Repair to HVAC flex duct covering - need advice
The gray plastic covering on my home's HVAC flex ducting is beginning to crack. I don't think there is too much air loss, but I'd like to fix it before it gets worse. Rather than replace all the ducting (expensive), is there a way to 're-wrap' the ducting? For example, I was thinking that Tyvek could be used. Are there any other wrapping materials out there that can help keep the cost down without replacing all the ducting?
