Ventilation Validation


Q50 is a Registered Ventilation Validator under the NSAI ventilation validation scheme. 

The 2019 revision of the Part F (Ventilation) of the Building Regulations has mandated that ventilation systems be checked by an independent third party for flow rates after commissioning.

For consumers, the benefits of Ventilation Validation are immense in terms of energy efficiency of the dwelling improvement and indoor air quality improvement, providing enhanced comfort and health benefits to the occupant.

Thermal Imaging
Thermal Imaging Surveys


We an help you to locate and record areas of your building that have insufficient or missing insulation - in walls and roofs.


Building Thermography can also be used to identily and record thermal bridges at key junctions in the external envelope - such as between the roof and the external wall or the floor and the wall.


Infrared Imaging is great for identifying sources of draughts around window and door openings. The captured image clearly shows the extent and source of the leak.
