Air Tightness Testing & Thermal Imaging

As seen on 'Duncan Stewart's About the House on RTE'

Eco Home Insulation offers air tightness testing for residential dwellings. 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. Guidelines have been set out in relation to developments. These guidelines are outlined below. The aim of air tightness testing is to measure the flow of air within a building and identify areas that are experiencing heat loss.

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.

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 TEsting - Eco Homes InsulationAir 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.

Eco Home Insulation 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.

What is Thermal Imaging?
Thermal imaging is used to identify patterns of heat loss from your property that are invisible to the naked eye. Thermal imaging is conducted using a high tech infrared camera. This camera is able to determine the pattern of heat loss through the fabric of the building and heating systems.

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.

What are the benefits of Thermal Imaging?

  • Real time capture of heat loss.
  • The ability to see things that are invisible to the naked eye.
  • Highlights the extent of the heat loss- it does not merely identify that heat loss is occurring, it also indicates the level of heat loss experienced.
  • Identifies defects that exist.
  • Money can be saved by dealing with the issues that are identified by the thermal imaging report.

Where can Thermal Imaging find defects?

  • Insulation defects in walls and roofs.
  • Air leakage around service pipes.
  • Heat loss through un-insulated pipe work.
  • Defects in radiators and underfloor heating.
  • Energy wastage in electrical appliances.
  • Problems with ventilation and air conditioning.
  • Electrical problems.

What are the guidelines in relation to developments?

Number of Units Number of Tests Required
1-4 One Test **
5-40 Two Tests
41-100 5% of Dwelling Type
101+ (if target is reached)
101+ (if target is not reached) 5%

* The regulations apply to new dwellings where planning permission has been applied for on or after the 1st July 2008 and where substantial works are not completed before the 30th June 2009.
** For small developments, no more than three dwelling units, a specific pressure test may not be necessary. If it can be demonstrated by way of a report that during the preceding 12 months a dwelling of the same type constructed by the same builder achieved an acceptable standard.

Let Eco Home Insulation help you enjoy a cosier, more energy efficient home.
