ROOFING TIN 



was first specified, it was the only satisfactory 

 roofing material on the market ; it met the needs 

 of the building public and that meant popularity. 

 To-day MF is held in just as high favor — it is 

 the symbol of all that is good in roof coverings, 

 and it is a perfect representative of all that is good 

 and best in the materials used for making roofing 

 tin. The process is identical with that used eighty 

 years ago, and if you would like to know exactly 

 how MF Tin has always been made, send for our 

 booklet 'From Underfoot to Overhead"; you 

 will be interested in the methods and the results.

them to any desired height. The wool should 

 be put in place before plastering, and it will 

 be found the most economical to do this when 

 the lathing is done. The lath is plastered 

 underneath, as usual. Mineral wool is soft 

 and pliable, and the plaster forms a perfect 

 key when applied after the wool is placed. 

 This material is entirely non-combustible, and 

 no degree of heat possible in a burning build- 

 ing will consume it. The plan of construction 

 here illustrated and described will make a 

 structure practically fireproof. This form of 

 construction also thoroughly deafens the floor 

 and ceiling, so that sound will not pass through 

 them. By placing the wool on the ceiling, the 

 floors are deafened better than by any other 

 process, as the ceiling is disconnected from the 

 joists, and the deafening material is under the 

 same. The form of construction can be still 

 further carried out and improved by laying 

 a rough floor on top of the joists and stripping 

 them, and placing mineral wool between the 

 strips the thickness of the latter, and then 

 laying the finished floor. The wool in the 

 ceiling will prevent a fire reaching the joists 

 or open space between them from below, and 

 the wool in the floors will stop a fire from 

 burning down from above. The United 

 States Mineral Wool Company, No. 143 

 Liberty Street, New York, N. Y., manufac- 

 tures the material. The use of it in floors, 

 walls, partitions and roofs, for apartment 

 houses, flats, dwellings and general buildings, 

 is very fully treated in an illustrated brochure 

 issued by the firm, under the title, " The Uses 

 of Mineral Wool in Architecture," and is sent 

 on the application of any one interested in the 

 fiber. 



Silica-Graphite Paint 



THE expense and annoyance of frequent 

 repainting can be avoided by the use 

 of a coating of flake graphite and 

 silica for pigments, and boiled linseed oil for 

 a binder. A product of this nature has certain 

 economical features over the ordinary paints, 

 in that the flake graphite is a lubricant, and in 

 its use as a pigment the paint is brushed on 

 with great ease, saving materially in cost of 

 labor and brushes, and giving a covering 

 power of five to six hundred square feet to 

 the gallon. It is known to have given a 

 service of seven years on the iron-covered 

 elevator building of the Kentucky Public 

 Elevator Co., Louisville, Ky. ; eleven years' 

 protection without repainting on the one mile, 

 four track wide steel elevated structure of the 

 Pennsylvania Railroad Co., Jersey City, N. J., 

 and five years on the one hundred and fifty 

 feet steel smoke stack of the Columbus-Edison 

 Electric Light Co., Columbus, Ohio. This 

 paint is famous for its use on many of the 

 most important and most extensive construc- 

 tions in this country. The great piers at 

 Hoboken, N. J., nine hundred feet long and 

 ninety feet wide, where the paint covers all 

 structural steelwork, column jackets and 

 doors. It preserves the structural steelwork 

 of the grand St. Regis Hotel, New York; the 

 Government buildings at Annapolis ; the Wa- 

 bash Railroad Terminal, Pittsburg; the 

 Trinity Building, New York; the Lafayette 

 Hotel, Buffalo, and the great " Hot Metal 

 Bridge," Union Railroad, Pittsburg. It is 

 also remarkable for its adoption by owners 

 of buildings and constructions of the lesser 

 sort, such as dairy and farmhouses, small 

 stations, shops and dwellings. Graphite paint 

 meets fully all the requirements of preserva- 

 tion. The graphite is a natural product mined 

 by the Dixon Company at Ticonderoga, 

 N. Y., and is the only pigment of its kind 

 known to exist. It assumes the flake form in 

 its physical structure, and from this fact alone,
