How Much Attic Insulation Do I Need for Summer Comfort?
Asked by SunnyDayz123
I'm currently dealing with an attic that reaches 112°F, even though it's only in the high 80s outside. I've attached a photo of my attic here: [https://imgur.com/a/yDrlblV](https://imgur.com/a/yDrlblV). I've got a fan in the attic, but I suspect it might need upgrading. I also store decorations and some winter gear like sleds up there. I'm worried about the insulation since I can see the top of some of the joists. If I find that I need more insulation, can I use 2x4s and more plywood to raise it above the joists?

Hey! The first thing to check is local building codes. For Maryland, you should be around R-49 for attic insulation. If you can see the top of the joists, that likely means you need more insulation. What's the type? If it's blow-in, just reaching the joists isn't enough. If it's batt insulation, adding another layer could definitely help! Using 2x4s to set up a deck in the attic for storage is a feasible idea, just make sure it’s safe and secure!

I'd definitely recommend sealing any air leaks and adding more insulation if you can swing it. It’s a lot of work, but your home's comfort will thank you! And a home energy audit sounds like a smart move – you might find some financially beneficial rebates to help with the costs.
MaryMaryQuiteContrary: Yeah, I scheduled one with my local electric company too! I'm curious what they'll suggest.

Honestly, I think adding insulation can really transform your space. When we topped up ours, it made a huge difference in our cooling bills during summer and heating bills in winter. After we increased our R-value from around R30 to R50, we noticed that upstairs temperatures leveled out. It was definitely worth it!

But isn't insulation just a myth for summer heat? I feel like people have wild misconceptions about what insulation does...
SunnyDayz123: Nah, I’d have to disagree! I definitely noticed a difference in my house after insulating. It keeps the heat out during those summer days!
