Locating Missing, Damaged, Settled or Wet Insulation

January 16th, 2009

All homeowners pay a lot of hard earned dollars to heat and cool their homes today and I know everyone would love to cut the costs of conditioning their homes. With the continuous rise in heating fuel costs, the only ideal way to save money is to locate and seal those breached areas of your home that are stealing your energy dollars. If you are able to retain conditioned air inside your home for a longer period of time, you will be spending much less money on the fuel that is powering your heating system. In a typical home, space conditioning and comfort bills can account for up to one-half of your home’s energy bills, with the remaining portion due primarily to heating your domestic water, interior lighting, and your appliances. Knowing that space conditioning accounts for half your energy bills, I can show you how you can lower this expense now.

What you need is an infrared inspection. An infrared inspection is a brilliant method of providing you with an instant snapshot of active energy losses through the interior walls and ceilings of your home. Thermal imaging will visually show thermal mapping of any damaged, settled or improperly insulated cavities throughout your home. Appreciable temperature differences, (due to variations in thermal energy heat transfer) allow me to determine the adequacy and proper installation of the concealed insulation that is installed throughout your structure’s exterior cavities. I’m able to detect obvious insulation issues while scanning your exterior ceiling and wall surfaces. Deficient insulation is a poor insulator, which makes it a great conductor of your conditioned air, and this is what enables me to easily detect the thermal anomalies in these areas. Any major differentials in surface temperature are going to be the obvious areas that are going to require you to upgrade insulation, in order for you to start saving energy bucks.

Keep in mind that there are always going to be minor air breaches in typical exterior walls and ceilings, due to wood structural members that will conduct exterior air and simply can not be insulated. But, I would like to walk you through your home and literally show you the major areas of concern where excessive air is infiltrating your conditioned living area, causing your energy bills to become sky high.

After pointing out the areas of your home that can be improved, I will be providing you with a professional report which will be highlighting those areas that are in need of an insulation upgrade. You can then use my infrared report as a guide to locate those deficient areas when upgrading or simply hire an insulation contractor who can then utilize my report as a guide to upgrading the insulation defects and fissures.

A visual inspection of this ceiling indicates that nothing is wrong, but my thermal scan reveals missing insulation throughout the outer rim board area.

This children’s room looks fine visually, but my infrared camera reveals missing insulation throughout the top portion of these stud cavities.

Visually, this wall appears to be in great shape, but my infrared scan detects missing insulation behind this attic knee space. This cold air infiltration is as bad as leaving a window ajar.

I was hired to inspect a recent installation of blown-in insulation. Visually, it looks fantastic, but infrared reveals shoddy workmanship.

IR Camera Comparison

December 1st, 2008

For many home inspectors that are investigating the possibility of purchasing an infrared camera the choices and features of the many cameras on the market can be daunting. Here is a spreadsheet showing some of the more ‘inspector important’ features and specifications. This is not an exhaustive collection of cameras and features but rather a place to start your own due diligence and comparisons. You can Print or Download the file here: IR Camera Comparison
