SEALTECH 3mm Reflective Insulation Roll - Premium Foam Core Radiant Barrier for Energy Conservation -Commercial Grade Soundproofing Thermal Shield for Indoor and Outdoor Use (8" X 10')

2 car garage and 100 feet was more than enough. Plan to double layer it in each garage door slot and will definately have enough material to do it. 1 Layer is great! muffles sound- makes a difference in the temperature here in the hot florida sun. The main issue is the edges and side rails that this goes into. I saw others on these pages suggest using that spray foam to fully seal but I got a 1" foam pipe insulation, cut it in half and was able to cram it in there without it looking bad at all. This was in my opinion a superior looking and less weighty solution to the inevitable gaps you'll come upon when installing

I'll give it a 4.7 totally Love the ease of installation wished I could of had this lovely item in a thicker sheet though definitely seen the difference from having no insulation in my storage barn I only did the ceiling but if this was made at least 3” thick I'd purchase and install inside the walls too between studs love this item thank you . The 4.7 only because they couldn't keep up with same size inventory and my last roll I was forced to buy a larger size width wide because sold out the size I needed it for had to measure cross cut sections to fit as same size needed and bought previously.

real heavy duty and great quality. i little expansive. but it will help reduce the ac cost in my RV. I highly recommend this product!

Haven't actually used it yet, but this is clearly a strong and well-made product and a definite step up from the air bubble type that is cheaper and similar in application but is neither as solid or as highly rated for sound or RV factor.

Very fast delivery and the right stuff and great price

Used to double down on two feral cat houses...Thank you Walmart

It's what i wanted but didn't get it after a week later than the date said. they let me know on the date of arrival that it was going to be late. i could have been happy if they would have given me a discount but nothing

It is very thin and flimsy, wish I would have gotten the 10mm. I live in a mobile home with double pane windows, so I wanted it to put in between the two windows instead of trying to figure out how to attach to inside. I thought I could just cut to size and slide it up between the double panes, but so flimsy, had to get foam board and cut to size to keep in place. Then I used two pool noodles, one on each side to secure it in between the windows, one on each end of the thermal insulation. Those fit the width between the windows perfect. And holds it in place

great product. took forever to get delivered though

This product is fine, it was the wrong product for me. It came all folded over and I wanted to use it for skirting…. It had a lot of folds and didn't want to lay flat.
