One of our HVAC lines was sweating when the A/C was running. I did some research and learned that this radiant/reflective insulation is ideal for insulating ducts and preventing the duct from contacting the humid air around it which causes condensation (or 'sweating'). I wrapped our ducts with this product, sealed the seams with tape, and there is no more sweating and I swear that the air coming out of our vents cooler too!
