Thermography is used to detect thermal defects, moister or air leakages in building envelopes.
Air leakages are not visible to the naked eye, so thermal imaging can detect whether insulation is needed or not.
If you are wondering why your electricity bill is so high, or think your air conditioning isn't working, it may be because there is a leak in your home.
Infrared scanning is also used to detect hot electrical connections. This is to insure safety. If a connection is hot, it may be a fire hazard and needs to be replaced.
It is always best to be safe. Getting infrared scanning of your home or business is beneficial to detect anything regarding temperatures that you may not have known existed.
