Identifying leakage areas with a smoke generator

Updated: Jan 24, 2020

This video shows air loss around and through parts of the window frame testing with a blower door and smoke generator to aid in identifying the areas. The building will be for student accommodation and so has a large number of windows. Each window will be a penetration in the building envelope and air tightness barrier, so sealing the windows to the building is very important.


The building has a design air permeability of 3 so it is vital to fix any issues earlier on in the project to prevent a fail and expensive remedial works when carrying out the final air pressure test. This project has a value of £12.5M so the construction and the quality of the build is taken seriously and checked at various stages of the build.


If you have a project and are not sure if you have any air leakage areas in your new build then please get in touch with REDFANsolutions to see how we can help.
