It saddens me that I have to revisit this topic again, but I recently came across a company from the UK that carry out most of their electrical thermography with covers on and doors closed.

Some people will argue that training is more important as you cannot gain experience without training. There are … Read More
For many years I have conducted surveys of roofing systems. There are many different roof types and the most successful are flat or low sloped roofing systems.
