Project Spotlight: Seven Mills, Dublin - Delivering Passivhaus at Scale
We're proud to have supported Cairn Homes' Seven Mills development in Dublin 22, one of Europe's largest Passivhaus residential developments. Comprising 607 high-performance apartments, the project demonstrates that Passivhaus standards can be successfully delivered on a large-scale, high-density residential scheme🏠
Working alongside SF Plastering, Partel supplied and supported the airtightness strategy, providing technical expertise, product education and on-site guidance to help achieve the demanding performance required for Passivhaus certification.
Large apartment developments present unique challenges, from maintaining a continuous airtight layer across hundreds of structural junctions and service penetrations to coordinating multiple trades on site. Early collaboration, robust system design and consistent installation were key to delivering the required performance👏🏻
The project utilised Partel's high-performance airtightness and weatherproofing systems, including IZOPERM PLUS, CONEXO MULTISEAL, VERBOND, and EXOPERM Mono 250 SA, helping create durable, energy-efficient building envelopes designed for long-term performance🙌🏻
Seven Mills is an excellent example of how collaboration, technical expertise and innovative building envelope solutions can help deliver sustainable communities at scale.
