Question 1

Stapled under the roof vs laid over insulation batts that are between ceiling joists. Which is a better option?

Accepted Answer

We recommend stapling up to the underside of the roof rafters in order to reduce the temperature in the entire attic space. However, this product is not designed for stapling so if you want to staple us as we recommend, please look for our Xtreme or Ultima radiant barrier on Amazon which IS designed to be stapled.

Question 2

Can this be put on top of shingles then 1x4 on top then metal roof on top of 1x4?

Accepted Answer

I am extremely interested in saving money and anything that I can apply to the renovation of my house whether it be by applications or materials, I highly research and learn the best methods to use myself. Now regarding your application of applying the radiant barrier directly on top of shingles, then mounting 1x4 studs over that then mounting tin(r panel) directly on top of that?……. I wouldn’t see there being any problem since the ribs in the tin provide a channel for air flow to be carried up and out. You just have to keep in mind that you must provide a channel of air flow. Keeping in mind that hot air rises, you should be fine. Cross sections of your 1x4 timber can trap air if you’re running them horizontally, but if you are using r panel type of tin the large folds that bend upward will provide this channel needed for air flow to continue upward. If you’re using the other type of tin( 5V crimp), this type of tin doesn’t have the large bends needed for air flow, or I should say it does but they are very small and has much more surface area that’ll cripple air flow when mounted. The exception to this I think is if you stagger your 1x4 studs in a zig zag manner to not impede the air flow. If this was my project, I’d cut the 1x4 timber the width of the tin as it will be mounted. Let’s say 32 inches, mount your 1x4 onto the radiant barrier roof, then mount the next 1x4 8 inches lower, the effect you’ll end up with is like the “Donkey Kong” game, where the barrels roll down and they keep rolling left to right in a staggered manner. Except in your case you’re creating a path for air to flow up and out once your 5V crimp tin has been mounted down on your 1x4s. Not sure how much work you willing to perform but I hope my ideas give you some options. Best of luck on your project friend.
