OSBLOCK is the first St-Henri-de-Taillon company in Saguenay–Lac-Saint-Jean to join the AQMAT membership.

Founded in 2015 by entrepreneur and builder Marco Tremblay, the company employs 10 people who manufacture insulated structural blocks, a system for erecting walls piece by piece.

OSBLOCK was invented to provide a different solution to traditional construction techniques by offering a modular and structural product allowing simple and quick installation of walls while offering high energy efficiency and solidity.
