Summary

THOUGH LITTLE HAS CHANGED IN THE BREWING PROCESS, THE TECHNICAL EQUIPMENT HAS BEEN IMPROVED CONSIDERABLY. COOLING THE BREW, GIVES ALSO A NEED FOR THERMAL INSULATION. IN THE BEGINNING THERE WAS CORK AS AN INSULATION MATERIAL, FOLLOWED BY CELLULAR PLASTIC FOAM AND FIBROUS INSULANTS IN THE PAST 30 YEARS. ALL THESE MATERIALS GRADUALLY ABSORB WATER, CAUSED BY THE PHENOMENA THAT WATER VAPOUR IN THE AIR TENDS TO GO INTO THE DIRECTION OF THE COLD PIPE SURFACE. IN PRACTICE IT APPEARED TO BE IMPOSSIBLE TO MAKE THE ABOVE INSULATION MATERIALS VAPOURTIGHT. CELLULAR GLASS INSULATION, WELL-KNOWN IN THE PETRO-CHEMICAL INDUSTRY, HAS PROVEN TO BE 100% VAPOURTIGHT, SO AN EXCELLENT CHOICE FOR COLD PIPING AND EQUIPMENT.
