Just bought 7 sheets for a basement remodel, I removed the drywall to find out that the batt was installed directly on the concrete walls 🤦‍♂ batt was humid , what a shame this house is almost new. Now I bought Durofoam , to put on the concrete, then frame then put back some 2x4 batt. Now it will stop any cold draft from entering this room in the basement. I will have to do this all around my basement.

What is the max temp range?! I am thinking of using it for my custom sauna. Thanks!

Do I still need fiberglass insulation in between my studs ?

Can I leave the boards exposed without drywall in a garage?

Short answer, NO. This product is combustible. A protective barrier or thermal barrier is required. Per example, brick flame spread rating is 0 , Type X ( fire resistant gypsum ) Drywall is 15 , and this product is 290. So in case of fire, this product will spread the flame pretty rapidly and the smoke developed classification is over 500, so it means it will make a lot of smoke.

probably, but I think you might want framing to do organizing cabinets and storage shelves. I'm planning on using this to insulate sound and to increase rigidity of floor where I plan on putting a large aquarium and custom cabinets on the walls. If it doesn't bother you or you don't need to break their plane (vapour barrier) I don't see why not

Just don't agree with gypse in basements. Problem occurs, what a mesd. That's just me...
