Overview

This project in Norwich, was a new build where vapour control wasn’t looked at before we were approached. With so many substrates to contend with, is Passive Purple up to the job?

Background

We had PIR boards, spray insulation, OSB boards and even had steelwork that we had to get around and make airtight. With a mixture of products from Passive Purple Internal vapour Control to Passive Purple Brush, you will see from the pictures, there is a continuous purple line all throughout the building

Challenges

The journey was filled with obstacles at every turn. Steelwork presented a particularly tricky problem, requiring creative solutions to ensure a seamless vapor barrier. With a mixture of products from Passive Purple Internal vapour Control to Passive Purple Brush, we meticulously sealed every nook and cranny, leaving no space for moisture to infiltrate. As the project progressed, a continuous purple line emerged, snaking its way throughout the building like a ribbon of determination. Even with all the different substrates, our installers still ensured airtightness without compromise.

Solutions

With a Passivhaus certified score of 0.03ach (20x lower than the required 0.6ach) Passive Purple can guarantee you a score of 0.6ach (air changes per hour) and under. Whether you’re trying to achieve certified Passivhaus or just build to a Passivhaus standard, Passive Purple is your answer!

Results

We managed to achieve a 0.5 ach (air changes per hour) test score on this project which we think is pretty amazing considering airtightness was an after thought.

Air Testing

Air testing- also known air testing, air permeability testing, air leakage testing, and air pressure testing- measures the amount of air escaping through a buildings envelope.
