Foam Core Reflective Insulation Garage Door Double Foil 21 Inch x 16ft Roll Energy Star Rated Made in USA (1)

I have a Clopay 2-car garage door comprised of 4 rows of 4 panels. The top row have the plexiglas lights with grilles in the glass. I will use the clear plastic heat-shrink window insulating film for those.I liked how this was sold/packaged. Each roll fills the panels in 1 horizontal row, so I could buy only 3 rolls. Other products required coverage for the full 2-car garage door, which I didn't need on the top row of windows. I bought the double sided tape, but didn't use it. The material is about 3/8" wider than the panels, so the cut panels form a friction fit, along with creating their own air space between the door and the material. Or, you can mash it up tight to the door.The material cuts easily with household scissors.

The product states it is 21 inches x 16 feet (192 inches). Per their information, I purchased 3 boxes to complete my project. In actuality each box contains 4 rolls of 201 inches, which is 804 inches of material. The product fit very good and cooled my garage, but I was unhappy with the seller who still charged me $18.86 to return the product, after our discussion. Be aware of inaccurate measurement description.

I have a well insulated garage and 3/4" Styrofoam panels installed DIY in both of my gagage doors. I bought this foil/foam insulation to reduce heat flux, help reflect heat back into the garage in winter and reflect radiant heat in the other direction in summer. I placed this insulation on the metal door frame with an air gap between it and the the styrofoam. The winter results have so far been great. The surface of the door with this insulation is 6 F warmer than the door with just the styrofoam. The photos in this review were taken when the outside temp was about 38 F. The foil/foam forms an almost air tight cavity with the garage door when it's fully taped/glued to the door. I used heavy duty doublesided tape for the job. The surface of the foil foam is uniformly wrinkled but there are no creases. I think it looks good. Also, any gaps or holes after installing, such as near hinges or handles, are easy to disguise/hide with plain aluminum HVAC tape. Just wrinkle up the tape after you apply it and it will blend right in.Also, the customer service from seller Trade Winds was Awesome!

The media could not be loaded.  The foam core came rolled into one big roll. There were (4) 16' long strips that were easy to cut to the 96" lengths I needed for my 2-car garage. I bought double sided tape but didn't need it. The insulation is stiff enough that it maintains it's position in the door panel even when it sits overhead...very impressive. I hope it helps cool the garage at least 10° or more and I'll be ecstatic!

Purchased this product and it was very easy to install. It looks nice and does seem to keep our garage warmer. Seller was very helpful! Would recommend!

It seems to help some with the garage temperatures so far. My problem is I just can't get the insulation to actually attach to the garage door. Despite various ways yo get it to stick.Despite not getting the insulation to stick, it seems a tight enough fit on the garage door to not fall off. Let's see how next summer goes to really see how the insulation works.

Worked perfectly! Even double layers!

Adding this insulation to the garage doors has made the heat rating on the doors about 10 degrees cooler. Used spray on adhesive to hold the insulation onto the door panels. Easy to do.
