PIR LIGHT sandwich panel (polyurethane core) with labyrinth joint
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).
PIR LIGHT sandwich panels are characterized by:
- stability of thermal parameters – with aging lambda at 0.022 W/mK;
- great resistance to soaking and capillary inactivity (no water rising);
- lightness make the panels an excellent alternative to those with a polystyrene core;
- the economical solution while maintaining the most important functions of a PIR sandwich panel;
- highly resistant to mold and fungal infestation, and even nesting by vermin (insects, rodents, or birds).
