HC Deb 01 August 1940 vol 363 c1392
67. Mr. Simmonds

asked the Home Secretary which method of glass protection in air raids has been found in the course of recent hostilities to be the most efficacious?

Sir J. Anderson

Recent experience confirms the view of my technical advisers that textile netting, transparent film affixed to the whole surface, and strips of adhesive tape or other strong material give the best protection.

Sir Francis Fremantle

Does that mean a combination of these methods?

Sir William Davison

How thickly should the adhesive tape be applied?
