Generally, before the application of Passive Purple, we seal all gaps and joints like so and pay close attention to the joist zones, window reveals and panel to DPC/top plate connections.
This prepares us for spraying a smooth quick coat knowing nothing has been missed and guarantees a perfect airtight score. Also whilst doing this, it helps locate and amend any issues with the structure that may be unknown to the client or contractors.
Our onsite philosophy is.. If every contractor works to and airtight standard detail, this level of precision and careful quality of work flows through the job and makes the final structure perfect with minimal issues ‘if any’ in all areas and trades.
