Big-is it sacrificing a lot by using 1-2" up front?

Do you guys usually screw the Linacoustic into a stud or a furring strip? Even with a 3" screw it won't make it through 2" of Linacoustic and 2 layers of 5/8th drywall.

just to the drywall. You could hang the whole 100 ft roll bag on a single screw into 1 1/4 inches of Drywall. No need to hit anything.

Alright, great thanks! I figured just drywall would hold it but wasn't sure if that was kind of a no-no.

Just got done doing my front wall and used 3 inch drywall screws and pieces of cardboard sprayed black as washers.

Works perfect.

So you guys are screwing this stuff directly to the back and side walls behind the screen? I think my guy was planning on using some kind of adhesive. Glad I saw this thread.

Yep, just screws.

This is 1/2" linacoustic. Got a 35' roll locally for a great price otherwise I'd have gone with 1" (or even 1/2", plastic, 1/2" sandwich). Used black cabinet screws in corners and just 2" drywall screws for random support.

@BIGmouthinDC , any idea of full weight/dimensions of the 100ft roll off top of your head (approximate is ok)? could i fit in the back row of a sedan? my truck might not be around this weekend (father-in-law borrowing it) and i need to pick my roll up this weekend from a local hvac supplier who brought it in special for me. wondering if i need to call in a favor to a buddy who also has a pickup or if i can squeeze it into a sedan's back seats.

also, have seen lots of reference to 3mm poly/plastic between the 1" layers - can i just use regular 3mm plastic drop clothes? if not, what do you/others use?

if you have a big back seat maybe, 48 inches tall a little larger than a 55 gallon drum. Maybe 50 lbs.

cheapo screws with washers would be my choice, along the top and let the cotton drape down. Maybe a couple at the bottom.

Painted some cardboard black with spray paint and cut them into small squares. Then just popped drywall screws through them and it worked perfect.

I'll pass on advice I got years ago on this forum and have been using. A trick to get cheap plastic washers is to buy roofing nails at your local HW store like these:

https://www.homedepot.com/p/Grip-Rit...CAP1/100198483

I then pull out the nail and put a 3 inch drywall screw through it into the Linacoustic or OC703 or Quest AI panel. Seems to hold really well.
For screen wall you'd need to spray the washers black of course.

YEP! A tight fit, but I got my roll in the back seat of a BMW 330i.

If you have small pieces or lining a duct boot or just need it to stay in place to make installation easier, this stuff worked awesome on duct liner:

Getting ready to treat my room and had a few questions. Does the lincoustic go from floor to ceiling on the screen wall and do you also treat the back wall the same?

I don't have an AT screen so how do I hang the screen. Does it have any space between it and the Lincoustics.

Thanks

Yes whole screen wall, not all the back wall, use spacers (blocks of wood) to mount the screen proud of the wall.

I used these "Grip Fast® 1-3/4" White Plastic Finishing Washer" to attach Roxul to the ceiling in between the floor joists for my current build. I bought a 1000 count box from Menards and I have plenty left over so I will use them for attaching Linacoustic behind the screen wall and spray paint them after there installed. I would have provided the link to Menards but their website is down right now.

Since I am just about to embark on this part of my build, I figured I might as well ask (even if it is a dumb question)---is this the proper construction sequence?

1) roll out 1" linacoustic, screw to drywall
2) roll out 6mil plastic, screw through linacoustic to drywall
3) roll out 1" linacoustic, screw through plastic and first layer of linacoustic to drywall

That seems the most natural to me, though I wasn't sure whether some people instead make the sandwich first, then mount the entire thing up to the wall all at once with a single layer of screws. Seems like that would be nearly impossible to do with just one person, however.

I use the minimum number of screws to attach the first layer. Simply tuck the plastic over the top edge of the first layer and let it hang , then attach the second layer with enough screw to hold everything in place.

Thanks- I would much prefer to attach it using the least number of screws as well, so my original system seemed like massive overkill.
