Vacuum insulation panels – microtechnology is the key to innovation
The core structure is responsible for the highly efficient insulating effect of our VACUPOR® vacuum insulation panels. This is insert and based on highly dispersed silica. There is only single point contact between the spherical nanoporous particles. This substantially reduces the thermal conduction due to contact between solid matter. added to this, the micropores minimize thermal transmission by convection. Infrared opacifiers, which have been developed especially for VACUPOR®, significantly reduce the heat transport processes by absorption and reflection of radiation.
The already outstanding insulation properties of the nanoporous insert is further enhanced by placing the completed panel under a virtual perfect vaccum.
In this process, the VACUPOR® inserts are encapsulated in multilayer barrier films and sealed under vacuum in a specially patented process.
The evacuation of the material completely prevents thermal transmission by convection.
VACUPOR® vacuum insulation panels (VIP) produced in this way reduce overall thermal transmission to a quarter of its initial value.
As a result, it is possible to achieve a significantly higher efficiency than with conventional insulation materials such as mineral fibers, foams or PIR insulation panels.
The thermal insulation value is < 0.005 W/m*K (measured at 22.5°C average temperature) and the technical approval by the German Institute for Building Technology (DibT) for our product VACUPOR® NT-B2 quotes a rated value of 0.007 W/m*K. This means that the panels carry full CE marking and are readily accepted by Building Control bodies
The layer thickness of VACUPOR® VIPs is 4 to 10 times less than that of conventional systems. Weight is reduced by a factor of 2 to 15.
In the construction sector, VACUPOR® VIPs make it possible to obtain very effective results with ultra thin insulation thicknesses and impressively small space requirement.
In existing housing stock, where there is insufficient space to carry out essential high-quality energy efficiency improvements, VACUPOR® VIPs are real problem-solvers.
Esthetic considerations also play a large part today, e.g. in low-energy houses (“passive houses”), where ultra thin wall insulation allows slimmer walls and maximum light access. Vacuum panels are the ideal solution to meet these requirements.
