TURVAC Si™ is a vacuum insulation panel based on fumed silica core material. The core is inserted in high barrier multilayer foil, which contributes to service life up to 60 years.
TURVAC Si™ is mostly used in high performance insulation solutions, where not only high efficiency, but also long time performance is needed. Turvac Si™ lifetime can be 40 – 60 years.
TURVAC Si™ vacuum insulation panels are widely used in:
- household appliances (refrigerators and freezers),
- medical refrigerators and TCP - temperature controlled packaging,
- construction and buildings (thermal bridges insulation, terraces, facades),
- window shutters’ isolation.
