Insulation and Ductwork Insulation
Man, I hate insulation!!! But, you’ve got to have it. General home insulation and ductwork insulation is a real good way to keep saving money over the years. I will only talk about rolled fiberglass insulation because it’s the only kind I know about. It’s also the most cost efficient.
You will have different thickness options. Some are pretty much standard for instance, if you build your walls with 2X4’s then you’ll only be able to use R-11 or R-13. That is the thickness of a 2X4.
If you build walls with 2X6’s, then you’ll be able to use R-19, which is the thickness of a 2X6. Most modern homes are built with 2X6 walls, not so much for strength, but more for energy efficiency.
The importance of floor insulation and ductwork insulation is almost always underestimated.
You should try to make energy efficient walls by putting in R-19 if possible.
Make sure you get insulation everywhere. Be sure to put it behind outlet boxes and inside headers. Sometimes these are left out and they loose heat.
One of the biggest heat losses is in ductwork insulation. With the new ductwork wraps available, you can can save a bunch of money on heating and cooling.
The duct wrap just wraps around the air ducts and some people even wrap water heaters. Water heaters are already insulated pretty good, but if it’s in a drafty location then definitely wrap it up.

I just wanted to say that I love your website. My husband and I followed your instructions on building our own home. Most of the work we did ourselves, but not all. We saved $90,000 in labor costs and now have a beautiful home that we own.

I built my own home doing all my own labor. My house costs me around $70,000 for materials. It took me 8 months to build and is about 2,000 square feet. I didn't think I could do it, but your house web site encouraged me. I used all the info you had.
Benny Luis Lopez,
I can't thank you enough for your free information web site about home building. I was looking for Electrical wiring diagrams when I found your site. It was very helpful.

My wife and I lost our home to foreclosure but we kept a plot of land to start over. We are halfway through the construction of our house. Your website gave us hope to start over and build a house with low payments. We are in our late 60's but we find it rewarding to put so much effort into a project that will reward us for years to come.
