OC703 "straddling" corner question

I have some OC703 type material (compressed duct board) that I will be using to build some bass traps.

I've researched that I should leave the foil backing on one side, and face that towards the room. Each duct board sheet is 1" thick. I will be stacking these to at least 4", to build bass traps for straddling the corners.

Will a stack of 6" be that much better than 4" when straddling corners?

Thanks,
Marc

It depends. If you have only a limited amount of OC then make them 4". Covering more corner area of 4" will be more effective then less area covering with 6" thick panels. It is about thickness but also about over all coverage.

You are somewhat modest with your post. 703 is considered to be at best when 4" thick. For thicker absorbers, an air gap is used for the balance.

Like always, you do great posts Glenn.

Well we don't use 703 but still implore a air gap with all panels that can be straddled. But if you use 703 and make it a solid 6" and straddle the corner it does work better then a solid 4". So I guess we agree!
