Information @ a Glance

  • Vacuum Insulation was first invented by Sir James Dewar in 1892 it has been used for insulating everything from sub-cooled liquid helium at near absolute zero to hot coffee in a Thermos bottle.

  • The Performance and economic advantages of vacuum insulation have been realized in many industries and applications for decades.

  • It is an advanced thermal insulation technology that significantly outperforms conventional materials such as foam or fiber.

  • There are two different ways to design a building component using the principles of vacuum insulation: on the one hand the load bearing vacuum insulating sandwiches with its envelope made of stainless steel and on the other hand the vacuum isolation panels with its envelope made of a multilayer film.

  • Component for producing vacuum insulation systems comprising at least one insulation layer which is surrounded by a casing, wherein the gas pressure in the insulation layer can be reduced by means provided in the component, wherein the means for reducing the gas pressure is embodified as activatable.

  • Important property of vacuum insulating elements used in building constructions is its resistance against mechanical loads and impacts.

  • Prefabricated vacuum insulated piping has been used for nearly 50years in critical applications for transferring liquid helium, liquid hydrogen and many other cryogenic liquefied gases.

  • Core material used in the construction of vacuum insulation panel plays a very important role in the thermal performance, mechanical properties. Commonly used materials are precipitated silica and nanogel.

  • Vacuum panel insulation, whose insulating properties are superior to polyurethane foam, would greatly reduce heat transfer in storage water heaters.

  • Vacuum insulations are a promising solution for small thermal long-term storage.The performance of vacuum insulation is known not to be much affected by the cryogenic cooling.

  • The thermal insulation system called vacuum insulation panel (VIP) is a very promising technology to decrease the energy used for buildings, heating and cooling.

  • Vacuum insulation has a thermal resistance about eight times higher than the same thickness of traditional fibrous insulation.

  • A Vacuum insulation panel is made by a micro or Nano-porous core material in a vacuumized environment retained by a barrier with low permeability.

  • Benefits of Vacuum Insulation produces particularly high 'R' values, low self weight and eccentricities, good environmental credentials in terms of materials usage, possible improvements in acoustic performance.

  • The use of vacuum insulation can reduce the wall thickness by about 50%.Vacuum insulation is a high efficient but also expensive material for the thermal insulation of the building envelope.
