An impressive new family house in Osaka, Japan is set to benefit from the
superior airtightness performance qualities of Wraptite from the A. Proctor
Group. Designed specifically with the objective of maximising energy
efficiency and minimising its carbon footprint, the house will become home
to two generations of family. The house was designed and built
by Soken Co. Limited based in Osaka.
In consultation with the A. Proctor Group, the client and contractor selected Wraptite high-performance external air barrier system for use within the project. Wraptite is a self-adhesive membrane, which can fully bond to multiple different substrates to provide a continuous, self-adhered and airtight finish.
The unique characteristics of Wraptite provide excellent moisture vapour transmission rates, allowing moisture vapour to escape the building interior, whilst maintaining and ensuring the integrity of the airtight building envelope. Wraptite also prevents lateral air movement, further enhancing the buildings overall thermal performance.
Wraptite was applied externally, quickly and easily, unlike internal air barriers, which can be more complex and costly to install due to the need to accommodate building services such as electrical, lighting, heating and drainage systems.
In the drive for more energy efficient buildings and the need to reduce carbon emissions, Wraptite continues to reassure, both in performance and in ease of application. The only self-adhering vapour permeable air barrier certified by the BBA, Wraptite continues to be the preferred choice for architects and contractors alike.
