Sealing and insulating the "envelope" or "shell" of your home or building is often the most cost effective way to improve energy efficiency and comfort. In order to create a better thermal envelope, consider the second law of thermodynamics. This law states that heat flows in one direction, from a warm space to a cold one. Warm air inside a building structure will flow to the cooler air outside during winter months.

Infrared Thermography
We use a special infrared camera as one of our tools to identify air leaks, moisture problems and insulation voids in building structures.
 The dark colors in this infrared photo show the penetration of cold air through a poorly sealed door.

The illustration above shows many common ways that residential and commercial structures lose heat during cold outdoor temperatures.
(Left) We use a Blower Door unit as another way to test for air leaks. A fan in the unit blows air to the outside, mildly depressurizing the building structure. Outside air returns into the building structure through all the nooks, crannies and poorly insulated spaces in the building. This allows us to track down and seal air leaks. |
