Questions & Answers

is this rigid or bendable

is this rigid or bendable
Asked by: chip
It is surprisingly bendable. As long as you keep the films at both sides, the foam core will not break by moderate degree of bending. I used this product to insulate garage door - cut pieces were bent and inserted into 'slots' of garage door panel. Total 60 pieces were bent, some of the pieces had to be bent to an extreme degree, but not a single one broke.

Can I use liquid nail to attach PVC trim boards to the insulating sheathing?
Asked by: ozzie
I don't know why not. It's like Styrofoam so as long as the glue doesn't melt the foam it should work. Again it's Styrofoam so not sure of your application but the sheets are not very strong. Hope this helps.

Can it be used under a pool

Are you talking about an above ground pool? Then yes. We have been known to use this under our seasonal portable ice rinks as well.

Asked by: Dale
You can cover this with colored joint compound depending on the effect that your going for. I've used acrylic paint. If you cover it in the joint compound as it comes out then you can even spray paint it. Just make sure you have it covered completely or it will melt away underneath the joint compound.

1/2 in. x 4 ft. x 8 ft. R-1.93 Insulating Sheathing is rated 4.8 out of 5 by 11.
Rated 5 out of 5 by from I used this product to insulate garage door to shield from hot desert sun with fantastic results.... I used this product to insulate garage door to shield from hot desert sun with fantastic results. Aesthetic is bonus - just look at the picture. It is unbelievable that I used no glue, no screw, and no tape, yet they are completely held in place, and completely removable if I wish to. Read on if you want to know how. Problem: I live in a desert and my garage becomes uninhabitable in summer months, often exceeding 120 F - the temperature at which you are not recommended to store most spray can bottles. The cause of heat is obviously my east-south facing metal garage doors, which collectively turn into 200 ft2 teppanyaki grill. Standing closer to the garage door, you can feel the radiation coming from the heated garage door panels. Alternatives: I looked for the best known methods to shield garage from heat. One common way is to glue or tape Reflectix (basically a bubble wrap with reflective film on both sides) on garage door. Or you can buy 'insulation kit', which costs small fortune, and may require spring tension adjustment due to extra weight. Lastly, you can cut and 'attach' foam panel with reflective film on it, which is the route that I took. Requirements: It is desirable if the solution is - lightweight so that spring tension doesn't have to be changed - easily removable in case you need to repair garage door - clean finish and look that adds value - minimally intrusive to existing structure - simple so that you don't have to dismantle garage door during installation One thing I didn't care about was shielding from cold in winter, but I think this will help in winter too. The solution: After close examination of the design of garage door metal frame, I realized I can insert cut pieces of foam panel into the garage door and they will be held in place by natural tension of the foam if the foam panels were cut with precision. The edge of the metal door frame actually works as finishing trim, which will look very good. There are two potential execution issues with this plan. One is how to insert the foam panels, and the other is once foam panel is inserted, then how to bring the panel closer to the edge and give some tension. Solution to the first problem is to buy thin panel so that I can bend.1/2 inch panel works like charm. You will be surprised how bendable this panel is. As long as you don't remove films on both sides, this panel can take quite amount of bending force without breaking. So, what you have to do is just bend a cut piece of this panel and slide the panel in. Now, once the panel is in, I needed it to get closer to the metal edge trim to make it flush. I first inserted long stick into the holes on the side of metal frame, and wiggled the stick to move the panel front and flush. I also used painters tape to 'lift and pull front' the inserted panel. (I could have used some kind of suction cup to achieve the same thing..)
