Performance of sealed evacuated panels as thermal insulation.

Author(s) : BRODT K. H., BART G. C. J.

Type of article: Article, IJR article

Summary

Regulations concerning CFCs require the use of other blowing agents than polyurethane which often do not possess the same low thermal conductivity as, for example, R11. Evacuated panels avoid these environmental problems and can possess lower conductivity than rigid foams. This makes the authors believe that they are a promising option in spite of the major problem of maintaining the vacuum for a decade or longer. They require: a) a leak-free sealing and a covering with an extremely low gas permeability; b) a low and stable inner pressure; and c) an infrared absorbing filler which withstands outside pressure. A parametric study has been done on the influence of materials and dimensions on the performance of evacuated panels.
