What is the purpose of leaving the gap at the eave and the ridge vent in a vented attic? Won't the eave vents still pull the air up to the ridge regardless? Is air circulation required in the area 'under' the reflectix and this is the source?
Yeah, you really need airflow under the reflectix. The radiant heat from the roof deck is being bounced back at the roof deck, so the bulk of the attic heat is going to be trapped there. If you don’t ventilate that area, you’re going to end up cooking your roof.
My home is ranch style- one cannot stand in it. you are basically doing an army army crawl on your belly. how can I install this in this type of roof space. I have probably have less than 3 inches of blown insulation- super old- been here 20 years and I have never reinsulated.
The main question is: What is the attic temperature difference before and after the Reflectix?
What type of staples do you recommend with the install?

That must be to cool the attic (from the soffit vents).

Looks like you’ll be army-crawling a bit. Fixing the venting will be a better ROI and it would be a little easier.
