Clay Building Products Facts-n-Figures

Welcome to RGJ International SA

* Clay can conserve half-timbered constructions naturally by absorbing water and thus not allowing wood to collect moisture.

* Clay guarantees a healthy indoor climate with a relative humidity of 45 to 55 %. It absorbs high quantities of water vapour and releases it when the surrounding air becomes too dry.

* Clay products are convenient to use and entirely free of pollutants.

* Only a low amount of energy is used for the production of building materials made of clay.

* Our clay building panels & blocks are easy to lay, bore and screw.
