Passivhaus standard build in Everton Heath
#IMCASESTUDY3
“The devil is in the detail.” This phrase rings true, especially in construction projects where achieving exceptional airtightness is critical. We ensure success by starting all our projects with Passive Purple Brush, a highperformance liquid membrane that plays a pivotal role in achieving the desired air test score.
Background
Oriented Strand Board (OSB) joints are common points of air leakage. Passive Purple Brush effectively seals these joints, preventing air infiltration and ensuring a continuous airtight barrier. By sealing all critical areas with Passive Purple Brush, we achieve consistent and reliable air test scores, often surpassing stringent standards such as Passive House requirements.
