Meeting the Air Leakage - Energy Codes

So when indoor air is warmer than the outdoor air, it escapes out of the upper levels of the building, through open windows, ventilation openings, or penetrations and cracks in the building envelope. The rising warm air reduces the pressure in the base of the building, forcing cold air to infiltrate through open doors, windows, or other openings.NONWOVENS TESTING SGS-IPS TestingFrom Stiffness, Abrasion Resistance and Air Permeability to Barrier Properties, Water Vapor Transmission and Flammability, we utilize various test methods to tell you how your materials stack up against your objectives and your competitors.

The rate of air flow is adjusted until a specified pressure difference between the two fabric surfaces (face and back) is achieved. The air flow is measured and the air permeability is calculated.Air Permeability - an overview ScienceDirect TopicsPermeability - AAPG WikiFeb 02, 2016Permeability is the capacity of a rock layer to transmit water or other fluids, such as oil. The standard unit for permeability is the Darcy (d) or, more commonly, the millidarcy (md). Relative permeability is a dimensionless ratio that reflects the capability of oil, water, or gas to move through a formation compared with that of a single-phase fluid, commonly water.
