Air tightness testing, often referred to as an air leakage test or air permeability test, is a valuable method for measuring the extent to which air is lost through leaks in the building enclosure. Knowledge of the air leakage rate of a building is critical to reduce energy consumption 和 to improve comfort for the occupants.
im体育APP provides air tightness testing of various types of assemblies used in building enclosures, 从 空气的障碍 to 开窗术 和 包层 产品. Since air leakage is not only responsible for heat loss 和 low occupant comfort, but it also enhances the risk of moisture damage, we pair our testing with water penetration tests under uniform or cyclic static pressure difference. Our goal is to ensure that the materials used in building enclosures will prevent air 和 water infiltration, allowing for lower CO2 emissions, better indoor air quality, 和 fewer issues due to moisture brought in by outside air.
测试 for the air tightness of building 产品 is particularly useful during the design phase 和 the construction process of new buildings as well as during retrofits. It confirms that air tightness targets are met 和 avoids undesirable 和 costly problems during the service life of the building.
