Air Pressure Testing
Air pressure testing is a method by which Clean Footprint Ltd measure the air tightness of your home. The aim of air tightness testing is to measure the flow of air within a building and identify areas that are experiencing heat loss. It will also highlight how well your property will retain heat and in turn reduce carbon emissions, making it more efficient and cheaper to maintain.
The revised building regulations (24th January 2008) introduce mandatory air pressure testing for new dwellings.*All new single dwellings will require an air pressure test from 1st July 2008.
What is Air Tightness?
Air tightness measures the flow of air in and out of a building. Air leakage is the uncontrolled flow of air through gaps and cracks in the fabric of a building. Improving air tightness in a dwelling can reduce air leakage. The aim of air tightness is to "build tight, ventilate right". This means that there are no breaks or gaps in the envelope of the building fabric and there is complete control over the ventilation system within the building. Having an airtight property does not mean there is insufficient air flow, it means there is controlled air flow. The only satisfactory way to measure air tightness is by using blower door test equipment.
Cleanfootprint Air tightness testing highlights areas of heat loss. These areas are increasing your energy consumption and, with it, the amount of money your property is wasting. Air tightness and thermal imaging can locate these areas and therefore allow you to make the necessary changes to increase the energy efficiency of your home.
Air Tightness for Existing Dwellings Draught - Detection
Air tightness testing is a legal requirement on new dwellings only. However, if you find your home is draughty, you could be losing up to 30% of your main heating bill through these draughts. The draughts are caused by gaps and cracks in the building fabric and are most likely out of sight.
Cleanfootprint offers draught detection to the existing house market. The aim of the service is to improve the comfort of the home in which you live. The service includes a report which, if followed, will reduce the heating cost and will improve the comfort of your home.
Why use Air Tightness testing and Thermal Imaging together?
Air tightness testing and thermal imaging complement each other. Their combined use indicates air leakage within a property. Once these have been identified, solutions can be decided upon that will increase the energy efficiency of your building, and save you money over time.
