Toughest vapor barrier for floor of crawl space?

We're building a new house, and plan to create a sealed conditioned crawl space. We want to be able to access the space regularly, to inspect for leaks and store a few items. Which vapor barrier would be better able to hold up to regular traffic? We'll probably put a layer of coarse sand underneath it. Unfortunately, a concrete rat slab is out of our budget.

Insulating basement foundation


I have read a lot on GBA and a few other trusted resources online and am still not clear. I have an unfinished basement below grade in zone 4 (Minnesota). House was built in 2015. Builder sprayed a black coating on the poured concrete foundation and then applied a 1.5"-2" thick rigid foam insulation to the exterior of the foundation before backfilling (completely below grade basement).

Best way to plumb for outdoor shower (with hot water)?

Hi guys,

I am wanting to have an exterior hose bib that allows for hot water, so I can hook a shower up to it.

Because I am in a tiny house on wheels, my walls are only 2x4. The only product I have found is woodford hot/cold bib

Unfortunately, even for the 2x4 model, it's 5 7/8" long. So this product would stick out on the interior side.

It's also important to note that my one piece corner shower will be on the same wall, so there is no room to come out on the interior side.

Cut and cobble - basement ideas?

Hello all,

I'm located in western Washington, zone 4 marine, and we're working on our early 1970s split level. When we purchased the home last year we ended up needing to put in a sump pump and interior footer drain. Since then, we've been monitoring the walls and relative humidity. There's been no new evidence of moisture and later this month we'll be installing a new heat pump and plan to use the dehumidifier function.

Z-girt, insulation board, and metal siding

I'm building a cabin out of Faswall hybrid ICF blocks and plan on adding an additional 3" of Roxul Comfortboard on the outside wall before installing metal siding. I had planned on using one layer of 1.5" Roxul then screwing 2x4 furring strips in place with an additional 1.5" of Roxul in between the furring. But wouldn't it be more efficient to just use metal z-girt strips with a 3" web to support both the Roxul and to mount the siding to?

Insulating a house (remodeling project)

Some background information:

Zone - 5A - Shoreline Connecticut
Construction Year - 1958
House is framed with 2x4" studs, sheathing is 3/4" tongue-and-groove.

I've begun remodeling and I'm currently at the point where I'm ready to re-insulate my master bedroom. My plan is to attack one room at a time and the first is always the most difficult, so anything I do in this room I plan to transition into the other rooms (more-or-less).

My question is, what is the best approach to tackling this project?

Easiest way to frame interior walls on slab

I am building a house with double wall construction. Exterior 2x6 wall is framed. It is a slab on grade home and there is some unevenness in the floor. Trusses will be delivered soon and I worry about having interior non-bearing walls sticking up too high and causing problems for trusses that are designed to span from exterior to interior bearing walls.

Should I:
1) Frame all the interior walls a bit shorter and frame interior walls before setting trusses

I am researching the capability of a 40-gallon electric hot water tank

If water is tested at 2 AM and it takes 3 mins to reach 143 degrees (no one used any water for the previous 9 hours) temperature outside is 62 degrees and someone used the water at 2 pm (washer, dishwasher being used) temperature outside is 89 degrees, would it still take 3 mins to reach 143 degrees?

Gable access to attic?

The house we are designing will have an attic with roof trusses. No ductwork in it, just lots of insulation. The only time I think it would need to be accessed would be to check for or repair roof leaks. Properly air sealing and insulating an indoor attic access hatch seems somewhat expensive.

Does anyone access their attic through an exterior door in the gable wall - where it would need to be weatherproof, but not air-tight or insulated? Not sure if that is feasible or practical.
