More garage toys or essentials?

it helps seal everything in and its just the proper way to do it. you would be surprised to see how much stuff can get through the joints in drywall. as far as the insulation goes not sure how much it would affect in a garge but if it were my garage i would tape it. and when i say tape it i mean paper tape it. not finish and smooth it all out.

Just because I"m a skeptic, what are you trying to prevent to get through the cracks in the drywall?

 

[mini=man]

In a building that stays heated all day I can see the heat loss through the cracks, but in a garage where most of the heat will leave as soon as you open the door, I'd be worried about the one spark that could land on the insulation and start a fire. I'd be better off staying in the burning garage than telling my Dad I burnt it down while working on the Jeep

Does drywall actually have that much insulating power, that the tiny gap between the sheets would actually be noticeable?

 

[REWSTER]

insulation got my vote for this reason

A vote for the insulation. With that in there you can take on more odd jobs working on people's cars more comfortably. With more money from doing those jobs you buy yourself a plasma cutter.

you'd be surprised... especially in commercial buildings where they crank their A/C up high.... i work construction, and feeling a/c blow thru the drywall joints does happen. it's like water flowing thru a crack in a plastic tank....

Interesting. I was under the impression that the insulation behind the drywall is what actually did all the work.

Sometimes I give my dad hard reminders about his "mistake." Im also an expert in fire stuff now too :gee:

im not an engineer, only someone who spends some time up on a ladder, with his face against the walls. only reporting my experience....

on occassion, we do jobs in healthcare enviroments that have strict fire safety, they use special power/light switch boxes, they putty arround every pipe, smoke seal every door... its crazy. but i see every one of these as a 'potential' leaking spot of heated/cooled air. its just a matter of HOW sealed you need it. Im SURE, insulating it, but leaving the joints untaped will be plenty fine, this is all in theoretical or chasing down every last penny of your heating and cooling bills phase.

It does most of the work, but taping does help. Insulation is trapped air space, but it is more or less open to the outside air indirectly. By taping, you create a seal on the inside wall. Not a 100% seal, but it does help.
I still wouldn't waste the money to put it up behind the plywood though.

Would spackling the drywall joints do the same thing as tape?

You use the mud over the tape... spackle would just crack and break up without the support.

no you use the mud behind the tape to get the tape to stick. once its dry you can coat the joint with mud to achieve a smooth surface. the paper tape doesnt have any stickynees to it its just paper. you apply mud on the joint then put the paper otape over it and then wipe it down with a knife. this is called fire taping or sound taping. putting a coat over the joints is called finishing. it usually requires 3 coats for a smooth wall finish. 2 for texture. trust me dont be a chump put the drywall under the plywood and tape it up. then hang your plywood over it. xcm was correct about his post as well. i believe he is a glazier so he knows what hes talking about. im a drywaller so now you have 2 professional opinions.

Looks like overwhelming support for insulation. So what are you going to do?
