Air Tightness Testing In UK http://www.southern-assessors.co.uk/


What is Air Tightness Testing • Air Tightness testing also known as Pressure Testing is a mandatory requirement for newly built homes and commercial buildings under Part L1 of the Building Regulations. • Air Tightness testing is the procedure to trace any unwanted drafts and uncontrolled airflow through the house. • Air Testing is necessary for any kind of newly building structures to comply with the stringent features under Part L1 of the Building Regulations for performance evaluation.

Effects of Air Leakage • Air leakage is an uncontrolled flow of air in the cracks and some parts of the building that can accumulate large amount of moisture in the fabric of the buildings and harm the occupant’s health in the long run. • Air leakage has also impact on energy efficiency,sound control and fire control. • Excessive Air leakage leads to difficult situations while controlling ventilation systems. • Air leakage of few building can be sometimes better than ventilation and airconditioning (HVAC) systems during extreme conditions.

How Air Testing is done? • Leakage of air is measured with a door blower fan system which is placed at outermost entrance of the dwelling. When the Equipment is fixed and ready to test, then all of the ventilations in the building have been completely closed as per the Pre-Test checklist conditions. • The test measurement is determined by the leakage of air (m3/hour) in or out of the building per square meter of the buildings inner envelope with a considerable pressure of 50 Pascal’s with a difference of inside and outside of the building.

Why Air leakage testing is done? • Air Leakage Testing is necessary for all buildings to reach the targets under Part L of the Building Regulations. • In order to maintain air tightness, Air Leakage testing is compulsory in buildings because we cannot detect them by simple visual inspection. • Air leakage can cause storage of excess moisture which can cause harm to the occupants of buildings.
