OVERVIEW

In this project, we ensured full coverage on all surfaces—
floor, walls, and ceiling. Each flat needed to be individually airtight. Initially, Passive Purple Brush was used to cover all joints, large gaps, and floor-to-wall junctions. Following the preparatory phase, Passive Purple Internal Vapour Control was applied, creating a seamless airtight and radon barrier finish.

BACKGROUND

The install only took one day, as we ran into zero problems. We love a challenge but we also love a hassle free project. We even astounded the air tester! A complete airtight apartment with an intelligent liquid management system.

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

The air test results were extraordinary: the air tester found the score so exceptionally low that he thought his machine was malfunctioning. After recalibrating, it was confirmed that the score was indeed accurate, achieving a value ten times better
than the standards for a passive house. These flats now boast an air test score of 0.035 ach (air changes per hour).

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.
