Ok, I am going to thoroughly expose my lack of knowledge with this question (no claims to any expertise on my part), but I'm hoping that some of the experts here can comment on something I am thinking about.

I am installing new windows and cement board siding. We are adding an inch of foam board to the exterior. I know the siding can be nailed through the foam board into the sheathing by extending the length of the fastener, but can the same be said about nailing the window (flange) through the foam board? I realize that I have either that option or the option of building out my frame by an inch with OSB or ply so that I get a solid nailing surface. Is there a preference?

Since a SIP is basically like an I-beam type of setup, it relies heavily on the EPS foam core for its strength. The downside is that EPS begins to melt around 165F - 180F. Once the foam fails, the structure fails/collapses.

Has anyone observed or read about a SIP roof or SIP wall home being involved in a fire? If so, what was the outcome?

What's the hottest temperature that a SIP roof can get? I assume in the desert southwest a SIP with a metal roof on top can see some high temps. Is it hot enough to melt the EPS core?

Thanks for any suggesWhat is a good old bathroom exterior wall progression method (1947 home in Edmonton, Alberta) ?

From outside to inside: cedar siding, then 2X6 Douglas Fir planks, 12" studs.

What would be a good insulation choice?

What would be a good baker board choice?

What would be a good drywall choice?

Should a vapor barrier be used?

Will also be installing a bathroom fan- horizontal exhausting through exterior wall due to possible vermiculite/asbestos in attic. What would be the specs for this? It is difficult to find information for this unusual location.

Hello everybody. First post -- just signed up. Great site. I live 30 minutes north of the Twin Cities and I'm looking at building a passiv type haus. I've found the land I'm building on (10 acres) and have somewhat of a plan for the building.

My wife and I want to build a barndominium. Looking at 50x70 total with 30x50 two stories and 40x50 shop. I have a general idea of how I want to build but alas I am newb and was hoping for some insight with the pros on this site.

Thanks again and any advice would be greatly appreciated.

Hi,

We are currently restoring a Usonian style house built in 1962 here in Northern Illinois. The sunroom is currently being restored to its original design with a few exceptions:

How tight does a house need to be at ACH 50, before an ERV or HRV is recommended?

I have a humidistat sitting in my house the last few years, and have taken notice of the RH%.

I am concerned that an HRV will dry out my house too much. Location is Toronto which has cold winters (down to -18 celcius) and summers up to 30 and 35 celcius humid

With a forced air system with a humidifier installed, we go down to about 16% humidity in the winter on the coldest days. typical is around 20%-24% . In the summer we are at about 50-54% ish.

with these numbers would an HRV make it too dry, or would the numbers typically be affected only slightly?
