Live as Nature

PWall Constructive System

The PWall Constructive System is a modular straw wall for the external infill of buildings consisting of natural and renewable materials such as wood, straw, clay and natural lime. These materials are factory-assembled to form a finished product ready for installation. Thanks to prefabrication, once you placed all the walls, you just have to complete the interior and exterior infill levelling it.

Total cancellation of thermal bridging in the wall

The special structural conformation ensures a 50% saving of energy dissipated in the junctions because of the different materials.

Guaranteed Straw

The straw used is selected and monitored from birth and throughout the assembly process. To obtain a higher quality of the finished product the straw undergoes a mechanized treatment to eliminate any insects and foreign material. Furthermore, we do not use chemicals or products containing formaldehyde throughout the procedure.

Quick Installation

The PWall Constructive System allows to complete the construction of the structure in a few days and with the possibility to arrange the electrical pipes in the factory. The weather conditions as well will no longer be the cause of works stoppage, thanks to the plaster that protects the straw.
