IsoHemp x Saint-Astier: joining forces of lime and hemp to build differently.
Two independent companies, two stories of passion, technical expertise, and common sense — with one shared ambition: to make bio-based materials a market standard.
IsoHemp and Saint-Astier officially announced their commercial partnership for the French market with great enthusiasm during the Cultural Heritage Fair in Paris on Thursday, October 23, 2025.
The goal?
To make lime and hemp solutions clearer, more accessible, and more consistent for everyone in France who wants to build differently.
Because our expertise is complementary.
Because we share the same vision: to build sustainably, with healthy, responsible, and authentic materials.
An alliance serving the French building sector
Thanks to this partnership, more than 30 people will carry this shared ambition from January 2026 onward.
Teams close to the field, attentive and driven by the same motivation: to advance the eco-materials sector in France, supporting building professionals and everyone choosing more virtuous renovation practices.
