas logs. Model #GL-1 Or 3M™ Scotch-Grip™ Rubber Based Adhesive EC-4419 Fire-resistant, synthetic, rubber-based adhesive. Used for bonding gaskets in aircraft interiors and for attachment of de-icing boots. Quick dry time. Can be applied by brush or flow gun. Controlled flow. Even spreadability when brushed applied.

Thanks very much for reply, I'll see if it is working for me!

You have not specified what material is the flexible ducting you are considering. Flexible ducting are made from metal, plastics and composite materials. Therefore different methods of manufacture and 'glueing' together are employed.

Thanks for replying, I am considering only making them from "plastic", which means Metalized polyester film, HDPE barrier, and PET, and I am also considering composed material but also of plastic type(this type is moisture barier to go under laminated floor or other kinds of foam not thicker than 2.5 mm).

You may consider heat seal joining method which is employed in HDPE.

Thanks can you tell me more about how this is done?

Thanks I 'll what can it do for my problem.

I'd be real careful there.

Metal thickness is a factor in fireproofing standards.

Ask your local inspector for a review before you go too far.

Thanks for comment, but one of the main reason to ask this is because lack of help in this area, usually it is produced with steel wire, if you have info where to look for this(because local officers don't know anything about it except that somewhere there is a standard!)(important note: from my country it is impossible to pay over net for standards books)
