Love this, looks way better than the foil stuff surely would. Was very easy to install.

US Energy NASATECH (Pre-Cut for 16 Panel) 2 Car…
  • This is the upgraded 5/16 Foam Core with Super Duty Double Sided Foam Tape Two Car Garage Door kit that Creates an air pocket to obtain an R8 value insulation!!!
  • Light Weight and Easy to install (no impact on garage door performance)
  • Saves heating/cooling costs: (keeps the heat i during winter, keeps the heat out in the summer)

The US Energy Insulation kit is good at reducing the electricity bill. Straightforward installation and was able to do the job solo, but waiting to see how the adhesive holds.

The instructions do state that you need to give the tape more time in temps below 70F, which it is, but I felt like the ends kept wanting to come up. Hopefully, it will hold, but if I have to go back with additional adhesive in a few spots later on I won’t be surprised or upset as long as it’s not a widespread issue.

I have a side entry door that has some pretty large gaps that I still need to address before I feel like I can give a truly fair assessment of how well it holds in heat during winter and cool air in the summer. I’m more concerned with performance in the summer since we get some pretty consistent high temps.

I installed this product over a 3-day period. On the first day, I thoroughly cleaned the garage door with water and a Simple Green degreaser allowing it to dry overnight. I had to remove the hurricane braces which was a pain but manageable with only 1 person.

The tape went up the 2nd day and was allowed to dry overnight. I had some tape left over – If I could do it again, I would have used two strips for the vertical pillars. I cantered the tape where I could have put 2 strips vertically. Seems plenty strong as is especially with the hurricane bracing holding it up.

I have a south facing garage and this insulation really makes a big difference. It’s still warm in the summer, but you don’t get that sizzling hot radiant heat from the doors. It’s great. Totally worth it.

How to install a Garage door insulation kit?

The installation of a garage door is not so tough job. It might be hard for one person but can be done by two persons effortlessly. above we showed you some best garage door insulation kits to keep your garage air-conditioned. After the purchase and delivery. Follow these simple steps to DIY your insulation foam:

  1. In the kit, you’ll find long pieces of bubble foil(white or reflective).
  2. You get a huge roll of double-sided tape, a squeegee, and a razor blade.
  3. Put the tape up to the day before, it makes it tacky as it sits. Cover the entire length of the garage door first.
  4. Expose the 2nd side of the tape and let it sit for 12 – 24 for best adhesion.
  5. Separate the foul rolls, and then roll up a single 18′ length by itself. this makes it SUPER easy to install.
  6. One edge of the roll is machine-cut straight as an arrow. Find that side and put that at your joint as it will give you the cleanest look. (Do this on every roll, one side is wavy other is straight).
  7. Place the roll against the tape and slowly unroll it right into the door. Press it in place as you move along.
  8. Make some relief cuts around the hinges (some remove the hinges, but I didn’t) and keep unrolling. Cut off the excess at the end and also at the widths side.
  9. Then trim around the hinges. The more time you take, the cleaner the installation.
    Note: The tape goes on the horizontal ribs of the door, not on the flat panel itself. That would defeat the insulation properties.
