EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of EN 12114 testing. This standard defines a general laboratory test method for determining the air permeability of building components or structural elements when exposed to positive or negative air pressure differences.
Their descriptions specify test equipment and procedure and provide guidelines for the interpretation of results. The appendices give indications about the test conditions and a method for expressing results using a regression technique. This standard does not apply to all buildings or site measurements.
Heavy rain resistance and air tightness of building components and structural elements are required by law. Despite this, consumers often demand stricter requirements for airtightness. The physical situation regarding the tightness of the joints is complex. For example, particles moving in a joint are important as a dynamic flow.
Sealing is due to convection, that is, to heat conduction in a fluid by the displacement of molecules. Convection is the transport of material or physical properties due to the spreading motion of particles. Diffusion in a closed system allows different concentrations to separate. By applying the test method described in the EN 12114 standard, the effect of different gaps or sealing materials for different connection types is determined.
Ventilation represents a significant portion of heat loss in winter and results in the need to minimize airflow. However, it is absolutely necessary to ensure the indoor air quality and the safety of users and to control the risk of condensation. In general, ventilation is responsible for 30-40% of the energy consumption used in air conditioning in buildings. Air exchange rates vary greatly from country to country and the minimum value takes into account comfort, sensory and hygrothermal criteria.
Air permeability tests are carried out to characterize the air permeability of buildings and components. The data obtained is particularly useful for improving the design of building components, for example windows and shutter boxes, and for performing simulations with reliable data.
