Much Ado About Spray Foam

This is what my living room looked like a few hours ago.

This is what it looks like right meow.

What you are looking at is a little over $500 worth of spray foam. Expensive? Very. I’d like to think I’m worth it though. Once again I used our touch n seal cpds closed cell foam. It was cold, and I had limited time, so I didn’t get the optimal expansion, but it turned out okay. I sprayed around 2 inches,  giving me an air tight, moisture proof r14. I could have filled the entire cavity, but opted not to for cost reasons. I’ll be picking up some drywall later and throwing that on.

I had an opportunity earlier this week to use another type of closed cell spray foam so I figured I would share my experience. What I used was Dow chemicals refillable set up. I’ll start with what I liked about it first. The cost per board foot of dow’s chemicals is cheaper than what we are paying right now, the applicator gun feels more expensive and does a better job at keeping a 1 to 1 ratio, the tanks are larger so there is less down time swapping out product, and they had a much longer hose reach.

Now, the negative. Instead of an air compressor with a doubler like our machine has, it uses a nitrogen bottle as it’s propellant. Setting and maintaining equal pressures in each tank was kind of a hassle. The tanks are refillable, which means that there is the possibility of some jack ass pounding to much product into a tank at one time and creating excess moisture in the tanks. The problem with moisture is that it makes the chemicals crystallize and not mix properly and clog up the system. Finally, it seemed like there were more air voids in their foam than ours. Granted, the foam was a few months old, but it just didn’t seem as rigid as what we are applying.

All in all though, I wouldn’t have an issue with using either product but give a slight edge to our touch n seal based on my familiarity with it.

Windows ME

If you’re a nerd you’ll get the joke in my title. If you don’t get it, congratulations, you probably have friends. Regardless, I put some new windows in. 6 foot wide by 4 foot tall. The old widows were 5’5″ by 5’5″. I am not a fan of windows being close to the floor. I like having them above average groin height (which I’ve found to be three foot tall). The reasons for this are simple: 1, if you wake up hung over and have no pants on, you can’t be called in and wind up on the registered sex offenders list and 2, if you are drunk and fall over you won’t be as likely to fall completely through your window. Now I know this place will never have a huge resale value do to it’s limited square footage so I went with cheaper vinyl windows.  Something interesting about windows is that there are only a few companies that make the actual glass. What you are paying for is whatever companies hardware that surrounds the glass. So if you need some new windows, and can only afford the cheap vinyls and not the fiberglass or wood framed ones, don’t worry about it. You’re still  getting a high quality well insulated window, it’s just wrapped in a not gorgeous looking piece of plastic. If you’re not  completely lazy you should be framing out the windows with pine boards anyways, so the finished project shouldn’t look like a crappy apartment. Having said all of that, here is a picture of the new windows.

I later removed the window to the right and currently have it all boxed in. Tonight I was having fun in my crawlspace pulling wiring. I should have all of the wiring and insulation done for the weekend and then it’s drywall time again.
