The polystyrene cutter from MSW is the optimal hot wire cutting device for insulation, renovations, and building renovations on medium and large objects. It was developed for cutting insulation panels made of Styrofoam, Styrodur, or polystyrene with millimeter precision. With the hot wire cutter, you can easily cut even large insulation panels with a length of up to 1300 mm and a depth of up to 330 mm. The side support prevents large hard foam panels from slipping.
