Energy efficient curtain construction :
heat and humidity are reflected away
and separated from cold by innovative
fabric with high thermal efficiency :
K = 2 W/m2/°C.
>> Active insulation technology
- Multi-reflective thermal insulation =
heat from outside is reflected back outside
= cold generated within the cold
room is reflected back inside.
