Frequently Asked Questions
Air Pressure Testing
Air pressure tests calculate air tightness in a building, known as “air permeability” or “leakage”. Air leaks are the air that escapes from the building by uncontrolled means. Leaks can occur through voids, holes or cracks in the building fabric.
Domestic Air Pressure Testing .We have iATS certification to perform every test according to I.S. EN ISO 9972:2015.
VALUE Air pressure tests from £175.00 + VAT with substantial discounts when multiple dwellings can be tested at once.
A good air permeability test result will improve your Dwelling Emission Rate (DER) or Building Emission Rate (BER) and reduce the heating bill of the house or building.
The duration of the air leakage test should take no longer than two hours. If the property passes a certificate will be issued which should be passed to the building control (Building Regulations) body within seven days of the air testing test being carried out. Contact us. We will be able to assist you through the entire air testing process, from preliminary design to the final testing stage.
If you have constructed a new dwelling, then Part L of the Regulations states that you must now have an air tightness test performed on that dwelling to assess air leakage. The air permeability of the building must meet the latest Building Regulations standard for conservation of fuel and power (currently 10m3/h/m2 @ 50 Pascals).
Air tightness construction is a draught-free envelope – quite simply this means that there are no unintended gaps in the envelope that allow air to leak in or out of the property. This means there are no cold draughts coming in through the property.
A standard house has an air tightness of between 5 to 10 Air changes per hour. This means that on a windy day the air in your house changes from warm air to cold air up to 10 times in 1 hour. This means that you have to heat the air 10 times in one hour.
Tips to Help Pass an Air pressure testing first time by stopping air leakage:
1. Every service penetration is sealed.
2. All plumbing work is complete with water in the traps.
3. Build to Accredited Construction Details.
4. Gaps within walls and floors must be sealed.
5. Bathrooms and kitchens must be fully fitted and mastic sealed.
6. No work trades to be in the property where the testing is carried out.
Air testing is a recognised method of measuring the extent to which air is lost through leaks in the building fabric (air leakage). It is sometimes referred to as air tightness testing.
SAP calculations are used to work out the energy performance of a residential dwelling, one target component of the SAP Calculation is air pressure testing that measures the air tightness of the dwelling.
