va-Q-plus

Product catalog summary

Characteristics
va-Q-plus is an advanced vacuum insulation panel produced using new powder technology. The core consists of inorganic oxides, primarily fumed silica, with IR opacifiers and organic fibers. It is non-combustible and features low thermal conductivity, long service life, and a good price-performance ratio. The panels have flanges for positioning, which can be refolded upon request. The core material is recyclable, and various shapes, including cylindrical, are possible. Production is limited to series production.

Applications
va-Q-plus is suitable for applications requiring high thermal resistance in limited space, such as:

Packaging/Transport (thermal multiuse boxes and containers)
Automotive (trucks, tank containers, electric cars)
Home appliances (refrigerators, freezers, water boilers)
Construction systems (facade cladding sandwich panels)
Technical devices (scientific machines)

Advantages
va-Q-plus offers a great performance ratio, flexible shapes, long service life, and recyclability.

Notes
The maximum panel thickness depends on size, with typical thickness between 8 mm and 30 mm. Panels are not ideally rectangular due to manufacturing processes, with edge thickness less than the center. Dimensions, tolerances, and insulation values refer to the insulating area from corner to corner. Seams of 10 mm to 20 mm exist on all sides. Figures are guides and not for specification preparation.
