Hi I’m in Corpus Christi, Texas. Is it okay to fasten non-perforated radiant barrier to the bottom of the rafters inside an attic? The problem is I ran short on my initial order of perforated radiant barrier and they sent non perforated radiant barrier instead. I have completed approximately 2/3 of the project and I have 1/3 left to do. Any input is appreciated.
You only need perforated if you are putting the radiant barrier on top of the insulation on the floor.
