Spaces on studs under drywall?


Hello,

I demo'd a bathroom that had plaster walls. It was essentially 1/4" drywall with plaster on top. It came to about 3/4" but closer to 7/8" I think. So, this is causing an issue on the wall with the window and the wall with the door, as the jambs are out about 7/8" from the stud. So replacing with 1/2" drywall won't come flush. So I was wondering which of these options were best?

1. I created some spacers to glue to the studs, that are 3/8" thick (from plywood). My only concern with this, is on the exterior wall with the window. As I will have a 3/8" in air gap between the insulation and the vapour barrier. Is that a concern?

2. Use 3/4" drywall, but I wanted to use greenboard or blueboard, which I haven't seen if it comes in 3/4" thickness?

3. Double layer, put 1/4" drywall and then 1/2" drywall? at least then I wouldn't have the air gap?

THanks for any advice or help!

Charlie

Use your furring strips--the small air gap will not be a problem---

I'd go with option number 1. The air space won't cause you any problems.

"I get worried about these stupid small things. Good to know. "------ not a small or stupid thing!

The air gap in front of insulation (better a gap behind it) will give you convective loops, http://findarticles.com/p/articles/m...6/ai_n8582994/ degrading your R-value and giving you heat LOSS; fig. 2a, 2b: http://www.aecb.net/PDFs/Impact_of_thermal_bypass.pdf

Thanks Gary!

Some good reading there for sure. So clearly this isn't the best idea. I'm guessing you would suggest the thicker drywall, or double layering it? Any creative ideas?

I could stick some foam board insulation in each joist cavity then put back the insulation, to make up the 3/8" or so. However, I don't think I"m supposed to have both foam board and vapour barrier...?

On a side note, I am pretty sure my exterior sheathing may be drywall, am I crazy or has anyone seen that before? It would be under aluminum siding. From inside the house, whatever it is, is paper/cardboard backed.

Appreciate everyone's time and help.

It is probably exterior use drywall. You have a problem if poly on the inside and metal siding on the outside = two Class 1 vapor barriers: http://www.buildingscience.com/docum...-barriers/view

Thanks Gary.

Problem is, I believe (could be wrong) that the vapour barrier is code up here. I think it is more of an air movement barrier, but they call it a vapour barrier. I guess I'll double check on that though. There are a few things I've found in building science articles that code is in contradiction too. If anyone is aware that I am mistaken (Ontario), please correct me!

I'm thinking I might just get the window replaced, and then have it jammed out to the proper depth. Save myself adding two layers of drywall... The window is old anyhow. It's functional, so I'd rather not as it's not really in the budget at the moment, and I'd rather do multiple windows at once, but hey.... might as well complete the room.

On the side with the door (interior wall), I'm just going to go with my 3/8 spacers I made.
