Water condensing between vapor barrier and Kraft Facing

Leave a comment

By mwalkowi

I’m in the process of framing up a couple of bedrooms in my basement, slowly but surely. Previously, I started with bare concrete walls with 2×2 fir strips running vertically, spaced 24″ apart. Between the strips I placed R13 fiberglass batt insulation with the Kraft facing (this stuff: “Owens Corning EcoTouch Kraft 3-1/2 in. x 23 in. x 93 in. R-13 Batts in Bag Insulation”). On top of the Kraft paper, I applied a plastic vapor barrier stapled to the fir strips and the joists above.

Last weekend I noticed a couple of places where water looks to have condensed in the space between the Kraft paper and the vapor barrier. I pulled the vapor barrier away, then inspected the insulation – it was completely dry (except for the spot on the Kraft paper). The block behind the insulation was completely dry as well.

Our theory is that with the high due point the last couple of weeks, moist air found its way behind the vapor barrier and decided to condense between the VB and the Kraft paper.

My question is, should I be putting a vapor barrier over the Kraft facing (which I understand is a vapor retarder in and of itself)? Is it a no-no to place a vapor barrier over the top of the Kraft facing (having two vapor barriers touching)? And if it’s recommended/required to have a plastic vapor barrier on top of the Kraft, what is the recommended way to prevent water vapor from getting behind the vapor barrier?

Or maybe I just need to look harder for the source of water getting into my basement from the outside?

Thank you!

Starting with C-Programming

Leave a comment

By Dr. Nick

Hello guys!

It’s been some time and I have been busy. I got my qualification as an IT-Professional now (Systems Administrator).

I learned VB.NET at school but I don’t want to continue using that language, I want to learn C because I’m working with Linux/UNIX most of the time, also I do electronics and will get a Arduino soon.

I learned VB.NET (basics) the “school” way. Like how to programm a class or how the syntax of a while-loop is. I heard Richard Stallman say that you should obtain some open-source software and “expand it” by adding code or changing the software to fit your needs. I mean, after 1 year VB.NET I must say I can’t use the language properly, that gets me thinking.

I already got a book about C (Galileo Computing, german site) which reads pretty well, I’ve been working with that.
I think that if you work hard enough, you can always reach a goal. I just want to go in the right direction from the start because I don’t want to waste any time.

So here are my questions:

1. What’s the best way to get started? Should I look for a projekt to programm (maybe from Rosetta Code) and start at that or should I go through C step-by-step like:
1. Data-Types
2. printf
3. scanf
4. while
5. for
…

2. How did you get started?
3. Are there any sites/books/youtube videos that you can recommend me?

greetings,

nick.

Jorge Castro: Vagrant Ubuntu images now available.

Leave a comment

Just in case you missed it we now have soon-to-be official Vagrant Ubuntu cloud images thanks to Ben Howard.

Never used Vagrant before? Check out these slides to get up to speed:

Here’s the TL;DR;

sudo apt-get install vagrant
vagrant box add myprecisevm http://cloud-images.ubuntu.com/vagrant/precise/current/precise-server-cloudimg-amd64-vagrant-disk1.box
vagrant init myprecisevm
vagrant up 
vagrant ssh

This will install Vagrant, get the 12.04 image, and set it up as a VM with as “myprecisevm”. There’s no need to download and configure virtualbox seperately, the package handles that for you and vagrant itself makes it so you don’t need to deal with VB directly.

While that is downloading, make sure you check out the Vagrant Getting Started.
