Wraptite - Barn Conversion

The design and transformation of a derelict barn into a thermally efficient house and home for its new owners is being achieved thanks to the Wraptite system from the A. Proctor Group. South Park Farm Barn, near Ludgershall on the Hampshire – Wiltshire border, dates back to around the 1830s. Self-builders Ian and Casie McDonald Wood are converting this tumble-down barn into their dream home.

Designed to cost effectively replace traditional airtightness methods, Wraptite is a low-resistance vapour permeable air barrier, which is durable, flexible and lightweight, allowing for easy installation, with the added benefit of providing temporary protection against the elements during construction.

Wraptite-SA, the only self-adhering vapour permeable air barrier certified by the BBA, was installed as part of the construction of the roof, with the combination of Wraptite and Wraptite Tape applied to the walls. The use of the Wraptite system will significantly enhance the building’s thermal performance by preventing lateral air movement. It also provides high vapour permeability in a continuously sealed, airtight membrane.

Wraptite Tape was selected because it is not only an effective airtight barrier, but because its high vapour permeability allows damp sheathing to dry quickly, and moisture vapour to escape. Thus ensuring good indoor air quality and reducing the likelihood of mould, mildew, condensation, timber distortion and metal corrosion. The rainscreen cladding, insulation and Wraptite Tape was installed by contractors Midas Cladding as the second school in the refurbishment programme for Durham Direct Services, with more schools to follow bringing the buildings in the county to a higher standard of performance.

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.
