NO FLYING GLASS

BRITAIN’S RAID PRECAUTIONS

Alter losing millions of panes of glass in air raids, Britain now knows almost everything there is to be known about keeping glass from scat tering. Although nothing will prevent 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 out--ICThe task which the scientists of the British Government’s Building Research Station sei themselves was to find materials not in demand lor moi e urgent war needs which woula suck firmly to glass and remain effective for a reasonable length oi time, aims which-apply equally to . any other country likely to suffer air attack. Many popular remedies have been rejected as worthless in these tests, including most of the liquid treatments arid also the crosswire and pad contraption of which so many were soid in Britain to shops and stores early in the war. Strips of adhesive cloth tape or cellulose film though of less value than treatment covering the whole surface are reasonably effective if they are closely spaced; but paper strips are no use unless a really stout paper is used. Research tests have however, brought to light a usefiil 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.
