I thought the title would grab attention. But neways, i'm wondering if 2.25" mdf would be strong enough not to brace in long runs. I'm gunna have panels spanning 48x48" or there about and i was wondering if i used 2.25" mdf would i still have to brace. Thank you.

wow. that IS thick wood. HEAVY TOO. Brace, just in case. Long pieces are easier to get moving, long AND wide, even though it is over 2" thick, I'd brace.

 

PICS of THIS project for sure.

if you have access to 1" it'll be cheaper.

 

What kind of vehicle is it, and do you plan on actually driving it?

Laminate 2 1" peices, and you shouldnt require bracing. 1" MDF BARELY flexes on a whole sheet, so id say that 2 laminted together wouldnt budge.

2 peices of 3/4 glued together would work the best, if not 1 inch should work and not flex , and whoever said a whole sheet of MDF doesnt bend , yeah right, have 2 people hold each end and it'll bend noticable, even one inch will, but i doubt at 4ft by 4 ft

That was me that said that, and of course it bends a little(thats why it says HARDLY), but not nearly as much as 3/4" thus the reason why i said to laminate 2 together.

actually this question is for a wall, i wanted to triple up 3/4" mdf on the big big pieces because thats where the speakers will actually be mounted+ the "dance floor" because it'll be rather large as well. Thanks for the answers though, i should be starting this on saturday or sunday so pics will soon follow.

2 will be enough, but if you want three, just make sure enough pressure is applyed when glueing the 3 togther, since 3 3/4 why not just 2 1" much easier

i had 2 layers of .75" on all the sides except the front baffle which was 3 layers...if i was going to do it again, id put 2 layers of 1" on all and 3 for the front baffle.

 

Plan on doing atleast 4-5" walls in the van though, so like I said..if you plan on actually driving the thing, you should be fine with what you have planned..if youre not, and its for spl...overkill it 2x.

 

you wont find 1" at howes or hd, but a lumber yard should have it...hell get something bigger if they have it.

A local lumberyard should stock it...most home improvement places don't stock anything over 3/4" in MDF or BB...

if this is for SPL and you're worried about flexing, do 1 piece of MDF, 2 inches of concrete, then 1 inch of mdf on the outside, like sandwich some concrete, you can get 48x48 pieces of lead in there too, you can buy those at a roofing supply store.

 

what is this project for?

 

the ultimate wooferbox is made of 9 inch thick lead so they say.. but for cars, concrete with lead sheets is as good as you can get

JUST THROWING IT OUT THERE.....BUT....couldnt you just get 1" MDF, get a bunch of sheet metal, throw dynamat on the sheet metal and then sandwhich that in between the 2 pieces of 1" MDF, so it wont resonate.?
