Air Barrier Evaluation

BEA provides air tightness testing which is a process in which the building envelope is tested to quantify the air tightness. The test measures air leakage rates through a building envelope under controlled pressurization and depressurization.

  • ASTM E770 - Standard Test Method for Determining Air Leakage Rate by Fan Pressurization.
  • ASTM E1827 - Standard Test Methods for Determining Airtightness of Buildings Using an Orifice Blower Door.
  • Diagnostic Smoke Infiltration Testing under negative building pressure.
