Hi Frosteh,

Yes moving it sucks... no other way to say it. If I wasn't 6'5" and 235 lbs there is no way I would have done as much as I did. For your answer look at post #145 above.

Looking good! I don't envy you hanging all that MDF.

Just a note, on the forum here, you generally see the ceiling DW/OSB being hung first, then the walls. The next layer starts on the ceiling and then walls again in the same order. This ensures the seams overlap to improve the "seal." I suppose as long as you go in the same order for both layers you will still get the same overlapping of the seams, though.

He still has a gap on the wall, grab a lift and do the ceiling then finish the small portion on wall that's left, then you can turn around and do the 2nd layer of drywall on the ceiling with the lift and then return it, this is of course if your renting one opposed to buying one.

Doing the ceiling first also provides some structural benefit in that the walls help to hold up the border of the ceiling.

Hi all,

Lots of people do it different ways but as I've stated in previous posts, I'm doing it per the plans from Kinetics.

No worries. I bet there are many different versions with no real wrong answer.

The one surface I'm most concerned about is the ceiling as our master bedroom and my daughter's room is right above the theater. I'm considering using Green Glue between the MDF and the Drywall for additional results. That isn't in the plans either so I guess I'm guilty of not following the plans exactly. wink.gif I've been reading up on it and I'm guessing it may add three points or so to the overall STC rating. Anyone out there know for sure or used it with good results?

I would of thought you were using green glue between the layers, walls and ceiling.

Given the strong desire to soundproof that you've shown, you should be using a damping compound everywhere to achieve the results that you want.

The way the house is situated I really just want significant sound reduction in two of the four walls. The ceiling needs to get the king's ransom when it comes to sound proofing. The main reason is that the number one way I'm going to get the "TURN IT DOWN!" buzzkill from the wife will be if it's too loud through the ceiling and to a lesser extent if it's too loud into the kitchen. So really I only care about super high rates of return on those two surfaces. biggrin.gif Still, using Green Glue does peak my curiosity.

If only some of the surfaces are treated then sound will flank through the untreated surfaces and around. For instance, if only the ceiling is treated then sound will go through the walls and then up behind them into the rooms above.

Given the amount of time, effort, and resources that you are putting into this room, Green Glue is a very small investment that will end up giving you much greater results. I would highly recommend it for all of the surfaces in your room.

The thought of sitting under an MDF covered ceiling would require me to change my shorts. What type of fasteners are you using to attach the MDF to the channel?

I have a box of old elastics and a dusty half used bottle of Elmer's glue. wink.gif That should do the trick! Serioiusly though, this is a concern. I used one of those guns with the collated screws for the walls that punches them in quickly and countersinks them. It worked out alright but a good 10-20% punctured the metal channel but didn't really grab on hard. That was using the biggest self tapping collated screw for metal that HD had. I also have boxes of beefier self tapping screws that work great and bite into the metal like a rapid pitbull. The two problems with those are; they are not collated (minor problem), and they have a rounded top and cannot be countersunk. For safety reasons I still want to use these but it will create a space between the drywall and the MDF- not good. But, this then creates a great segway into Green Glue. What if I used a whole bunch of GG on the surface that had the rounded screw heads sticking out???? I'm thinking that the rounded, non-countersunk screws would mean much less if surounded by a fat layer of GG. Any reasonable thoughts from the experts out there (besides statements stating to go magically find perfect countersinking screws)?
post #165 of 755
Do you have Fastenal stores in Hawaii? That's where I would look for the right screws.

Hi Lebon,

I've never heard of them but google says they exist about 20 min away. Thanks for the great tip!!!! Maybe their selection is better than that of HD.

Thanks Dave! Very nice of you to pass that comment along.

If I lived in Hawaii, I think my HT would take a good 25 years to build...lol.

It has to be hard staying in and working when you have what you have outside. Keep up the good work !
post #170 of 755
The green glue isn't going to eat up much room. I bought a tube to use for an air compressor box, and I thought it was going to be a lot thicker. It was like runny peanut butter. It definitely won't compensate for the screw heads.

Thanks BllDo. The more I read about GG the more I was thinking the same thing. It's great to hear some real life confirmation though. wink.gif I'm about to make some calls to Fastenal. Hopefully they have some collated #8 1 1/2" screws for metal. If they don't have anything then I'm going to have to buy something and pay crazy shipping (again) to get it out here. If I had to add up all the shipping costs for the house addition as well as the home theater I have to guess it is somewhere between 6-8 K at this point. eek.gif Good grief.

Thanks Superleo for the nice shoutout. It's my pleasure but any thanks should really go to the young enlisted and NCO's. Have a great day!

I just have to say one thing.... WWWWWWWWWWWWWWWWWWWWWWWWWWOOOOOOOOOOOOOOOOOOOOOOOW!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! That's a massive remodel!! Your kitchen is gorgeous by the way, and I may use the idea of the MDF when I get onto my build.

Thanks Chris. You are correct.... this whole process has been massive and it still isn't finished yet. Thanks for the comments on the Kitchen, it's appreciated.

The holidays have slowed me down a lot but I hope to get back into the swing of things soon. I've received 5 gallons of Green Glue that I'll use in the home theater. The shipping alone cost me 80 dollars per bucket eek.gif Living in Hawaii is great but it's very isolated and all specialty items need to be shipped in which costs an arm and a leg! mad.gif

As always, more to follow......

A new shipment of material arrived to work on. I've read many times here on the forum as well as in magazine articles that mass is an essential component to sound reduction which I have taken to heart so I decided to go with a double layer of 5/8" drywall on top of the 3/4" MDF on all vertical walls. The ceiling can only get one layer of 5/8" drywall on top of 3/4" MDF due to the roof being cantilevered. As such I have a weight limit on how much weight I should safely add per square foot. Knowing this now, I would have obviously requested a change of plans. Live and learn for the next massive house project I hope doesn't come for a very long time.wink.gif And, I've also decided to use three tubes per sheet of Green Glue which I hope will add a little "secret sauce" to the hopefully significant noise reduction ability. There is no such thing as overkill. smile.gif Moving all this material has been a bit of an unpleasant experience but hopefully it's all worth it in the end.


Here is my ceiling with the insulation in place. I used R-30 which is overkill (again).smile.gif Gains on using this incredibly thick stuff is likely minimal over R-13 but, heck, I've gone this far.... why not, right? Helpful suggestion to anyone reading my thread... put the insulation in BEFORE you put on the hat channel and clips. Holy cow, with all that sharp metal and tight fitting area, putting in insulation went from a fast and easy job to a VERY SLOW, moderately pain in the butt job. That ceiling took many hours to complete (I'd rather not fess up to how many exactly as it would be too embarrassing biggrin.gif).

Hey Matt,

Glad to see your daughter and golden in on the action.... Great photo & keep them coming and hopefully this theater will be done in the beginning of next year.wink.gif

Cheers,

Jim

Hi Jim,

Great to see that you're checking in on your...ah, I mean, my theater smile.gif (For those that don't know, I absolutely loved the look of Jim's theater and used his as inspiration for mine... we are both using top-of-the-line Aerial Acoustic speakers too). Since doing things the second time always goes faster, any interest in helping get this theater done???!?!?!?! wink.gif Hopefully this is done soon... probably around the beginning of 2016. Seriously though, I hope I'm in the final stretch of things, we shall see.

Today I started putting up the layers of 5/8" drywall with Green Glue. For those who have not used it... their caulking gun is terrible. After using electrical tape to trap all the air that was being sucked in I finally got enough suction to fill the tube. The stuff is sticky as hell. Once it's on your hands it's quite annoying. It doesn't run down the board at all so at least that minimizes the mess. Here are a few shots:
I'm starting the messy process




Here is my dad helping me lift a panel up so I can screw it in (my folks came out to visit us in Hawaii for Christmas smile.gif)

I just discovered this build tonight - subscribed!!!

I also am using a full-on Kinetics Noise Control decoupling system for my theater, only I am using CWCA isolation brackets for the walls and their new WAVE hangers for the ceiling.

As you can see in my autosignature below, I like the "overdoing" approach you are pursuing with the 3/4" MDF and the 3 tubes of Green Glue per sheet of wallboard! biggrin.gif

And I am very jealous of your equipment, especially that Sony 4K projector. My wife and I went to see "The Hobbit" today and the theater had just installed a new commercial Sony 4K projector. I was quietly thinking to myself what an incredible picture it produced on such a huge screen when MY WIFE actually made a comment on how clear everything looked. Scaling down the same pixel resolution to your size of screen will be phenomenal.

Good luck on slogging through this "right of passage" all of the DIY theater guys go through! Looking forward to more updates.

P.S. - That is an unbelievably cute picture of your daughter on top of all that drywall!!!

Matt,

In many ways you are taking your HT to a level I never even dreamed of. Keep up the good work... It looks like you and the green clue have become close buddies...biggrin.gif
