R-value is measured under laboratory conditions, but in the real world there are other factors that determine how effective a particular type of insulation may or may not be. Conduction, convection, and radiation all affect heat loss, but R-value only measures the first one, conduction, which is when heat is lost through solid materials. Radiation [...]

The Federal Trade Commission (FTC) considers R-value to be an integral part of spray foam measurement, and the FTC defines how R-value is reported and tested. The thermal performance of insulation is measured by R-value. R-value is a test performed under laboratory conditions and measures resistance to heat flow. The testing methods were developed by [...]

It can always be challenging to keep a building’s occupants satisfied with their environment. Here are a few quick things to check before deciding to make major renovations: Check dampers. A stuck damper can result in much more dramatic temperature imbalances in your building. Check thermostats. A problem here may not necessarily be caused in [...]

The American Society of Heating, Refrigerating and Air-Conditioning Engineers states that thermal comfort is achieved when 80% of a building’s occupants are satisfied with the environmental conditions. While it is extremely challenging to satisfy everyone all the time, particularly when people have varying metabolisms and methods of dress, there are some things that can be [...]
