The FramePro W1 air barrier system from the A. Proctor Group has been chosen for a new modular Passivhaus Plus housing project in Cardiff.
The project has been designed by Beattie Passive using its award-winning, patented design and build system, which the company says is the UK’s first certified Passivhaus Complete Build System.
The development consists of 48 one-, two- and three-bed apartments with two ancillary office buildings. Manufactured offsite in the Beattie Passive factory in Norwich, the buildings were transported and assembled on-site in Cardiff.
The FramePro W1 system was chosen as an external air barrier. The system comprises FramePro W1, a low-resistance vapour permeable air barrier for walls, plus Wraptite Tape.
Ron Beattie, Managing Director at Beattie Passive, explained, “FramePro W1 is an excellent barrier system that provides complete protection from ‘windwashing’ and the effects of wind penetration and moisture management in buildings. In addition, the system is easy to use and apply, easy to joint, and won’t tear.”
Another feature of the FramePro W1 system is that applying it externally simplifies the process, maintaining the building’s integrity, as there are fewer building services and structural penetrations to be sealed.
Isabel Beattie, Director at Beattie Passive, commented: “the buildings are designed to achieve Passivhaus Plus standards and zero carbon. To achieve these high standards, we undertake rigorous testing on the materials used in our build system, and the FramePro W1 system now features in all of our buildings.”
