A construction process certified by the CSTB

The Centre Scientifique et Technique du Bâtiment (scientific and technical building centre – CSTB) is an industrial and commercial public body under the joint aegis of the ministry of housing and urban affairs and the ministry of ecology, energy, sustainable development and planning.
The remit of the CSTB covers scientific and technical research and expertise for the construction and housing sector.

On application, the CSTB assesses new materials or techniques and issues authoritative opinions on the subject.

In 2006, after three years of research, the CSTB issued technical opinion no. 2/06-1205 on the entire building process of Yves Cougnaud.
This opinion underlined the company’s technical skill for the entire production.
New certifications are pending.
