A: Thank you for your recent inquiry with The Home Depot. The air gap is not essential for the installation of the Reach Barrier it improves the thermal performance of the product . We appreciate your business and look foward to serving you in the future.
A: When they don't mention the R-Value that means it's not high enough to use in their ads. To get any "value" out of it, a 3-4 R-Value rating should be adequate in mild climates, more like R-8 or higher for extreme hot or cold climates...in my experience.
A: Don't know why you wouldn't want to use both, that is what the kit comes with. More insulation options the better!
A: I did both on mine and have zero regrets. It made a huge difference in the summer time in my garage where temperatures are regularly reach 100.
A: We didn’t try both. We just used styrofoam and have noticed a difference in how well the temperature is regulated in the garage.
