You have to make sure that at least one corner is square in and of itself, too, or make sure that the walls are the same lengths. You just have to make sure your sides are the correct length. If the opposite sides of any square or rectangle are equal length and the corner to corner is equal, there is no possible way it's a trapezoid. Measuring one corner for squareness assumes the sides are the correct length anyway. The two sides opposite the corner measured could be the wrong length and unsquare to anything, but still get a correct length corner to corner.

One 90 degree corner, Two 89 degree corners and one 92 degree corner would be an example. EDIT: ^^ What he said.

http://imgur.com/cG7uxeP How bout that crack? This used to be a gun store. Rumor is the city was going to eminent domain the building and tear it down. City bought the building and then it was found to be some sort of historic building and now several years later it still stands with the city unable to do anything.

Baronjutter posted:I live in a 70 year old apartment building. I took one of the bedrooms to become my "train room" to build a big ol' train set in and drew up all the plans to use the space efficiently. I soon learned the walls vary by almost 2" from the front to the back, and the floor slopes about an inch from the walls to the centre. Old buildings! Old hah. Back in 2000 I was down in Orlando working for Bellsouth to install cellular gear in those little sheds under towers. We got assigned to a location one day on the 7th floor of a hotel down near Disney. It was just a gutted hotel room turned into an equipment space, standard procedure of putting in the equipment was levelling everything before anchoring the cabinets down. Along the way we discovered the floor dropped over 3 inches just in the space of 6 or 7 side to side equipment cabinets. It was so bad we could barely get the equipment level, the adjusting feet on the bottoms were maxed out on one end, and max screwed in on the other. loving loony-tunes setup. Then we got yelled at by our boss for not bracing the cabinets up to the cable racks. Apparently he couldn't understand the concept of "There is literally one and a half inches of space, and the brackets are three inches."

This article (PDF link) is interesting; it talks about designing a house with unusually thorough insulation (R-80 attic, R-60 walls) and other energy-conserving designs. The walls are 16" thick!

The walls are 16" thick! That article is 15 years out of date. These days you could get similar results in a much smaller space by using foil-faced polyiso under the sheathing and closed-cell spray foam in the bays. Like you could probably get the walls down to 8" total.

The only thing out of date about that wall assembly is the 6 mil poly vapor barrier. And going overboard, 12" R-40 walls are more popular. Closed cell spray foam, particularly filling stud bays, is not particularly popular in super insulated homes. It uses a high GWP blowing agent, used within stud bays its high r-value is severely compromised by thermal bridging from the studs, it has far less air sealing benefits than commonly believed both because many of the critical air sealing aren't within stud bays and because seasonal expansion and contraction can cause it to separate from wall studs, and of course, it's expensive. Polyiso is a poor choice for exterior sheathing anywhere cold enough to justify an R-40 or R-60 wall. Most insulations perform better in cold weather, but polyiso actually starts performing worse once it drops below about 50F (because the blowing agent condenses); by the time the temperature has dropped below freezing even EPS foam has a higher R-value. Foil faced polyiso is particularly unpopular because the foil is a vapor barrier, which prevents any outward drying of the sheathing; sheathing sandwiched between ccSPF and foil faced poly iso would have no drying potential and would be damaged by any moisture intrusion. The most popular super insulated wall assemblies are double stud walls filled with cellulose or open cell spray foam, or a standard 2x6 24" OC stud wall with cellulose in the bays and 3-6 inches of rigid foam on the exterior (although rigid mineral wool seems to be quickly gaining popularity).

I have been woefully misinformed about polyiso, apparently. I knew closed-cell was a) expensive and b) not as fantastic at being a vapor barrier as actual vapor barriers. But isn't thermal bridging an issue with any in-bay insulation? I thought rigid foam on the exterior was used partly to deal with that thermal bridging regardless of the in-wall insulation (batt, cellulose, spray foam, etc.).

Closed cell spray foam is a fine vapor barrier, it's just a mediocre air barrier (within stud bays). An air barrier needs to be continuous; any hole or gap will allow air through when there is a pressure difference (exponentially as pressure increases), so even small flaws can let through a significant amount of air. A vapor barrier stops diffusion, and diffusion is linear with surface area; holes and gaps only matter in the proportion to the total size; a 95% complete vapor barrier stops 95% of the vapor diffusion. (I should note that closed cell spray foam is quite popular for rim joist insulation, where the vapor barrier can be important, and bridging the spray foam across bays does make for an effective air barrier) Thermal bridging is indeed a concern with any in bay insulation; it means you get diminishing returns in the total wall R-value as you increase the R-value of the bay fill, so spending a lot of money for a higher r-value within the bay has a pretty poor ROI. Cellulose is popular since it's relatively cheap, it's generally considered "green", and resists air flow well enough to both reduce the impact of flaws in the air barrier and avoid the many problems fiberglass batts face with convection (and also gaps around obstructions). Edit: oh, and also cellulose is hygroscopic and can serve as a hygric buffer, adding a bit more moisture resilience to the assembly (or a lot, if you ask the cellulose manufacturers).

Why two stoves, and why not opt for front facing controls? Who needs two microwaves, and why not at least make them look like they belong? Instead of using an overhead microwave he built a very poorly measured shelf for a countertop unit. The island that serves solely to create an obstacle between the sink and the rest of the areas of the kitchen. After sinking 60 grand in a kitchen you shouldn't have to leave your appliances on a windowsill.

Sorry to double post, but I should stress that the guy is not a big fan of realtors. If your friends have a working relationship with theirs I don't recommend putting them both in the same place at the same time if you can avoid it. I don't think my realtor (who we actually trust and have a good relationship with) was too impressed with some of his "all realtors are out to get you and you don't need one" comments. oh god please don't start a realtor derail

Given poo poo's propensity to both float and sink, a reasonable estimate of density would be 1.0g/cm^3, or the same density as water. Since a gallon is equal to 3.78 litres, a gallon of poo poo would therefore weight 3.78kg, or 8.3lbs.
