Our Certified Solutions

A Guarantee of Excellence

All our limes and mortars are designed in strict compliance with current product and application standards in the building industry. They are therefore validated by certifying bodies, giving written assurance that a Saint-Astier® product complies with market requirements :

Our limes are standardised under NF EN 459-1 for construction limes.
Our mortars are standardised under the ‘Specification for mortar for masonry NF EN 998-1’ standard.
Moreover, our products are CE marked, i.e. they comply with the safety requirements set out in European directives. Tests and trials are therefore carried out to validate the conformity of the products, enabling them to be distributed throughout Europe.
Saint-Astier® bio-sourced hempcrete solutions comply with the professional rules of hemp construction.

Excell Certification

The EXCELL® and EXCELL® GREEN ZONE certifications represent a higher level of quality by ensuring that the emissions of chemical compounds from certified materials will not cause any deterioration in the products stored, or poor living comfort for occupants thanks to the absence of specific contaminants. They enable all products and materials used in the construction and/or renovation of buildings to be checked for toxicological and organoleptic properties.

They are therefore non-hazardous products as defined in EC regulation no. 1272/2008 or directive 67/548/EEC.

At Saint-Astier®, we make every effort to go beyond just the product standards in force so our partners can be sure of receiving quality products.

VOC A+ Declaration

All mortars in the Saint-Astier® range are classified VOC A+. We take particular care to ensure that our solutions emit little or no volatile organic compounds into the ambient air. A guarantee of safety and well-being for all!

Binders, like lime, are not finished products and therefore cannot be classified as A+. However, if the filler with which they are combined (sand, mineral or vegetable aggregate, etc.) does not contain VOCs, the final product can be considered A+

Volatile organic compounds (VOCs) are a group of substances belonging to different chemical families, all of which evaporate more or less quickly at room temperature. This indoor air pollution is generated by a number of sources, including buildings, the environment and equipment. Building materials and decorative products can emit different types of substances. Faced with this situation, some European countries, including France, are proposing various qualification procedures for construction products, to reduce pollutant emissions at source.
