va-Q-vip

Details

va-Q-vip is an evacuated micro porous thermal insulating panel with excellent insulating properties. The core material of va-Q-vip is fumed Silica board and non-combustible. It is sealed into a high gas barrier film under vacuum.

Due to the special “edge fold technique va-Q-seam”, va-Q-vip has  smooth faces and sharp rectangular edges so that individual va-Q-vips can be tightly fitted together, making an almost seamless assembly possible. In general va-Q-vip is produced in rectangular shapes. It is also available on request in other shapes such as triangle, trapezium, corner cut and oval cut.

VIP FAQ

Space saving and energy efficient VIPs

What are VIPs?

VIPs – or vacuum insulation panels – are flat panels for optimised temperature insulation that are based on the principle of the thermos flask. These panels offer unrivaled heat insulation at minimum thickness.

What are VIPs made of?

The pressure-resistant core material consists of a compressed plate of micro-porous powder. The core is evacuated and sealed in a high-barrier film using a special technique. The specialist foil used in the manufacture of VIPs also offers protection against air or water intrusion.

What can VIPs do?

VIPs offer ten times higher thermal insulation than traditional insulation materials of the same thickness. Example: 2 cm of VIP insulation will replace 20 cm of fibre or foam insulation. VIPs also offer a service life of up to 50 years. Fridges equipped with our VIPs use up to 50% less electricity, and containers with VIPs provide up to five days of constant temperature for heat or cold-sensitive cargo – without any external power supply. Using VIPs in new building construction or in refurbishment will significantly reduce heating costs and therefore improve the carbon footprint.

Where are VIPs used?

VIPs are used wherever precise heat insulation is required but the available space is limited. The innovative and eco-friendly VIPs by va-Q-tec AG are used in thermal packaging for the pharmaceutical sector, in fridges and freezers, buildings, technology and industry, and in the automotive and aviation sectors.

Lifetime of VIPs

The life time of vacuum insulation panels depends on the characteristics of the film, the size of the pores of the core materials and on the thickness of the panel.

The film of the VIPs drastically reduces the transmission of water vapour and air. A good barrier against penetrating gases is an aluminium laminated film. This however causes heat leaks at the VIP edge and thus is only suitable for large vacuum insulation panels.

Metallized film, i.e. a very thin Al-layer within a high barrier film avoids these heat bridges. Micro-porous Silica has the smallest pore size.: smaller than 0.5 µm. Thus the thermal conduction of air is partially suppressed even at ambient gas pressures.: At a gas pressure of 100 mbar the thermal conductivity of a Silica VIP is only 0.007 W/mK. A totally aired (1000 mbar) va-Q-vip has a thermal conductivity of 0.020 W/mK, which is the worst case.

Increase of Gas Pressure

Long term investigations with 20 mm thick micro-porous Silica VIPs, which were wrapped into a metallized high barrier film, show that the gas pressure at ambient temperatures does not rise more than 1 mbar per year.(see Fig. 3)

That means the increase of the gas pressure after 50 years is about 50 mbar. This corresponds to a rise of the thermal conductivity to a maximum of 0.008 W/mK. That means, that the life time of a 20 mm thick VIP can be up to 30 years. A dry ambient condition for the VIP is very important, because high humidity can influence the film of VIPs.

Accordingly the life time of a 10mm VIP is reduced to half the time compared with a 20 mm VIP. For 40 mm VIPs the life time is doubled.

Quality Control of Film

For quality control and development of advanced products it is not only necessary to know the actual gas pressure within the VIP but it is also important to measure the change of gas pressure.

Previous measurements took a long time to get reliable results. Therefore va-Q-tec has developed several methods which allow to obtain information on the increase of gas pressure within a short time and thus to perform accelerated ageing tests.

In even a shorter time it is possible to reduce the increase of gas pressure by accurate thermal conductivity measurements of a VIP-sample containing a special core material. From the known relation between the thermal conductivity and the gas pressure of the core material the gas pressure increase can be calculated. An example with VIP containing a special core material and wrapped in a metallized film cover is shown in Fig. 4. Here the measurement took just one day and a clear increase of thermal conductivity, which is proportional to the increase of gas pressure, can be seen.

These methods help va-Q-tec to control the barrier properties of delivered films, the gas pressure of any produced VIP and to develop new kinds of vacuum insulation products.

Installation Guidance

Installation Guidance – Vacuum Insulated Panels 

Va-Q-tec vacuum insulation panels are highly efficient thermal insulation materials. The extremely good insulation performance is based essentially on the suppression of the thermal conduction of the air inside the panels due to evacuation. The va-Q-vip B/F have general building material approval under the number Z-23.11-1658 in Germany. The core itself is seemed non-combustible (European Fire class A1). The wrapping is classified as inflammable according to construction materials class DIN 4102-B2.

Vacuum insulation panels in general need to be treated carefully. In the further processing and installation of the products, the following points must be noted in particular:

  • The vacuum insulation panels (VIPs) must not be mechanically damaged. Sawing, cutting, drilling and scratching in particular must be avoided.
  • The surface to which the VIPs are applied must be smooth, flat and free of edges and burrs.
  • The VIPs must not be exposed to high temperatures, high humidity levels and/or aggressive gases during storage or application. Persistent humidity levels above 60% relative humidity and temperatures above 50 °C in particular should be avoided.
  • Please note that thermal bridges occur to a much greater extent in VIP constructions than in constructions using conventional insulation materials. Since humidity in particular can condense at cold spot, corresponding vapour barriers must be used in constructions with VIPs. Vapour barriers can also minimise the risk of condensation on the panels.
  • During installation and use of VIPs, they must not be subjected to any, or if unavoidable only minor mechanical stresses. Point loads and persistent vibration or tension to the wrapping must be avoided.
  • In constructions with VIPs, care must be taken to ensure that they are subjected only to even, full-surface pressure loading.
  • The VIPs must be protected against tensile and shear forces. This can be achieved for example, by ensuring that the structural strength in a construction using VIPs is provided by other measures, and the VIPs are only required to function as thermal insulation.
  • Adhesive fixing of the VIPs can be carried out using 2-components polyurethane adhesive or hot-melt. Foaming with polyurethane foams is also possible. In all cases, care must be taken to ensure that the temperatures occurring during these processes do not exceed 100 °C. A test is advisable, and required, in individual cases.
  • High temperatures and high humidity can degrade the service life of VIPs  as can low temperatures and high humidity. Condensed water in particular should be avoided to the panel surfaces. During the installation of the panels, make sure that no moisture is present, for example from rain. Alkaline, aqueous adhesives may not be used for the installation of the panels. Dispersion adhesives and (two-component) PU foam are very well suited for the adhesion of VIPs.
  • It must be ensured that persons working with VIPs are adequately trained in advance. Fitting and working instructions in particular should be explained with regard to the individual application.
  • VIPs should be placed in such a way that the integrity of the overall application is not put at any risk.
  • The VIPs must also be adequately protected against damage during the usage phase, e.g. by fitting of an outer shell.
  • When installing in floor systems, avoid walking on unprotected VIPs.
