    Can I run the foil across the door leaving a gap instead of sticking to the panel as you show? Would my way not create a higher R value?

    We don’t have data to support your suggestion, but it seems like a very reasonable idea

      What is the R value? Will this completely cove a single garage door
      ByFeb 6, 2026

      Answer This Question

      That’s a great question. For Radiant Barrier type products there is not a thermal rating like R-value. Radiant Barrier blocks radiant heat from the sun and the calculations you wanna make are based on emissivity. These Radiant Barrier products will block 95% of the radiant heat. On Home Depot there is a product for a one car garage and a two car garage. Those are two different SKUs

        If I’m also using foam board for more insulation for the winter, should I put the foam board on after installing this?
        ByDec 6, 2025
        1 Answer | 
        Answer This Question

        You certainly can and not a bad idea. This Radiant Barrier will simply keep out radiant heat and does have some insulation properties if that’s also what you’re looking for. However, if you can get foam board on there as well, it will give you that much more insulation power for the winter.

          is this product used in conjunction with another product to increase the R-Value? Is it safe to do so?
          ByFeb 5, 2025
          1 Answer | 
          Answer This Question

          Great question. This product is designed to insulate the garage, but from a winterizing standpoint, the R-value for the product itself is relatively low, but against the garage door with an air gap it’s increases the R-value. But you can use another product with it if you wish. However, the primary benefit is the super high reflectivity to repel heat from the garage area. The Radiant Barrier does a fantastic job of that. But it also insulates for cold as well. I hope that helps.

            I wasted my money. I couldn’t tell one bit of difference and what is given to adhere it is child’s play!!! Don’t waste your money. One extremely disappointed customer.

            Did not stay up long
            The material seems OK, however it is mounted to the door by using little 1'x2" pieces of double sided tape, about10 per panel. After about a month, the panels started falling off, as the little tabs were not enough to hold, came detached on the insulation side. I will look for a roll of double sided tape and use all the way around.

              I got my order quick. It was easy to install. I installed it in less than an hour. I noticed a difference in the temperature right away. It went down about 10 degrees as soon as I installed it. Great buy!
