Following the construction of a new Maison Relais childcare centre with a sports hall in Bettembourg, the CBL finishing department carried out the facade insulation with different thicknesses (22 to 30 cm) of rock wool over more than 4,000 m². A roughcast render was subsequently applied, paying particular attention to the areas surrounding the windows. A specific profile avoids any cracks caused by protruding contours.
