Wraptite - Japan

The superior performance of the Wraptite membrane from the A. Proctor Group has been installed to ensure a watertight solution for the roof of a new sports gymnasium in Japan.

In consultation with the A. Proctor Group, the contractor Kotobuki selected the Wraptite high-performance external water-resistant system for use within the project. Wraptite is a self-adhering, airtight, yet vapour permeable barrier, which is fully water-resistant, and can be easily bonded to multiple different substrates to provide a continuous, protective finish to roofs, walls and the entire building envelope.

Product Information

Wraptite was applied externally, quickly and easily, unlike some internal membranes, which can be more complex and costly to install due to the need to accommodate additional trades such as electrical, lighting, and heating systems.

Where a full wall and roof airtight envelope is required Wraptite can be used in both applications. The self-adhered backing not only ensures an airtight seal but resistance at laps against water penetration, dust, air infiltration and wind resistance make it an excellent choice for this 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.

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 building envelope. With an Sd-value of 0.039m, Wraptite’s high vapour permeability allows for construction moisture to dry out, reducing the likelihood of mould, mildew, and condensation related damage such as timber rot and distortion or metal corrosion.
