A Guide to Properly Installed Insulation:

While building your home, getting near the insulation phase, you may start doing some research about insulation

  • This can quickly become complicated
  • There are different types of insulation (Foam, Fiberglass, Blow-in, Cellulose even Cotton)
  • There are different climate zones which have different requirements for your home.
  • Vapor barriers, ventilation, air sealing, title-24 requirements and more.


Let’s talk about a couple of these:

Wall Insulation:

Wall insulation should be installed touching all 6 sides of your wall cavity. Any gap or void in your walls means energy loss. We all know what that means: bigger energy bills. Problem areas include the top and bottom of your walls, around electrical outlets, and the many obstacles found in the walls of any home built today.

One of the most important things that is frequently overlooked is insulation pushed too far into the wall cavity. This is know as “over compression” of the insulation. When your insulation is not at its full thickness or is pushed far into the wall cavity, this can lower your R-Value.

NEED TO KNOW: R-Value represents the effectiveness of you insulation to resist temperature change.

A batt of R-19 installed poorly will lose as much as half of its R-Value. If this is not corrected before you install drywall, this will result in energy loss for the life of your home. Over the years, this adds up to many thousands of dollars out of your pocket. Obstacles within your wall cavities are often places where much energy loss come from. Coldani Insulation installs insulation the correct way, every time.

Ceiling Insulation:

The insulation in your ceiling is the most important of all your home insulation. Especially in California’s hot summers, the attic of your home is much hotter than the air outside you walls. Your ceiling insulation is very important and is responsibly for saving you more energy and money than any other area.

Insulation install methods and guidelines are similar in your ceilings. The main difference is this is more difficult to do right because your ceiling insulation is thicker and attics often have more obstacles with the potential to lower you R-Value.

NEED TO KNOW: An R-Value of insulation out of the bag has to be installed with care around all obstacle to keep its R-Value after installation. Often an R-19 can be as low as R-10 or less if incorrectly installed.
