Take the 1:5:10:365 challenge: Do one thing – for 5 to 10 minutes – 365 days a year to make our home and planet environment better.

1:5:10:357 EcoTip: Air washing occurs when air leak in the building envelope allow air to flow through insulation – reducing its effectiveness. Air washing can be diagnosed using thermal imaging or thermal leak detection in combination with creating a strong negative air pressure when the temperature difference between the inside and outside is at least 20 degrees F.

Performing the inspection without negative pressure (:356) helps evaluate the effectiveness of insulation when there is little or no wind or other pressure forces. Performing the inspection with a negative pressure simulates the way the building behaves when outdoor conditions are windy or there are other pressure forces present.

It is important not to cause back-drafting which can result in carbon monoxide poisoning or fire from flame roll-out when conducting negative pressure tests for air washing.
