va-Q-plus

Characteristics

 
va-Q-plus is one of our most advanced vacuum insulation panels. It is produced with our new powder technology. The core of va-Q-plus is made of inorganic oxides, up to 80% being fumed silica and the rest IR and a small amount of organic fibres. It is non-combustible. 

Our special powder technique and semi-automatization process assure that va-Q-plus has a very low thermal conductivity, combined with a long service life and excellent price-performance ratio. Due to the production technique used, va-Q-plus has a flange, which can be used as guidence for positioning. The flanges can be refolded with a special treatment upon request.

This core material can be reused and recycled. Varios shapes are possible, for example cylindrical shapes tailored to the needs of our customers. va-Q-plus can only be produced in a series production.

 

Applications

Due to its excellent insulation value and long service life, va-Q-plus can be used anywhere, where little space is available but a high thermal resistance is necessary.
 
  • Packaging/Transport (thermal multiuse boxes and containers, etc.)
  • Automotive (trucks, tank containers, electric cars, etc.)
  • Home appliances (refrigerator, freezer, water boiler, etc.)
  • Construction systems (facade cladding sandwich panels, etc.)
  • Technical devices (scientific machines, etc.)

 

Advantages

    • Great performance ratio
    • Various and flexible shapes available
    • Very long service life
    • Recyclable (core material)

  • Hint:

    (1) The maximal thickness of a panel depends on the size of the panel. The typical thickness is between 8 mm and 30 mm. The smaller the panel, the smaller the maximum thickness. Please contact us for your desired panel dimensions.

    (2) Due to their special manufacturing process, va-Q-plus panels are not ideally rectangular. The thickness at the edge is somewhat less than in the centre. All dimensions, tolerances and insulation values refer to the insulating area from corner to corner.

    Please note: There are between 10 mm and 20 mm seams at all sides of the panel.
