anyone from ontario, canada .... info needed.

Hey guys Im just about to drywall my attached garage and i was wondering if there is a special type of drywall I have to use for code (because the garage is attached to the house and the house is a semi-detached)... I had bought some cgc humitek and i hope this meets code.....

I drywalled my garage just for appearance sake a long time ago & I
doubt there is a requirement in the building code that pertains to drywall in a garage. Why not google the info. ?

Sorry I cant definitively help you with your drywall question, but I don't think it matters as all "fire codes" needed to be addressed previously. I would however use some type of paperless/mold resistant drywall. Garages up here do tend to create moisture in the winter when you heat them to work then let them cool again. And again in the summer if you wash vehicles inside.
Just wanted to say HI to a fellow motorcycle riding Ontarian!
I'm just about dead center of Southern Ontario, where abouts are you? (P.M. that if you like)

im in ottawa. and thanks.... I have purchased the paperless "humidek" from cgc.... It is meant for high moisture area's but like I said I know there is some type of law for a garage that is attached to a house........ the guys at home depot said that humidek stuff i bought does not meet code....

Hey, I'm in Ottawa too!

I just finished my garage with mostly OSB, but *I think* there is a thickness requirement for garage walls that are attached to the house (for a higher fire rating). If I'm not mistaken it would have to be 5/8" instead of 1/2". Don't quote me on this, though. Do some googling and see what you can find. FWIW the drywall I removed from my walls (that the builder installed) was 5/8" thickness. My townhouse was built late last year.

yeah i know the ceiling has to be 5/8 think but the walls can be 1/2" but have to have a fire rating of atleast 1 hour

 

[q20v]

Ah ok, thanks for clearing that up.

 

[diovol]

glad i could help finally hahaha... that humidek stuff i bought also cost $16/sheet instead of $8

 

[q20v]

Holy snap! How big is your garage? Hopefully it turns out that it IS to code and you can use it!

 

[diovol]

I took the humidek stuff back and used normal cgc gypsum at $8..... also i found out that the walls only have to be fume proof not so much fire proof........ the 1/2" is only rated @30 minute fire proof while the 5/8 is 1 hour....... atleast thats what the old timer told me at home depot.....

 

[logical]

Not that it helps you any but in the USA 5/8 is generally required on any wall common to the house only.

If im not mistaken 5/8 for ceiling and for walls adjoining living spaces. southern ontario Amherstburg area

what about a wall that is not adjoining to a living space but above part of that wall is the master bedroom..... is it ok to do the whole thing in 1/2" because the first 2/3rds of that wall has just its own attic overtop but then the last 6 feet or so is part of a bedroom but on the outside of the wall is just the yard.....

 

[diovol]

cant find info on this stuff anywhere....

From what I remember from building code classes, a fire separation of 1 hour is needed between a garage and a living space. So if your wall on one side is you kitchen the the other the garage you need 5/8" (or two layers of 1/2" ship lapped). If your bedroom is above the garage you need also the 1 hour rating. An exterior wall doesnt need anything by code. I like to use the two layers of 1/2" you can then hide your seams from teh first layer with the second, and it helps to decrease the chances of fumes if the joints crack after a few years.

To answer your post about the bedroom wall... I would suggest goin the whole wall in either 1 layer of 5/8 or two of 1/2". better to be safe the sorry, that and trying to only do the wall that touches the living space with the proper amount will leave the rest of the wall with a slightly weird look having some stick our 1/8-1/2" more then the rest of teh wall... if that makes sense.

My house was 3 yrs old when I bought it & the builders drywalled the garage for the original owner.I wash my car in the garage & haven't had any moisture issues yet,not to mention snow & slush in the winter.It's also well insulated,unheated & the inside temp is always 10 degrees warmer than the outside temperature.

I'm just fininshing mine in King. I was told it is a code requirement to vapor barrier and tuck tape any garage attached to a dwelling.

Like R6 Racer said, all code requirements should have been addressed before you moved in and any common walls between the garage and living space should have been taped and drywalled, drywall is used because it is the cheapest and most convenient. this common wall only has to be vapour proof not fire proof and can be achieved by using plywood or OSB and caulking the joints.
