HC Deb 07 August 1940 vol 364 c221W
Mr. Parker

asked the Home Secretary whether he will issue an authoritative statement on the value of the various compositions alleged to protect glass windows from blast in view of the large sums being spent on them?

Mr. Mabane

Authoritative statements have been made and I would refer the hon. Member to A.R.P Memorandum No. 12, Part III, paragraph 2 (f) and to the booklet "Air Raids: What you must know, what you must do," page 16.
