Filling nail holes in Zip?

I have a question. Framing almost done. Have exterior sheathing done with Zip board.

I noticed that the framers' guns' pressure was high, and nails in some areas went deep into Zip, or in some areas nails missed the studs.

Question: Does it make sense to try to fill deep shot nails with a liquid barrier of some type?

If yes, what type?

I was also thinking of putting a stapled or peel-and-stick weather barrier over the Zip instead. Does that make any sense?

Ipe wood vs. Azek (PVC) decking

My cedar deck has rotted. Periodic sanding & staining extended its life but now it is over. I am considering using either ipe wood or a PVC decking material (brand Azek). From the little I know, trying to consider a life-cycle assessment, neither seems like a great environmental alternative. Is there a clear choice between the 2?

Insulating a wall that is half plaster/half drywall?

We live in a home that was built around 1920 near Chicago, IL. Our plot is narrow and the front portion of the home is the original house, with a very large addition on the back from the previous owners (2007). The staircase in the old house was sloping heavily to the right. We had a structural engineer come take a look and he attributed it to natural settling and didn't see any signs of continuing movement and didn't make any recommendations aside from sistering one joist. I'm not a master carpenter, but I have built a staircase or two in my life.

Daylight basement insulation - exposed XPS and other questions


I’m about to insulate the floor and 2 walls of my walkout/daylight basement, and I was hoping to get a little advice on a couple of points I’m not clear on. I’ve researched quite a lot, and learned a lot on this site, but I’m still not sure on a few things. Any help is much appreciated.

What is wrong with my gas fireplace?

We have a gas fireplace insert. It will not stay on if the solid glass door is on it. If we remove the glass it will work. We've had a partial inspection done on the control and logs. They seem to think it is not getting proper air ventilation. Would this be due to improper install of liner? would they be something clogging up the liner?
Any thoughts would be appreciated. Our chimney is approximately 40 ft. so we are having a hard time finding someone to look at it.

Frost on outside of triple pane window

Every so often I notice frost/water (depending on outside temp) developing on the outside pane of my triple pane windows. It's infrequent but will mostly notice it early mornings. Actually, as I sit here this evening (68F indoors, 28F outdoors) the exterior of my windows are frosting up a bit. Interior pane is warm to touch. No moisture problems inside. Air exchange keeps interior moisture around 35-40% in the winter. Moisture (minimal-in bottom corners) only forms on interior windows when it's -10F and below. Thoughts? Thanks.

Whether or not to insulate open joist bays between 1st and 2nd floors .

So far Erik North’s Free Energy Maine blog/website has been the only site that actually answers the question about whether or not to insulate open joist bays between 1st and 2nd floors on his blog post “Should I Insulate Between Floors?”. I tried posting a comment on the blog page looking to get his suggestions what is the way best resolve this issue, but it doesn’t go through.

His site led me to the Green Building Advisor webpage, so I am hoping that someone here would be able to provide me with some helpful advice.

Ductless HVAC and humidity control?

We live in Pensacola, Florida and area with extremely high humidity. We are building a new house which is about 2800 sq ft. House consists of a main floor at about 1800 sq ft, second floor at about 800 sq ft and a loft at about 200 sq ft. The current plan is to go with an all ductless Mitsubishi HVAC system, well actually 2 systems. 1 controlling the first floor and a 2nd for the 2nd floor and loft. We have a very competent local installer and I have zero doubts about their capabilities and the pricing I feel is fair.
