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.
