Customised open insert

The open fireplace insert, our original creation, the one that started our story…

So that you no longer find yourself between two fires, performance on the one hand and the charm of a beautiful blaze on the other, we have designed the open insert. Placed directly in the open fireplace, it allows the smoke to be re-burned during the combustion of the wood. Pollutants are thus eliminated, combustion is improved and the heat is better distributed.
