Final Countdown, will 2" Foam be worth it for me?

Hello all!

I have been asking questions and researching energy efficiency for the past two years. Finally I am getting around to building my own home and will be installing, or not installing, rigid foam in the next couple weeks!

My house build is financed mostly by a construction loan.

  • I have calculated $2,380 in the cost of rigid foam
  • $160 in material to bump out window and door openings 2"
  • $80-$160 in Aluminum
  • $300-$500 for labor to get Aluminum fabricated for the bottom
  • $40 in cap nails

How to hire a tiling contractor?

Hello,

The two local well known tile person are both tied up and can't work on our house since the builder didn't line them up when he should have.

I am in the process of interviewing the tile guys and was wondering what do I need to ask them to see if they know what they are doing?

secondly, also when I go look at their work, what am I suppose to be looking at?

Thirdly, any important tips that I need to know/ask the tile guy for laying down marble/Limestone tiles on the floor and regular tiles in the shower?

We were looking to replace our front door which has 2 flanking sidelights

The door appears original to the house which was built in late 1890s (all glass is single-pane and the door has no weatherstripping). Needless to say, it's very drafty (we use rope caulk to seal gaps and plastic to cover windows in winter).

We've had 3 estimates for the work, all ranging between $3,000-$5,000 bucks. All contractors cite unknown condition of framing, subfloor, etc.

Feedback on 2 X 8 exterior walls w/2 X 4 studs in the bays to limit bridging. Cellulose ins.

I live in Eastern Washington, Zone 5 A. 100 degrees in the summer to zero in winter with 1-3 ft of snow. I will hopefully be building a home this summer, 2016. I originally looked at SIPs but am convinced that if they are not installed perfectly I may end up with moisture problems later on. My brother suggested 2 X 8 top and bottom plates with 2 X 4 studs, (1/2 inch gap between them to break the thermal bridging), and blown cellulose insulation. Then two separate pieces of 1 inch ridgid foam insulation on the outside.

Question about insulating foundation Superior Walls

Hello,
We are planning our new home in Illinois (border of Zone 4 and Zone 5). The entire exterior will be EIFS. The majority of the basement will be finished. The east wall of the basement will be a walkout, which we plan to have wood-framed. We plan to use the Xi Superior Insulation walls for our foundation, which adds 2.5" of Dow Styrofoam to the original Superior Walls for R-12.5. Here's a note from their website about the walls:

Flogging the half dead vapor barrier horse…

At the risk of being heaped with much deserved abuse I have a yet more vapor barrier questions.

I am in the process of designing my new home and have settled on a double stud wall construction with a load bearing inner shear wall, a sheathed 2x3 framed outer wall and dense cellulose insulation.

Insulating a wall that is exterior on 2nd floor, interior on 1st.

I hope the topic of this question is understandable. Imagine a floor plan that is a simple 2-story box (ie, 40x40) that has a single-story wing to one side. The common wall between the main structure and the wing will be both an interior (1st floor) and exterior wall (2nd).

Pretty Good House in Iowa

I am planning on building a "pretty good house" in the MidWest (Des Moines). After throwing around ideas on different wall structures (double stud, 2x6 with wet blown cellulose and rigid foam exterior), I'm curious what the prevailing thoughts are on building a 2x4 wall (16" o.c.) with 1/2" exterior plywood sheathing. 2" rigid EPS would go exterior, with WRB being Tyvek, then furring strips and hardi-plank siding.

Insulation for 1:12 standing seam metal roof

Hello all,
Newbie to GBA but we are interested in building an efficient home. We live on the edge of zones 4 and 5 in Illinois. 100% of the exterior will be EIFS. The plan is for our exterior walls to be 2x6 with cellulose in the cavity and rigid foam over the sheathing.

My question is about how to ventilate our standing seam metal roof (1:12 pitch). Our architect didn't seem to have a good grasp on green building techniques.

My questions to architect:

How much energy does the evaporator coil waste?

While working through Manual D calculations I was surprised at how much of the total static pressure from a blower motor is dropped through the air conditioning evaporator coil. In my case I had a drop of .3 iwc at the coil for a total external static pressure of .7 iwc at 990 cfm. That's almost half of the blower load being used to push air through a coil that in my climate (zone 5) is just in the way most of the year.
