    So far, so good
    We have a climate controlled garage with a bonus room and bedroom above it. The rooms above it were always hot in the summer and freezing in the winter. A few months ago, I checked out the attic around the bedroom and saw that the only insulation was r12 on the kneewalls. So we decided to put up some radiant barrier and then add unfaced r30 to the floor. Since it was January, it started out really cold in the attic, and as we got the Reflectix installed, the attic temperature became much more comfortable. That bedroom temperature has been much more consistent and warm since installing. We cant wait to finish the rest of the attic.

      I purchased this rolled Insulation as an idea and an attempt to lower the unbearable garage temperatures this past summer. Our garage door faces West and would absorb the extreme afternoon temps daily with indoor garage temperatures reaching 104 degrees. The outdoor surface temperature of the garage door would read 130 degrees during the scorching summer months. Due to these extreme temperatures, I was also concerned with the best method to adhere the insulation to the interior panels of the door that would hold up and not peel off. I researched and decided on using Roberts Max Grip Double-sided Permanent Carpet Tape found in the flooring section at Home Depot. It took my wife and I approximately 2 hrs to install on our 2 car garage. The difference inside the garage has been staggering and now have a comfortable temperature range we can live with. The infrared reader was measuring 130 on the exterior door and approx. 84 on the interior this past summer so the average temperature change has been -22-25 degrees. It holding up great after the first summer.

        Easy to install
        I still have to see how well this helps my garage in the winter but installation was easy. I have a single, two car garage door. I measured and cut each panel, then used Loctite PL375 to glue it to the sections. I didn't have to make any adjustments to the garage door opener and I have a good amount of the insulation left over for something else. I may consider adding another layer or using it in the attic. My garage is part of the house but not heated. I'm hoping to at least keep it above freezing this January. The bedrooms above the garage get pretty cold, especially the floors. The finished look is definitely better than the plain steel panels. I think it's quieter in there too, I don't hear the cars passing by any more.

        Pole barn insulation
        Product arrived in a very timely manner. Very easy to work with. Only needed a few basic tools to install. We used a utility knife, straight edge, and a stapler with 1/2 inch staples.

        So easy to work with.
        I installed this product all by myself on the inside of my garage doors. It took me about 2 hours to measure, cut the pieces and install in the doors. Really looking forward to seeing how well it helps reduce the very hot AZ temps in my garage and by extension the inside of my house in the next couple of months. It was totally painless to install. :)

        We installed this in the attic. It really works.
        I saw this in an attic before and wanted to install it in ours. We installed the Reflectix insulation and the attic became cooler as we progressed. It cost us an eighth ofwwhat Costco wants. All the tools we needed are a T-50 staple gun, a utility knife and a pair of large scissors. I strongly suggest buying several boxes of staples. It took us four hours with doing planning the day before. Leave a gap on either side of the roof peak vent. We used a 2 foot by 6 foot piece of 3/4 inch OSB to stand on ( one for each of us) to save us from having to stand on the ceiling joists. Our AC Guy saw it when we finished and said it will take a load off of the attic-mounted air handler. We also put in a deck in the attic to store our Christmas decorations (we have a lot) and a few other items. I went up there today when it was over 80 outside. It was the same in the attic as outside: just over 80. Saving on AC this summer and getting rid of storage will make this break even before Christmas. Oh yes....this is not a beginners project as no instructions are given. Look at the Reflectix online brochure. Study it. This is a special order item. Get it delivered to your home.

        Works really well on garage door!
        I installed the Reflectix radiant barrier foil on the inside panels of a double and a single garage door. I installed these by using not only double-sided tape but also by securing the foil sheets with the existing door panel hinges. The installation worked out really well. Now, when the outside of the garage doors measures a hot 102 deg F on a sunny day, the inside of the same doors stays at about 70 deg F. Wow! What a difference it makes. Now it is almost the end of October in Austin, TX, and outside it is quite a bit cooler than what we see in summer. I am waiting to measure the temperature differential on a hot summer day. Home Depot did an excellent job in shipping the foil quickly and also charging for it very reasonably.
