500 sqft (4ft x 125ft) of NASA TECH Commercial Grade Perforated No Tear Green Energy Radiant Barrier Reflective Insulation Attic Foil Roof Attic House Wrap SCIF RIFD

The material is thin but durable, not anything like aluminum foil that can be torn and punctured. It's highly reflective and the price was better than anywhere else. Inside the box the owner leaves his contract information for problems or questions.Very happy with the purchase.

Great energy saving underlayment. In addition adds a bit of R-value as well. Easy to apply and works.

This foil is almost tear proof but cuts easily with a knife. The great thing is that it reflects heat rather than insulates. We used to "insulate" our entire house and attic during a to the studs remodel in 2018 . Our gas bill dropped 30% compared to the old fiberglass insulation. This time I used to insulate plumbing and heat ducts under a mobile home in central Montana.

Great product. Robust but easy to cut with scissors blocks heat transfer through roof for a few hours which is all you need sometimes.

Quality is good but had to return due to wrong measurements.Still waiting on the refund. Last time I checked it was going to be issued 12/8/23. It’s not 12/9.An update would be great.

Really holds up

I love how it does what it's supposed to do, it eliminates the heat in my storage easy to cut in size and very strong.

I used this to wrap my flexible ducts in my attic. The ducts were fine but the plastic wrapping around the insulation had deteriorated and was falling apart. I wrapped the foil around the outside of the insulation to hold it all together. The foil was very thick and does not hold its shape like cooking foil thickness. I cut the length long enough to wrap around the duct and put it on four feet at a time. Any longer and it would have been unmanageable. I used aluminum tape to hold it in place then use Dap silicone to "glue" the edges down. It worked great. I just went back in the attic after a month and it is holding tight. I only needed half a roll to do a lot of ducts.
