Sorry to rehash this old topic, but I still don't have a "clear" answer in my mind.


Attaching this stuff to the front walls...regardless of thickness recommendation these days...

1. How does it actually get attached to the wall?
2. Does it go straight up against the drywall?
3. Finally which way does it need to face? I see this round peg like things with washers (?) in pics but have no clue what they are (example below)

I will be fabric wrapping it so I will have a frame around it for the staples...have to figure out the best way to wrap and hide staples here as well haha


many thanks!

I JUST put mine up...so I will tell you how I did it...hope it was correct

I put Spray adhesive on the drywall to help hold while I used drywall screws with roofing washers on them..

I put the faced side OUT towards the theater...

I used 3mil poly in betyween the two layers

I am still deciding if i need to do the walls and ceiling behind the screen...anyone?

Could just use some screws with big washers in a few strategic place to hold it up as well, if you don't want to use any glue or anything like that. My front wall was framed out and I put Roxul AFB in between the studs and speaker frabric will go over all of that as well, a little different though then what you will be doing. On my back wall though I do plan on have Linacoustic 2" installed. Not sure exactly how it will end up be attached. I have some framing on that wall where my fabric will be going since the whole back wall is fabric, so ill probably cut out big squares of fabric to go in those frames. It will go straight up against the drywall, no need to finish it off with paint or anything as you will never see it. Although i suggest getting some acoustic caulk and filling all the dry wall seams with that.

forget about the glue and fumes, I'm into just screwing. get the big headed PowerHead screws marketed by Fastcap and on Amazon.

Yep, that's the one. It's like having a small washer built in.

If you want to get fancy, you can get the black ones to match the Linacoustic:

Or just get the black plastic fastcaps:

The other common method is to use the plastic Grip-Rite washers on drywall screws:

I get the three inch power head screws, put the first layer up with drywall screws and the second with the big guys. Just a FYI my first theater I used only a handful of naked drywall screws and that linacoustic hasn't moved in the years it's been there. Just screw them until the head touches the coated surface, no more.

Are you using poly between layers? I may get 2" of Lino up and wonder if 2 1" plus poly is better than 2" by itself? Quicker with the one install

 

[BIGmouthinDC]

there is a reason for the poly. that is all my DND agreement will allow me to say.

Is there a standard poly people are using these days? I know nothing about poly so be gentle haha

Per both Toole and Erskine. Fiberglass insulation in front corners for the purposes of bass trapping is waste of money. At the front corners standing waves are at their highest pressure level but lowest velocity. Fiberglass is a velocity bass absorber. You want to make a dent on bass you need membrane absorbers. Of course you should know what frequencies you need to tame because membrane traps are effective over certain frequencies. So what to do? Put a layer of 3mil plastic between the two layers of linacoustic on the front wall and it will behave as a membrane trap of sorts.

So now I am further confused. Are you saying corner bass traps are a waste of time/$?

My plan...
Linacoustic the front wall (2 layers with poly in middle)
Corner triangle bass traps (floor to ceiling) made out of pink or oc703 equivalent

If I am steering wrong please advise. Many thanks !

I would like know if there are any benefits to running linacoustic directly behind a non-AT screen?

 

[BIGmouthinDC]

unfortunately a non AT screen is not sound proof sound will get back there via drum head like action and then bounce off the wall and back through the drum head.
