Infrared (Thermal) Imaging Detects Missing/Defective Insulation

It's that time of the year again. It's getting colder outside and Infrared imaging can now detect those insulation defects that the summer months didn't allow for a Delta T (difference in temperature). Most homeowners do not realize that a difference in temperature (cold on the exterior and warm on the interior or vise-versa in the Summer months with air conditioning) must be established in order for an IR camera to detect faults in their homes. It's now getting to the point where exterior temperatures are lowering and the heat is being turned up. That gives me the perfect setting to detect those insulation voids in your walls and ceilings.

Check out the IR images I have captured in the past...

Exterior wall appears to fine, but infrared detects efficiency issues
insulation voids


infrared line
This is an exterior wall with no insulation issues. The structural member locations are clearly visible (with infrared) from colder studs conducting onto the interior drywall.
insulated wall cavities


infrared line
During the colder months, a perfectly insulated wall will contain cold structural members (see image above). In this home, the studs are warmer than the cavities. This is clearly indicative of "no insulation" in these wall cavities.

infrared line
This is another home with the same situation...empty wall cavities. This uninsulated wall is equal to leaving your windows and doors wide open.

The attic cavity above this particular ceiling was not accessible. Access openings were not installed for my inspection. That didn't stop me from investigating further. My infrared camera has no problem detecting a shoddy installation of insulation. The heat loss here would be significant.
ceiling insulation missing


infrared line
This lower ceiling surface looks great visually, but my thermal imaging camera detects an excessive void at the wall and ceiling cavities.

This newly constructed home had insulation missing in several wall cavities

A client inquired about ice damming on their roof. You can clearly see the voids at the rear portion of these two skylights. This void allowed interior heat to escape and melt the snow on top of the roof (above this area) and cause major ice damming.

infrared line
The soffit around this particular skylight contains recessed lighting that does not allow insulation contact (Non-IC lighting) per manufacturer. An upgrade to more expensive recessed light fixtures (allowing insulation contact - IC lighting) are no option, in order to properly insulate these type of ceiling cavities and prevent ice damming on the exterior roof edge.

The stud cavities around this window were obviously not insulated.

Cathedral ceiling cavities are impossible to inspect visually, but thermal imaging has no limitations. My infrared camera detects missing insulation throughout one side of the gable. The heating bill in this home will be costly until it's insulated.

The cellulose insulation in these wall cavities has settled quite a bit

More settled cellulose insulation. Infrared also detects heat piping inside this wall at the top right of IR image.

There is no perfectly insulated home out there. I will always detect imperfections in a building. I've even detected openings in foam insulation. As tight as you would think foam insulation might be, it's not a perfect insulator, as I will discuss in my next Blog.

If you're interested in scheduling an Infrared scan and you reside in eastern Massachusetts or South Eastern New Hampshire, please contact me at 978-683-4984 to schedule your Infrared (Thermal) Imaging scan of your home.

Optional Home Inspection Services

  INFRARED (THERMAL) IMAGING This optional service is totally amazing. I basically utilize my infrared camera to detect hidden issues behind the finished surfaces of your building. If there are finished walls or ceilings in the living areas, basement or attic that are situated on the exterior shell of the structure, my IR camera can detect insulation voids or concealed issues that can be revealed without destroying or removing the wall/ceiling material. It’s simply an infrared imaging and measurement camera that can actually "see" and "measure" thermal energy emitted from an object. I can then map out and interpret these thermal readings which can reveal serious issues that cannot be seen by the naked eye or with any conventional or digital photography. Infrared Scanning - $150.00 an hour ($150.00 for a professional IR report )   DRUG TESTING Yes, you are reading this correctly. I can actually test your prospective home for drug residues with

LEAD PIPES AND LEAD PAINT

Lead Paint New LEAD LAWS enacted on April 2nd, 2010 All building contractors performing renovation, repair and painting projects that disturb lead-based paint in homes built before 1978 must now be EPA certified and must follow specific work practices to prevent lead contamination throughout your home. Before you hire any building contractor that will be distrurbing suspect lead paint, please have your home professionnally tested for lead paint. If your home  does have positive results of lead paint, your renovation contractor must be LEAD-SAFE Certified before touching anything in those areas that tested Positive. Simply look for the LEAD-SAFE CERTIFIED logo before you hire any renovation contractor ... LEAD - WHAT IS IT Lead has been mined, smelted, and compounded for thousands of years. Lead is a neurotoxin metallic element that was historically used in paints, gasoline and plumbing materials for many years. Lead was easy to work with for a variety of purp

PURCHASING A HOME WITH ALUMINUM WIRING

This picture is a perfect example of the problems that are associated with Aluminum wiring. Note letters A and B (the insulation jackets are melted), which I will explain "Why" in the third paragraph and C (mixing copper wiring with aluminum wiring on the same breaker). Aluminum wiring can not be mixed with copper wiring and breakers can not be double tapped with two wires, unless designated by manufacturer and the breaker connnection will contain a special clip for double tapping. Aluminum wiring is very easy to identify due to it's obvious aluminum color. Aluminum wiring is not to be confused with tin coated copper which looks similar to aluminum wiring but aluminum wiring has distinguishing characteristics and is a solid conductor. During the 1970's, aluminum (instead of copper) wiring became quite popular and was extensively used throughout the United States. Since that time, aluminum wiring has been implicated in a number of house fires, which caused jurisdict
