Several years ago I installed 2 hot air collectors, at ground level, and ducted the intake and return to my house. I unfortunately used interior flexible insulated duct work and now, after several years of UV, wind, rain, snow and hail the ducts are no good (duh).

I'm looking for exterior flexible duct work that I can use, hopefully insulated. I only need about 25 feet. I don't find much of anything on web searches accept for interior ducts and non-insulated ducts.

Any ideas?

Thanks,
Ross

Never seen flex duct for outside. Any animal can chew flex duct. Metal would be the best way.

Good thinking, and I don't want critters chewing their way into the house. I replaced them with 6" pipe.

Thanks,
