Since the beginning of 2012 Profholod company introduced the new technological process and started the production of sandwich panels having the minimum thickness - 40 mm. The characteristics of the panels are the following:
- thickness — 40 mm
- length — up to 6 m
- weight of 1 m2 с with 0,5 mm metal facing — 9,5 kg
Original pack contains 28 panels.
Heat engineering characteristics of a wall made of 40-mm sandwich panels are equivalent to:
- 600-mm thick brick wall.
- 100-mm thick wall of sandwich panels with mineral wool core
