Blower door tests, duct blaster tests, and thermal infrared imaging are vital parts of the quality control program that Nu-Wool provides in the field. In addition to showing the effectiveness of the insulation, these tools can be used to find electrical problems, roof leaks, thermal breaks, leaky ductwork and other problems.

	Blower Doors Blower door tests are an accurate and scientific way of demonstrating where a building has air leakage or infiltration.
	Duct Blasters A duct blaster is used to directly pressure-test the duct system for air leaks, much the same way a plumber tests water pipes for leaks.
Infrared Cameras Thermal infrared imaging uses a heat sensitive camera to "look" into a wall or ceiling and locate where a thermal problem may exist within a building.
