The Wraptite® external air barrier system from A. Proctor Group has been
selected as part of a new zero carbon affordable homes project at New Ferry on
The project at Windsor Close in New Ferry is a new development of three bedroomed terraced houses to be constructed by Property Development Group Starship at its off-site manufacturing facility in Deeside.
The superior airtightness performance of the Wraptite membrane from the A. Proctor Group is the perfect solution, delivering significant benefits to the combination of in-factory manufacture and on-site housing construction.
Karl Ventre, Director at Starship, explains why Wraptite was chosen to achieve the airtightness solution and how it benefits off-site construction. “We have specified this product within our system offering for the last three years, and it has always performed well and helped contribute to good airtightness test results.
The self-adhesive membrane is easily applied in the factory, bonded externally to the substrate, and ensures that the membrane is held firmly in place, even during transportation, maintaining the quality of the system from installation to build and completion. Wraptite is an excellent quality product, and the self-adhesive backing gives a very neat finish.
The technical team at the A. Proctor Group supported us throughout and provided comprehensive condensation risk analysis reports at the outset.
The spacious 1,200 sqft homes offer the lowest running costs of any property in the immediate area and deliver more affordable living for local people. These Carbon Zero homes provide over 105m2 of modern, affordable living space and were installed in seven days, ready for internal fit-out.
Starship’s unique panelised model means that a new home can be delivered and installed anywhere a refuse collection vehicle can fit, with no special arrangements or unnecessary disruption to the community.”
The Wraptite air barrier system offers a safer and simplified membrane system. It is a fully self-adhered vapour permeable air barrier certified by the BBA.

For any building to have an energy efficient, healthy, moisture free building envelope there is a clear need to manage the balance of Heat, Air and Moisture movement (HAMM) throughout the building’s life cycle from design, construction, completion and use.
