Part F extract fan testing and thermal surveys throughout the south of England
Full Air Flow Extract testing, in accordance with the Building Regulations Part F. This is carried out by our competent ATTMA registered technician’s.
Over the last few years buildings have become more insulated and air tight. Because of this improved efficiency it is important that all ventilation systems installed in a new property are working properly, and that they are also commissioned and balanced correctly to ensure optimum levels of performance.
Part F of the Building Regulations requires that intermittent extractor fans installed in toilets, bathrooms, and kitchens along with mechanical systems such as MHVR Systems are tested to ensure their flow rates meet Part F requirements, and are working efficiently.
Having been tested results must be submitted to building control to ensure that the building fully complies with the current building regulation requirements.
Full flow rate testing can be included with you air tightness testing at a reduced rate or be provided as a standalone service.

Thermographic surveys of buildings
are typically carried out in the winter months when building's heating system is operating and there is a suitable internal-to-external temperature difference. To limit the effects of solar gain, building surveys are carried out at night or the early hours of the morning to ensure any radiation from the sun has suitably dissipated avoiding unreliable results from the survey.
To achieve a reliable result from the survey, preparations need to be made to ensure the building fabric has been sufficiently heated and that there is a minimum internal–to-external air temperature difference of 10°C both prior to and during the survey. To achieve this, the heating should be in operation a few days preceding the survey to heat through the building fabric.
On the day/night prior to the survey, the heating should be set to run constantly throughout the night at a temperature that will achieve a minimum
internal–to-external air temperature difference of 10°C. To assist in maintaining the temperature difference throughout the building, all windows/doors should be kept closed as far as is practical prior to the survey.
