Thermal stability of lightweight frame partitions exposed to pulsed wind load

Much has been said about air infiltration, especially of ventilation losses and air quality. There is less information on heat losses through increased convection. This problem particularly concerns on one sided wind washing of the building envelope characterised with seeming airtightness of construction partitions. On the base of measurements undertaken in existing buildings constructed as lightweight timber structures filled with fiber materials it can be seen that air filtration also contributes to increased heat transfer through the building envelope. This paper presents the results of the research on the thermal stability of building partitions insulated with fiber materials and exposed to pulsed air filtration due to the wind load
