Airtightness Installer Training

Airtightness Installer Training

We can make sure you have the skills you need to become an airtightness installer. We offer a training service, that gives you all the necessary tools to meet airtightness building regulation standards. We offer a hands on, one day, training course giving you all the theoretical knowledge, along with practical installation demonstration. 


10.00 – 11.15 – Theoretical Part:
– What is Airtightness and Vapour control.
– Why do we apply airtightness/Vapour Control products.
– What is the difference between Air- and Wind tightness.
– Airtightness Ventilation.
– Most common failure areas.

11.15 – 11.30 – Coffee break

11.30 – 12.30 – Solutions on Site:
– Designing, Building and Testing for Airtightness.
– Intelligent onsite solutions.
– Airtightness details and solutions (Steel, Masonry & Timberframe).
– Air Testing and other Quality Control measures.
– Airtightness in the Irish / UK context, present and future.

12.30 – 13.00 – Lunch

13.00 – 13.30 – Practical Demonstration:
– Demo house overview.
– Airtightness best practice detailing review.
– Airtightness quality assessment.
– Identification of common leakage points in block and timber frame.

14.15 – 15.00 – Exam + Q&A



Each participant of Airtightness Installer Training Course receives a LABC installer certificate, product samples, a memory stick loaded with relative information including airtightness video tutorials and a direct contact with our engineers.

Condensation Risk Assessment

Passive House Systems advises its customers using WUFI® software, which is fully compatible with BS EN 15026, and dynamically predicts moisture movement and storage as well as condensation for each location. Using WUFI® enables architects, designers and developers to identify the likelihood and risks of condensation, and enables designs to be optimised for longevity of the building fabric, and for the health and wellbeing of the buildings occupants.

WUFI® is an acronym for Wärme Und Feuchte Instationär, which, translated, means heat and moisture transiency.

WUFI® software was developed by the Fraunhofer Institute for Building Physics in Germany and provides detailed heat and moisture calculations based on local climate conditions for building materials, multilayer components and even whole buildings.

The designer is able to achieve a minute-by-minute prediction over a given period of years, as specified by the designer. The programme considers a worst-case scenario with the injection of a moisture source at the source to predict the robust drying out of the fabric build up.

A further enhancement of using the WUFI® software is that external weather including driving rain and solar radiation is predicted in a cycle and the designer can choose the specific internal environment that the building will be exposed to. This has proven invaluable when assessing the correct position for high performance vapour control and vapour permeable membranes to ensure a healthy building fabric, whether it be roofs or walls.
