URSA XPS NVII - L IT

URSA XPS extruded polystyrene products are excellent thermal insulators with many advantages. Their closed cell structure allows for very low thermal conductivity and high levels of thermal insulation. URSA XPS also has excellent mechanical properties, with a compressive strength of 700 kPa. This, combined with low water absorption, makes the URSA XPS an excellent choice for flat-bed, back-to-back garden roof insulation. Also ideal for isolating under industrial floor and underfloor.
