Dude, don't let Paulie loose with the sawszall anymore! He has no idea what he is doing and he just shitcanned a lot of your $$'s on the foam he destroyed! Someone earlier treied to tell you to leave the foam up and install the drywall over it! Also I agree with "bimmer1980" Paulie just eliminated your strength in the ceiling joists and by the way it looks like what we all call a 2 X 4 not a 2 X 3 even though it measures less than that.
Just my $.02
yikes...... "notched the beams for the cable..." that is a huge no-no for floor joists, roof rafters, etc. You just cut the strength of the beams by a huge factor. Hopefully you didn't cut too many in that manner........
I understand you want to get this done, but the correct way is to drill a hole in the beam. And staying with in the maximum edge distances and end distances. Then the cables are disconnected and routed thru the holes
The bottom of those beams are in tension. Your effect beam size is now the distance from the top to the upper edge of the notch.......
sorry to be the bearer of bad news..........
Clearly Paulie knows nothing..... Or better yet maybe, the person who saw the garage first hand and corrected the issues in this garage is better informed than the people who are sitting behind there desk and looking at a handful of images to determine what is the best solution to problems that Andrew is facing in his garage.
So im going to give you some facts so that you can reevaluate what you feel is in Andrews best interest and ummmm "safety"
Andrew decided to install 1/2" Foam board that carries a R Value of 2, because he felt that it would be the easiest material to work with since he has no experience hanging sheetrock ... I had already advised him that the foam is easily combustable but he still went ahead and decided to install it.
Being that he only finished about 1/4 of the ceiling with this foam, I recommended that he not waste any more money purchasing more foam since he already installed R-19 insulation and his biggest worry in this garage is the 10' steel gate that has no gaskets or insulation at all.... His money is better spent on correcting the garage door draft than finishing the ceiling in 1/2" EPS foam...
The 2nd problem was that all the lateral supports placed between the joists were about 1/2" below the joist and needed to be corrected before he would be able to install any sheetrock since the ceiling wasn't flat... So i removed about 6 or 7 boards and chiseled the bottoms off whatever wood was in the way.
And now onto the reason behind notching for the wires.... I had already advised Andrew that the electrician should of just drilled the beams and ran the wires, but he simple took the easy road and decided to staple them to the ceiling joist I had absolutely no interest in disassembling every light fixture to drill the holes so i took the easy route and notched maybe 4 or 5 beams
As a general rule of thumb the joist can be safely notched 1/6 there size and since this structure was constructed with Dimensional 2x8 lumber I can safely notch 1 1/4" deep into the beam.
The joist were also placed 12" O.C in this particular building and I notched maybe 5 beams in the entire ceiling to accommodate the wiring.
So of the aprox 29 joists in the ceiling .... 24 are still fully intact...
So thanks for all the kind words
