Egress Window 5.7 square feet casement

Yup, it looks like there's a law that 2nd story residential bedroom windows have to have a total opening area of at least 5.7 square feet (there's a rule about allowable ranges for width and height also, and a rule about maximum height from the floor (so that kids can get out the window if they need to, apparently). With all that, you have to know what to look for in the window catalogs to make sure that you're getting one that meets the requirements. Here are some links:

Here's a forum post by somebody else who got bit by this. He wonders at the unfairness that this rule delivers to somebody who wants to use double-hung (freaking wide windows). From this, somebody responded that you can get casement windows that look like double hung.

By the way, what's with all the great building information on something called gardenweb?

Here's a forum thread where some newbie asks all the right dumb questions in the right order, and the whole process is laid out cleanly in the answers that the pros are providing. There's a link to the Andersen catalog, a mention that their model numbers with X meet egress code, and a link to a Pella catalog.

Anderson has this uncharitable egress opening calculator:

This question about smallest casement egress windows with trim does not really get answered well, except for the suggestion to skip trim:

Here's the Andersen catalog. For some reason the X sizes don't look like the right window:

Picasa Photos Missing

Picasa seems to be a poorly written piece of software; it's a shame that it's one of the few that nonetheless has exactly the type of photo tagging UI that I need.

The point of Picasa is that it keeps a database of all the photos on your computer, and you can create copies or tags using the database. Too bad the database fails a lot.

Basically, if you install Picasa and tell it to (or let it) find all the photos on your hard drive, the ingest process will choke, huge numbers of photos won't be ingested into the database, and there is no way to fix the database other than uninstall Picasa and reinstall it.

I did a gigantic search where I found people posting over and over again that this bitter conclusion is the only option. It was a while ago so I lost most of my open tabs. Here are a couple of links but not necessarily the best ones.

http://picasatutorials.com/2010/04/albums-vs-tags/

http://64.233.163.104/support/forum/p/Picasa/thread?tid=1e8d137ce6dd8b04&hl=en

In order to prevent the ingest tool from fucking itself up, you have to completely uninstall Picasa, reinstall it, and don't let it try to find all the photos on your hard drive. Then once the install process is complete, use to select very small sections of your photo folders and ingest them, letting it finish each time. Doing this will produce a complete ingest and things go a little better from there.

Drain Tile Through The Wall

I am having to lie in my own bed with this drain tile, but I think that in the end it might still work out.

The first question is whether to bring the pipe in through the wall at its current height or try to dig down and find the existing drain tile or some other solution. I think the answer is still to bring it through the at height. Digging down to the drain tile seems like it won't help because from the earlier excavation it seems like it could be just anywhere, plus there's no guarantee that it goes to the sump any more.

The second question is the size of pipe to bring through. I still really like the idea of bringing a 3" pipe through, even though that's going to stress out my wall, particularly if I have to sheath it, and even though I'm immediately knocking it down to a 2" pipe once it comes through so that I can put the valve on it.

The third question is at what height to bring it through. The test drilling really hinted that I shouldn't go lower than that one mortar seam.

The last question is how to bring it through without either creating a huge leak or ruining the resale value of the house. It appears that pipes of this sort are sealed with a variety of sealants, but the polyurothane is the preferred solution at present. Other options are cement (buh), epoxy, and tar. I can get epoxy and tar at the local big box hardware store, the PE will be mail order and spendy.

Links:

Ask The Builder dispells the idea that the black tar on the foundation wall is good for "waterproofing", and talks a bit about epoxies and urothanes:

Here's somebody selling a product by dishing dirt on the epoxy solution. Actually, this goes through all the different systems and was a pretty good tour of the options:

Here's Ask The Builder's typically specifics-free report on epoxies:

Interestingly, the Wikipedia article has some info on polymer repair glues:

The range hood roof vent.

Home D has this bitching 4" one:

http://www.homedepot.com/buy/building-materials-heating-venting-cooling-hvac-parts-accessories/master-flow-4-in-goose-neck-vent-in-aluminum-132939.html

It appears that MasterFlow is really a company named GAF? They make this one (It is part number GNV4A) which I found elsewhere on the GAF web site. But this site is for all of the other "goose neck roof vents". A regular goose neck range vent looks inappropriate for a residential roof though.

http://www.gaf.com/Roofing/Residential/Products/Roof-Vents/MasterFlow-Chimney-Roof-Caps-Accessories/MasterFlow-Chimney-Roof-Caps-Accessories.aspx

Also, HomeD will sell a GNV6 if I really wanted one:

http://www.homedepot.com/buy/building-materials-heating-venting-cooling-hvac-parts-accessories/master-flow-6-in-goose-neck-vent-164902.html

Somehow, I blundered into the model I want, except offered by Lowes' and it's from BROAN:

Insulation for 6" roof joists

Ain't no way that I'm going to be able to stuff R-38 into the sections where the old roof joins the new, and it will probably get a ding from the inspector unless I address it, so what to do?

My findings so far:

There's a term "High Density Insulation". It seems to apply to blown insulation though. Here's an installation guide for "Dense Pack Cellulose" from a state government:

http://www.incap.org/fieldguide/6%20-%20Insulation.pdf

Certainteed sells something called "High Performance" batts, which look a lot like regular insulation to me. It's supposed to be better, but not enough better according to the chart in the specifications sheet (2nd link).

http://www.certainteed.com/products/insulation/index/317362

http://www.certainteed.com/resources/30211239.pdf

You'd think that styrofoam board would be pretty good, but they only make it up to 4 inches thick, and even if layered it wouldn't quite make it up to R-38:

http://building.dow.com/na/en/products/insulation/deckmate.htm

Here is an unbelievably good guide to the different insulation options, which is my first lead to PolyIso types:

http://www.insulation-guide.com/insulation-types.html

Here's a forum with one answer that also points to polyiso. Note that he claims R=7/inch, so with 5.5" and no ventilation baffle, I cold get R38.5!

http://www.doityourself.com/forum/archive/index.php/t-387868.html

Ok, this is just interesting. I'm sure there's something in this dense blog post about different ways to add R-values. He references the wikipedia article which I found is too general and lacking the kind of dumb table that I'd like to see.

http://sites.google.com/site/phillipnormanatticaccess/Home/insulation-math

Here's an installation manual from something called NRCA. This is interesting because of learning about the existence of NRCA, and that it says to consider polyiso as having a R value of only 5.6/inch and to ignore the manufacturer's Long Term Thermal Resistance rating. It would be sad if true.

http://www.nrca.net/rp/technical/manual/06pdfs/99_100.pdf

Here's a company that makes polyiso. They have a distributor in Baltimore:

http://www.atlasroofing.com/general2.php?section_url=2

Certainteed makes a polyiso that they call FlintBoard, which seems to be commercial oriented. There are further hints that this stuff is intended to be the top deck of the roof rather than under-mounted.:

http://products.construction.com/manufacturer/certainteed-roofing-----low---slope-nst18285/products/flintboard-polyisocyanurate-roof-insulation-nst5378-p

http://www.certainteed.com/products/roofing/308322

Here's a nice web site that is a bit more optimistic about polyiso without providing too many details. They also go into the dual nature of preformed vs. sprayed for this material.

http://www.energysavers.gov/your_home/insulation_airsealing/index.cfm/mytopic=11620

Here is a bulletin from PIMA that primarily seems to be oriented towards commercial roofs. But it is interesting to know about the existence of PIMA.

http://www.pima.org/BulletinFiles/tb113_clr.pdf

http://www.pima.org/contentpage/Faq.aspx

Here they talk about muliti-layering polyiso:

Here's a cute little TOH article that mentions it (with very little details):

http://www.thisoldhouse.com/toh/article/0,,1575422-6,00.html

Here's an article about cape cods. The big panels are nailed on top of the roof in the photos:

http://www.deerparkroofing.com/insulating-ventilating-cape-code-house.php

Here's a TOH article about foam panel. Way down near the bottom, it talks about installing the foam outside of the wall. It does discuss spray-on near the middle.
