"Did you install them directly under the decking or leave an air gap?"
I second this question—installation details really do matter. When I tried reflective barriers, I initially skipped the air gap (rookie mistake, I know...) and barely noticed any improvement. After redoing it properly with a small gap, things got noticeably better. Still skeptical they're a magic bullet, but done right, they can definitely help chip away at the heat issue.
Yep, learned the hard way myself that skipping the air gap makes reflective barriers almost pointless. Good on you for giving it another go—small details like that often make or break a project.
Totally agree, skipping that air gap is a rookie mistake I made once too. Reflective barriers need that breathing room to actually perform—otherwise you're just wasting money. Learned that lesson insulating my attic...the difference afterward was night and day.
Yeah, that air gap makes all the difference. When I first started working on roofs, I didn't get why we couldn't just sandwich everything tight—seemed logical at the time. But once you see how reflective barriers actually work, it clicks. Heat needs somewhere to bounce around and dissipate, otherwise you're basically trapping it in place. Glad you got your attic sorted out; it's always satisfying when you finally nail down the right method and see the results firsthand.
I was skeptical about the whole air gap thing at first too. When we redid our attic insulation, I figured tighter was better—seemed logical, right? But after one brutal summer, I learned firsthand that heat needs space to move around...lesson learned the sweaty way.
