V delu je podana analiza pravokotnega prehajanja toplote preko plošče, sestavljene iz dveh tankih kovinskih sten, ki sta podprti z diskretnimi podporami. Nastala reža je evakuirana do srednjega ...vakuuma. Podpore so debelini stene in atmosferskem tlaku prilagojene tako, da predstavljajo pravokotnemu toplotnemu toku čim večji upor, prečno pa za pretok plina med črpanjem ne predstavljajo znatne ovire. V delu sta raziskani dve skupini vprašanj, ki v medsebojni povezavi po literaturnih virih slabo obdelani. Spodnja meja pravokotnega prehoda toplote preko take strukture, določenega z vsemi tremi mehanizmi prenosa toplote: prevajanjem po trdni snovi, sevanjem in prevajanjem plina. Določitev najprimernejših materialov in postopkov, ki omogočajo pripravo stabilnega izolativnega vakuuma za najmanj deset let, kar je osnova za morebitno praktično uporabnost.
