That Warm Fuzzy Feeling

We're getting the house insulated. This ia big step in the direction of energy efficiency (Thank you, President Obama, and your tax-credit program!) and staying warm during the winter months.

We're going with cellulose insulation because it's an old house, foam is toxic, and fiberglass is too pink, but mostly because the dispelled cellulose myths are hilarious:

Sprayed foam insulations can be green, too.

Sorry, no way. The only thing green about sprayed foams is the money you pay for them. Sprayed foam insulations are made with petroleum and petroleum byproducts, and that just isn't green.

What about soy based foams?

Sorry, not green. First, they're not soy 'based' - they contain a small amount of soy additive. While soy added to foam does save a little bit of oil or chemicals, the soy had to be grown, watered, fertilized, harvested, trucked, processed - well, you get the idea. Foams with soy additive are heavily marketed for their soy content, which is something called 'greenwashing'.

Unlike cellulose, foam insulations air seal and insulate at the same time

They can, certainly. But we have a lot of experience inspecting structures in the field that says that foams, especially the more rigid foams, don't have the flexibility to move as the structure does. That means there can be separations between the foam and the framing members as the lumber dries, shrinks and moves, which can allow air infiltration. In addition, there are areas that aren't routinely foamed, like the junction of a wall's bottom plate with the floor, or top plate with upper story framing and flooring. The bottom line is that proper installation of any insulation should include air sealing.

I just want my insulation to do a good job insulating

Of course you want your insulation choice to do a good job insulating. But to do that, it has to do a lot of things - effectively prevent air infiltration, manage moisture, etc. And you don't want it to create problems - make a good home for pests, outgas, etc. And then there are things you want it to do that you might not associate with an insulation product, like make your home safer in the event of a fire, do the best job of reducing noise, and have the least impact possible on the environment.

National Fiber's Cel-Pak and Nu-Wool insulations do a great job at all the things a great insulation should do, with none of the potential downsides.

I just need to insulate my attic, so can I do it myself?

Well, you can - but that doesn't mean you should. There is a proper way to install cellulose, and lots of ways that aren't. A proper loose-blown attic job will be inspected for problems, may have old insulation removed, have the soffits blocked off, have air-sealing done - you get the picture. There's more to it than just renting the machine and blowing the cellulose. (And lots of those big box cellulose products aren't as clean as National Fiber's, and many have ammonium sulfate in them - see 'Cellulose produces funny smells', above) Besides, don't you have better things to do with your weekend?

Do yourself a favor - locate a qualified installer and have the job done right.

"Of course insulation should insulate, you idiot! Thank goodness you came to our website, we spend all day trying to educate ignorant bums like you!"

Being funny is certainly better than being the method of harvesting marijuana.

Down And Out And Napping

They turn off the air conditioning in the office at jsut about 3 o'clock everyday.

Paired with the ridiculously nice weather today this is a recipe for disaster.

And by "disaster" I mean "a nap."

So I have effectively shut down for the day (for the weekend? for the rest of the quarter?). Or at least until I have a reason to move. (all year?)

Next week: more posting! (hahaha, I am hilarious)

Ramblings Insane Ramblings

In the last ten minutes work has slowed dramatically. In order to still appear as a productive member of the staff I've opened a text message window where I will be narrating a portion of the day.

I am currently looking out over the cubicles on the floor and am noticing that the majority of the guys in this office have recently had their hair cut.

I ordered sunglasses yesterday, finally pulling the trigger on the expenditure after being both eager (for new shades) and reluctant (to pay the asking price) for some time. They should arrive after a few short weeks during which the manufacturers will, no doubt, be selecting individual grains of volcanic silica suitable for melting into UV-resistant shaded glass; mining and separating aluminum ore from the dangerous and exotic caves beneath Machu Pichu (the only known, terrestrial, source of eyeglass-frame-grade aluminum ore); and grinding the volcanic lenses to my exactingly unique specifications.

I am also drinking the world's largest coffee, the Starbucks Venti. Peace! I am aware that the verysame Starbucks has announced the "Trenta," and, at 31 oz. you're hollering at me now that the Venti is only second in the world of giant coffees. Let me reassure you. The Trenta is, in fact, the world's largest coffee *cup* but not in fact the world's largest coffee, as the Starbukiristanians must in fact pour a Venti, and then a little bit more, in order to fill it. The scientists among you are cognizant of this fact, and I repeat it here for my none-sciencey readers, "It is physically impossible to pour a coffee larger than 23 oz."

I am currently reading a Mary Shelley classic, "Frankenstein" on a decidedly non-classic e-book for the iPod Touch.

I am not blown away by the story so far. Stoker's "Dracula" was much better.

Halfway through my coffee and it has become apparent that caffeine does not aid my concentration in any way. So I'm posting this now, if for no other reason than to increase the spam comment count here and prove (to myself, anyway) that blogging has not been beaten, murdered, and replaced by micro-blogging. (But we all really know that it has. I blame the whale.)
