I can get rigid insulation at Home Depot in 3/4", but I'm not finding flexible insulation for the curved parts. Can anyone recommend a type/source of flexible insulation?

You talking the pink sheets? They will curve just fine. Got mine from HD and wrapped right around the bends.

I used three layers of 1/2" foam which works just fine and can be installed in a tight radius.

I used hot water tank blankets to insulate mine. I cut and fitted them between the spars.

You're gonna have to cut your big sheets of rigid to fit and lay between the spars--it doesn't have to actually bend.

Even if your spars are 24" on center, it'll fit in there without any real bending. And if your spars are closer together, that's even LESS of a problem.

Know what I mean?

If your tear is 4' wide and your spars are 24" on center for example, you're gonna cut each piece of insulation 24" high (minus a bit) and 48" wide (minus a bit).

Do you plan 3/4" total thickness for roof insulation, or 2 layers for a total of 1 1/2"? If the latter, you can kerf--slice into it--to make it bend and fit the 2 layers in there between the spars.

Stick with rigid foam and stay away from roll insulation, which can create problems for you if you develop any leaks.

Here is how I got my Insulation to fit
I cut grooves on the bottom side.


I also used some scrap quarter round to hold it in too

well, I'm off to HD tonight to see what I can do. I hadn't thought of getting thinner sheets and bending them.


No fiberglass insulation, i hate that stuff.

yes, HD has just the thing, a flexible foam insulation (white with plastic on both sides.) Less than $9 for a 4x8 sheet in 3/4 ".



I had a hilarious scene in the parking lot trying to load very lightweight 4x8 material onto my roof rack in a wind storm. I was nearly carried away
