  • Works great!
Size: 24''X25ft Thickness: 5mm
Easy to work with and insulates very well.

  • Very nice insulation and easy to work with
Size: 48''X50ft Thickness: 5mm
I needed to replace all of the duct insulation on a home I purchased due to rat damage that was found in the presale inspection. This is a great way to cover my ducts. I have installed it with two wraps of 1" strips to provide the needed air-space. Eacy to work with and much nicer than the itchy fiberglass alternative. ... show more

  • Worked well
Size: 24''X25ft Thickness: 5mm
I was able to nicely trim and tape to the 50 gal HW heater. A lot of$ for foam and thin aluminum foil though. (only reason for a 4*)

  • great for heat ducts
Size: 24''X50ft Thickness: 5mm
I have a very 100+ year old house. I was losing lots of heat in the ductwork that runs in the crawl space below the house. I wrapped some of the ducts with one layer of this as an experiment. Heat loss decreased by 20 degrees with only one layer of this insulation. It was very easy to measure, cut, and apply. I'm buying more for the rest of the ducts. ... show more

  • Saves me over 9 gallons of oil per month!!
Size: 48''X50ft Thickness: 5mm
I installed this in October and now it's February. have done some calculations, factoring in average temperature to calculate furnace efficiency year over year. My furnace efficiency has increased significantly since installing this, on average saving me about 9.75 gallons of oil per month. The last price I paid for oil was 4.40/gal so at that rate I'm saving about $43 a month. More if prices go back up. I got rebates for installing it, but even if I hadn't this would have paid for itself in about 3 months! Definitely recommend! It was easy to cut to size and wrap around my ducts, and then I secured it with the special tape for duct sealing (not duct tape - the shiny stuff). I didn't get quite enough for ALL my ducts so I definitely want to finish the job! ... show more
