Well, it could help but it's pretty fragile and brittle stuff to not cover it up. Just about any hit or bump on it could damage it. (It's like popcorn; light and fluffy and real easy to break. It weighs nothing.)

is it white?

It's like styrofoam peanuts: it could protect against shock. But no, it is definitely NOT puncture proof! It is SO easy to puncture! You could just poke a hole in it with your finger.

Can this product be used to insulate a garage door??

Asked by Seth June 27, 2020

Answer

Yes, that is what I used it for. On mine it was held in nicely by the terminal bends in the garage door panels and the vertical braces. If you use three pieces per panel you can insert it snugly without breaking the panel while installing it. Cut three panels to fit the door section between braces. Insert the foam pieces in the center of the door panel and slide one piece to the left, one piece to the right and the center piece last to fill in the center and fit snugly between the other two pieces. Repeat the process for the area between the braces on all door sections and the foam will stay in place with no adhesive required.

Thank you, ncJohn. That answers my question completely. I’m now looking at R-Tech R-385 Insulating Sheathing, 1”x4’x8’. Wondering if that would be a more appropriate alternative?

No! This insulation could melt or ignite creating hazardous fumes. I would recommend a material made oc ceramic or heat tolerant fiberglass (not regular wall/ceiling batts) be used.

This foam has no structural rigidity. It would just crumble and break apart.

I would think not. This is insulation that is like the packing that is form fitted around items for shipping. It has no structural strength, either compression or shear.

The photo shows a product that looks blue, so I thought it was extruded polystyrene. This is "Styrofoam" (expanded polystyrene), which is fragile and messy (when you cut it, little bits of it fly off and go everywhere). Because it looked blue, I thought it was extruded polystyrene, and so I had to return it because this stuff would break if you tried to make a duct out of it.

Though I would recommend for the price size and novice ability. I say be prepared for it to not be quite like the directions. It’s not as clean of a break as one would like and messy. After all it is just styrofoam. Served it purpose for us with some metal tape to insulate a outdoor cat house. Will know more When real cold sets in.

Great idea. The foam board is sized to fit between the studs of an unfinished wall.I found, however, most studs are not exactly 14 1/2 inches apart and are frequently curved. So, involves lots of cutting and shaping. In practice, it took lots of extra time to do the job.
