Double Bubble Reflective Foil Insulation: (4 X 50 Ft Roll) Industrial Strength, Commercial Grade, No Tear, Radiant Barrier Wrap for Weatherproofing Attics, Windows, Garages, RV's, Ducts & More!

Received and 1 roll had damage, so sell said he would replace it.

I am using this bubble foil to insulate my polycarbonate greenhouse on three sides and the roof. I made shades that I can open to let in the sun during daylight hours. If it is cloudy, snowy and cold, I leave the shades down and the foil reflects the electrical lighting. I reside in Metro Chicago and this system reduces my energy costs.Time will tell how long this particular product holds up to the sun, cold and summer heat.

I used the insulation for my RV windows and found it very easy to cut and install. It has decreased our air-conditioning usage by about 10%. Worth every penny.

Not window shade stiff, Up-Date, I used "Heavy Duty Packing Tape" on the edges to give support so it is not as "Floppy", so I up graded to 4 stars.

Bought to put in our RV windows while it is not in use. Easy to cut and put in the windows.

It keeps the heat out in the summer and in the winter keeps the heat in.

This cuts easily but doesn't tear easily. Thick and rugged. I am using it in multiple applications and am happy with each one.

Easy to work with, durable and exactly what I needed to make covers for my camper.
