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.

Restrictions on Applications
The special foil of the TURVAC® vacuum insulation panels must not
be damaged by drilling, cutting, milling, nailing or similar, since the
interior pressure of the panel will rise and the special properties of
the panel, in particular its excellent insulation characteristics, will be
lost.
