EconoHome Reflective Insulation Roll - 24in x 10ft, 3mm - Foam Insulation Core, Aluminum Heat Shield Sheet - Light Reflective Insulation Thermal Material for Weatherproofing, Condensation, Sound

If you need this kind of insulation this is great....

I bought this to insulate my windows at my small business. The old windows were so drafty I needed a cost effective solution. I saw a few videos of people using something like this for the same reason. I taped two Broom handles I bought from the dollar tree on each side. I can roll it up when I'm not using it. The windows are higher up so the Broom handles make it easy to just slide it up into place. With the Broom handles it helps to keep its shape keeping it securely in place in the windowsill. Keeps the cold out and my heat in.

I cut a piece to fit in my sunroof for the AZ summer. It makes a big difference.It’s over 100 degrees and very sunny right now and I feel minimal heat coming through my sunroof.It is stiff enough that when I tuck it in the edges it stays put and doesn’t push down on the mesh screen that rolls closedI’m going to cut a few pieces for the odd shaped windows in my fiat*tip. If you do this, be careful opening your mesh cover screen. Be sure the reflective sheet doesn’t get caught and roll up into the mechanism.

Easy to use. Just stiff enough to stay in place while applying. Easy to cut to shape.

i bought this to help with summer heat in my travel trailer. i placed it over the top of the trailer under a heavy tarp. it has made over a twenty five degree heat difference during the day. my air conditionier is not working half as hard. this is important being off grid. i tested this product and i found it to take all kinds of punishment. i place a peace of this on a Colman camp stove and at peak heat i could still place my hand on top of it after three minutes. it took all the punishment i could give it and i will be reordering it.

It is lightweight and easy place over my window to help keep the sunlight/heat out. Doesn’t take as long to cool the room during these intense high temperatures.

I bought this insulation to make side window sun shields for my car while it sit in the hat parking lot at work along with the windshield sun shield a already had. They dramatically reduce the heat in my car when I get in to it after work... and saves your interior from being cooked from the sun day after day this will pay off years down the line.

It's thinner than i thought it would be but it was super easy to install and the insulation seems to be working well. I would buy again.
