ECONOMICAL WALL SANDWICH PANEL
PIR LIGHT sandwich panel with rigid polyurethane core is coated in steel cladding. It guarantees thermal stability (aging lambda at 0.022 W/mK) with thinner panels. The ” Cold storage joint” (labyrinth joint) used makes the panels maintain the highest tightness and continuity of thermal insulation.
The panel is capillary-inactive and practically non-absorbent. It is a perfect solution for those who need a wall sandwich panel, retaining all its qualities as an external cladding, including a good insulator, but in an economical version.
Its huge advantage is lightness – comparable to boards with a polystyrene core. At the same time, PIR Light provides better thermal conductivity when using a thinner version of the panel (60 instead of 100 mm).
