Product Description:

Vokes® VIP (Vacuum insulation panels)


Vokes® VIP is an evacuated micro porous thermal insulating panel

with excellent insulating properties. Vokes® VIP 

The core material of Vokes® VIP is fumed

Silica board and noncombustible. It is sealed into a high gas barrier

film under vacuum. Vokes® VIP 


Vokes® VIP is specially developed for insulation applications where

not much space is available but a high thermal resistance is necessary.

Vokes® VIP 

Vokes® VIP is a successful insulation element in the following areas:

• Building appl ication (Roofs, floors, etc)

• Thermal packaging (Medicine trnasport boxes, etc.)

• Appliance (Water boiler, etc.)

• Automotive (train, ship, air plains, etc.)


• Drastically reduced heat fluxes

• Drastically reduced insulation thickness

• Increased usable volume

• All purpose VIP with a long service life
