URSA XPS MAIOR S27P IT

The innovative and new generation products made of extruded plastic foam URSA MAIOR are excellent thermal insulators that offer many advantages. Their closed cell structure allows to have a very low thermal conductivity and unique for all thicknesses to give high levels of thermal resistance in low thicknesses. URSA MAIOR also has excellent mechanical properties, with a compressive strength of 300 kPa. This feature combined with low water absorption, makes URSA MAIOR panels an excellent choice for thermal insulation at the top of flat roofs (inverted roof) hot roof with bitumen membrane or synthetic membrane, garden roof; perimeter walls; underfloor; underfloor radiant.
