CORRUGATED IRON AS A BUILDING MATERIAL [To the Editor of
the SPECTATOR.]
Sta,—Your correspondents may be interested to hear some- thing of a comparatively new building material which may be used instead of corrugated iron., I refer to what is known as Ft ibertsOn's Asbestos Protected Metal. This Preduct consists of a steel sheet which L' suFiouPdE by three envelopes, consisting respectively of an asphalt coating, asbestos and, outermost, a thick waterproof covering. This material can claim all the advantages of the usual sheet building materials, such as asbestos or corrugated iron. In addition, it possesses insulating properties which make it especially suitable for use under extreme climatic conditions.
It is also alkali and acid proof to a reasonable degree. An additional advantage is that no painting is required. The price is slightly higher than that of asbestos sheeting. As " A.P.M." can be supplied in several colours and in a number of varieties of corrugation, including mansard, and also in the form of flat sheeting, it is now being used for high- class domestic architecture in America and is also becoming increasingly popular for the construction of Government and industrial buildings, not only in the United States, but throughout Europe and in the Far East. The Scottish Rugby Union stand at Murrayfield has a maroon-coloured roof of this material, and I believe that the new grand-stand at Epsom is another example which is likely to be familiar to readers of the Spectator.
In conclusion may I say that I am in no way connected with the manufacture or sale of this commodity ?—I am, Sir, &c.,
