Window sill cutting thanks
to ThermoPosa system

By cutting the marble and producing a discontinuity, the problem of temperature exchange between the inside and outside of the house caused by the passing windowsills can be solved. Unfortunately, cutting with traditional equipment generates a lot of dust that causes much discomfort especially for tenants. To solve the problem we use a special machine for cutting the sill that works without producing any kind of dust. Its secret lies in the telescopic fairing that surrounds the cutting discs and remains adherent even during the insertion of the blades in the marble. Special diamond blades are able to make precise cuts quickly.
