Introduction to Thermal Anomalies
 

Click to EnlargeThermal anomalies are occurrences of irregular temperatures (conductive, convection, and radiated losses).  Virtually anywhere in the building structure where there is a joint, junction, or opening, there is potential for air leakage.  With the use of infrared imaging, one can identify thermal irregularities in and on the building structure.  Once the irregularities are identified, it is important to have them properly fixed.  Correcting the irregularities can highly increase building efficiency and structural integrity.  Excessive air movement significantly reduces the thermal integrity of the structure and is, therefore, a major contributing factor to energy consumption in a building.  All windows, attic stairs, scuttle holes, and exterior doors should have proper insulation and weather stripping.  In some cases, you may find that the integrity of the window itself is the problem.  Over time, insulated windows can loose their gas from within the window.


Notice the missing insulation across the top six feet of the wall.

 

Insulation is an extremely important factor when it comes to decreasing thermal leakage.  Insulation that is improperly installed, missing, old, or compressed can lead to air leakage.  Insulating wall switches and outlets can reduce the amount of unwanted air movement.  Insulating the hot water heater can greatly reduce thermal loss, and also help lower your power bill.

With the skyrocketing cost of fuel, you know your energy bill will soon follow… With the aid of thermal imaging, leaky ductwork, compressed or, missing insulation, poor connections to air handling equipment can be precisely identified, so that it can be corrected. Some problems are not very big but add ten or so together and you can have quite a bit of energy loss.  Inadequate insulation can be a big drain on your wallet. Thirty three percent of you heating and cooling is lost thru your exterior walls and twenty five percent thru your roof. Buy having an infrared scan performed; you will be well informed of the insulating properties of your structure.  When building or purchasing a home or before sighing off this is good information to have, the problem can be rectified, saving you money and having a structure that performs as intended. Remember an infrared scan pays for itself in energy savings.

Insulation from factory is folded and not fitting correctly


Heating and air conditioning leaks are not always noticeable.  The air handler, duct work, joints, and connections are prime suspects for air leakage.  Leaks in these areas can not only increase your power bill, but can also cause the unit to run harder and longer than it should.
 

 

Notice how much air is escaping from the top.  With the light off, you can see that air is moving through the light fixture due to a leak in the duct.
