Eco Membrane for the house

Inaka Home is to become a model house to demonstrate a new ecological high tech membrane, that is used to finish off building insulation on the inside. The name of the product is "intello" manufactured by a company called "proclima" in Germany (see pdf file at bottom of this page). It is a kind of membrane that regulates humidity exchange between the inside and the outside of the house, thereby not only preventing condensation and related mould issues, but also keeping warm in winter (no loss of heat) and cool in summer (reduced air conditioning cost). This product is new in Japan, and is now being actively promoted by Eco Transfer Japan to architects and other builders.

Our home, is of course not completely air tight due to its traditional Japanese construction method, but nevertheless it will help to conserve heating and cooling energy, and demonstrate how such a high tech component greatly enhances other natural building materials, like breathing insulation (wool/recycled cellulose/wood chips) and mud walls.
