Ductwork insulation

Ductwork insulation

Ductwork insulation

(OP)
I came across ductwork insulation a few years ago that was glued to the duct (I think) and was foil faced but was made of a armaflex type material. It was very durable. Does anybody know what type this might have been? Im using ordinary rockwool foil faced insulation in a traficable ceiling space and it is in tatters....

RE: Ductwork insulation

Closed cell neoprene insulation comes (also)with foil on one side but the thickness of the insulation increases, for same duct and ambient conditions, if you go with a foil faced one. They say, this is to avoid condensation on foil face. I had been speaking to Armaflex to give some calculation back up for one year and I just got one. I didn't yet check it.

PS: This is something to do with emissivity of aluminium.

RE: Ductwork insulation

BTW, are you speaking about closed cell phenolic panel ducting? The material itself is ducting and insulation.

RE: Ductwork insulation

Also known as pre-insulated ducting.  Saves lot of installation time, is very light as compared to conventional GI ducting + insulation.  

These come in panels and are to be formed into ducts using  manuacturer-supplied tools and tackles.  PAL, Italy are the pioneers in this field.  Maybe there are others too.
