Axiom Home Page Forums General Discussion Home Theater Lets plan a theater space

Nope under a 2 storey. That cutout was the future home of LVL. Previous beam sat under floor joist atop the offending column.

Waiting for shoring walls to come down. Then pics. Today was another busy and chemical filled day. Promised my buddy I'd wait to pull the walls down together. A ceremonial unveiling.

Ok one pic. The more polite one. Lol.

Either your cooking meth or working on home renovation.

Peter, Peter! I always held you in such high regard as a keeper and guardian of the language. How could you let me down like this? Go, right now, to the bathroom mirror with a Sharpie and draw an apostrophe on your forehead!

You're lucky you live in Canada, Trevor, because everything in that picture would be a U.S. code violation. Nice hazmat suit, though.
I'm kidding, but not about the suit.

edit: Wait! I just though of a meme for your pic.
"Living so for from the epicenter, friends found Trevor's fear of ebola to be unfounded."

Would it be impolite to ask what is holding your main floor up between <column gone> and <LVL beam installed> ?

So, there has been some concern about the removal of the column. Here's how it works. The new LVL beam clear spans the space where the old column used to support the main floor. This is all spec'd by an engineer (who has yet to send me the bill for some reason.) Detailed drawings are provided based on caluclated loads etc. engineer stuff. They spec the LVL size, bolt patterns, etc.

The temp walls are down and boy o boy am I excited!! The pics earlier were from yesterday where we got the beam up and installed. Here is where we were when we set the tools down. I WAS PUMPED!!



We had the LVL assembled and up in the pocket and sitting on the remaining column we were tying into. Today I bolted the beam together and finished installing the remaining joist hangers.

DIY tip, if you use a plastic bag to remove goop from your hands you dont get the paper towel lint going on. PL premium is a bitch to get off your hands.

Here is where I was at by lunch today:



I spent the afternoon spray foaming the Rim joist and the screen side of the theater ceiling. I ran out before I got to the second half. Oh well. I've already used 2 kits and at 300$ a pop they are too expensive to buy 2 more to finish. I'll double up batt insulation in the back 1/2 of the room.

Here is how the foam looks:



After my building pal got off work we took down the shoring walls and stood back to appreciate the job. What a job it is. Before you do anything like this ask yourself one thing. How home theater obsessed am I? I guess you already know how I answered.

Here is the current state of affairs. There are a couple of shots to let you know how the clear span is secured to the existing structure.








Lastly this is the "after the hurricane set the house back down" pic. Code violations were mentioned before. If you can find them all in this pic, you win a prize. All this stuff is very temp btw. I think I'm going to wear the suit to bed tonight. Kinda warm and comfy. Off to eat pizza.

Be careful about doubling up the batt insulation in the other half of the theater. A decent air gap helps with sound proofing. The spray insulation doesn't do much for sound proofing anyway, but for thermal separation, and the thermal difference between 1 layer of batt vs. cramming in a second layer is very minimal unless insulating an exterior wall.

Ooh, nice. I really like LVL beams -- there's one about 50 feet long holding up my house. A million or so 2x6's support the LVL beam, LVL beam supports the roof, roof stops the walls from falling outwards... or at least that's how the engineer explained it.

Thanks guys.

If I could do it again I would not have spray foamed the ceiling like this. It isn't thick enough to do anything but air seal that area from above. I rationalised it in my head because we have hardwood floors on main. The screen half is directly under the dining area where the chairs skate around on the floor. That side is also where a dishwasher sits above. I have yet to do any real sound tests, but a quick "stomp, talk and scoot chairs while I'm down here" test revealed the sound was only muffled slightly. Still could hear easily... Oh well. At least our farts will stay down there I guess. .

Today I have to jack hammer out the remaining 2" concrete pier and re-secure the existing wiring. We gained 4 1/4" of headroom under the beam. Now I have to decide if I want to sneak a duct alongside it or drop them in the double wall (which is now happening.)

Re. (who has yet to send me the bill for some reason.)

Welcome to PEI.
I had an electrician in during the spring to move an outlet and have not yet received a bill.

I had a different electrician in adding a heating zone over a year ago. Still no bill.

Time since my last bill from the guy who snow blows my lane in the winter... 3 years. 4 maybe? I actually can't remember.

Your engineer will get around to it eventually. Honestly though, I don't know how these guys pay thier bills.
