Some people barely consider the insulation in their new home. After all, it is hidden in walls and attics where you never see it. In fact, it's sometimes a good feeling when that ugly looking stuff in the wall cavity is covered up and seen no more. You may say to yourself, “As long as the insulation meets code, I’m fine with it.” Or you may take pride in using the very best insulation system to keep heating costs down.
In my early years in construction, I would buy a couple old homes a year and remodel them on the side while working full-time in construction. I recall some homes had 1x10 boards as exterior sheathing underneath the siding, but no insulation in the walls. Other homes had 1x10 boards covered with rosin paper to stop air from flowing through the cracks. Then, as the years went by, asphalt felt paper replaced rosin paper due to deterioration issues. I recall one home even had newspapers inside the exterior walls for insulation. Those newspapers dated back to 1934!
Today, there are a ton of insulation products on the market for both residential and commercial buildings. Some products have been on the market for a long time, while others are brand new and still being refined. Let’s look at a few of these.
When you are considering what insulation to use on your next project, you should think about more than R-value. Also consider fire rating, whether the material is non-hazardous, mold resistance, pest resistance, vapor barrier, and pricing. Many commercial building designs allow wall and ceiling insulation to be exposed, which makes appearance a factor as well. Doing your research and seeking advice from professionals can help you choose the best product for your project.
