One of the most important components of vacuum insulation is the barrier film. The function of the barrier and associated heat seals is to slow the increase in panel internal pressure which is directly related to the panel’s thermal performance. A better barrier opens up markets that require slower decrease in performance (longer life) and potentially high temperature applications.

We have always used the best available barrier.  During the last few years we studied all available world research on barrier film technology.  The technology to produce improved vacuum insulation barriers is increasing every day. We have now developed what we consider the world’s best barrier for vacuum insulation panels. We expect that our barrier performance will significantly improve over the next few years. Also the abuse resistance of the barriers in development will improve. The better barriers will result in opening new markets and expanding existing markets.

Also crucial to the development of a new improved barrier film, we developed a test that can measure the changes in very high performance barriers.
