DD24125 Air Double Reflective Polyethylene Insulation Roll, 2-Feet by 125-Feet

This exceeded my expectations. I used it to cover the ceiling of my garage and it made an incredible difference.On a hot day I measured the ceiling temperature to be 106 degrees Farenheit (41 Celsius) without Reach Barrier and 86f (30c) with Reach Barrier. I was not expecting such a dramatic change. The average daytime garage air temperature itself is now about 10f cooler (5c) and my air conditioner is far more effective. I'm very happy.The installation itself was pretty simple. I covered a little over 500 square feet (50 square meters) by myself in about 4 hours. If I had someone to hand me tools, move ladders, reload staplers, cut tape, etc. I could have finished in half the time. I had no problems at all. It's very light weight and easy to move, but stiff enough to hold itself in place once wedged between the ceiling joists. Stapling it to the ceiling was quick and easy with a hammer tracker.I will update my review once I asses winter temperatures.

We used this to insulate the upstairs of our cabin. It is a sleeping loft and we have a limited amount of head room, so we needed thin. It worked great! We have a ridge vent, but no soffit vents, so we were nervous on what to use. After a lot of research we decided this would allow the appropriate breathing and moisture control while still insulating. It has been great! We kept a gap downstairs to allow air flow behind the insulation so we don't get condensation. The humidity does get a little high in the loft with the insulation, but vents easily and hold the heat/cool wonderfully. We're very happy with the product. It was very easily to install, feels very durable, and is working perfectly.

Great product I bought this to underline my camper for the winter to keep the warm in and the cold out we stapled it down and as soon as it was on I could feel a difference in the flooring I also had extra so I put it on my windows and 5 min later checked my thermometer and it had warmed 6°f inside very satisfied

This stuff really works. Made a hude difference in my metal-roofed shop. Make sure you have an air gap, otherwise it will conduct the heat, not reflect radiant heat. Also seal it up well. It will make a tremendous difference.

great product, i have not finisshed my project but i have done some testing and the difference with and with out is 26 degrees.

Amazing stuff.... keeps my house cool in the summer and warm in the Winter

We got this to line the inside of our garage door. It faces south and gets really hot in the Summer. It seems to be helping a lot. We have hit 105 so far and it has kept the garage from getting super hot.

GREAT VALUE FOR THE PRICE
