Isoltech

Isoltech is an Italian company specializing in technology, machinery, and additives for producing cellular concrete. Established in 1987, it was one of the first companies in Italy to introduce systems for making cellular concrete with specialized machines and foaming agents. In July 2025, the French building materials giant Saint-Gobain acquired Isoltech to strengthen its construction chemicals business.

The company's business model is centered on providing an integrated and customized service that transfers the know-how for autonomous cellular concrete production. This approach goes beyond selling products to establish long-term partnerships with clients, including installers, contractors, designers, block producers, and prefabricators. Isoltech serves the ready-mix concrete, precast, and screed markets. Its revenue is generated from the sale of technology, machinery, turnkey plants, and various additives.

Isoltech's core offering is a complete system for producing cellular concrete, a lightweight, insulating, and economical material made by mixing water, cement, and sometimes sand with a foam. The product line includes customizable mobile and stationary plants, foaming agents (plant-based, protein-based, and high-performance synthetics), auxiliary additives, and complementary products. The technology allows for the production of cellular concrete with varying densities for different applications, such as flooring subfloors, geotechnical fillings, masonry blocks, and prefabricated panels. The firm also holds patents for eco-compatible technologies, like Hi-Tech Isocem S/X, which uses industrial waste or second-life raw materials.
