NO FLYING GLASS

FROM BRITAIN'S WINDOWS DUR-

ING AIR ATTACKS

After losing millions of panes of glass in air raids, Britain now knows almost everything there is to be known about keeping glass from scattering. Although nothing will jirevenE window glass from being broken by blast, it can be so bound together that .splinters from it do not fly about and injure people either inside the bombed building or in the streets outside. The task which the scientists of tlie British Government's Building Research Station set themselves was to Find materials nut in demand fnr| more urgent war needs which weuld stick firmly to glass and remain effective fur a reasonable length of time, aim> whieh apply equally lo an}' other count it likely to sutler air attacks. Many popular remedies have been rejected as worthless in the.»e tests, including most of the liquid treatments and also the ltu.ss-wj re and pad -contraption of which so many were sold in Britain to shops and stores early in the war. Strips of adhesive cloth cape or cellulose film though of less value than treatment covering the whole surface are reasonably eiTcctive if they arc clo-sely spaced; but paper strips arc no xise unless a really stout pape* is us-eu. Research tests have however brought to light a useful range of materials. They showed two classes to be of value —transparent cellulose sheets and textile netting. Both of these, when stuck all over a glass pane, effectively prevent splinters from - flying.
