Window Glass

Excerpts from a recent Bulletin of the Millwork Institute of California, by H. T. Didesch, Managing Director.

Machine-made glass in the past 15 years has practically displaced the products of hand-made factories. It reaches its greatest perfection irt the factories of America and todan "domestic" window glass is far superior to any foreign make.

The Master Specification for GLASS for glazing purposes as prepared by the Federal Specification Board of the United States Government, contains the only definite grading rules to be had and classifies clear window glass as follows:

Single Strength

CLEAR 1

IAA Quality lA Quality I ( | Average Weight ,B Quality I lStl oz. per sq. ft.

\C Quality I I

(AA Quality

)[-0;;iiii )A.,e'"geWeight cl.A,ss | (B Quality (

WINDOW I Double Strength) \24% oz. per sq. ft.

I | (Glazing Quality Weights t (Factory Run 34 oz. 39 oz.

I Heavy Sheet I 26 oz. 29 oz.

The total production of window glass from domestic factories, based on the best results obtainable, will grade about as follows:

'

3/o to4% C Quality

65% to 70% B Quality

27% to 34% A Quality

2/o to 3% AA Quality

''"Single Strength" glass runs from t2 to lol lights to the inch and has an average weight of.I8l oz. to the square foot. The maximum dimensions recommended are 40x50 inches. "Double Strength" glass runs from 9 to 8 lights to the inch and has an aveiage weight ot 24l oz. to the square foot.' The maximum dimensions recommehded are 60x80 inches.

European glass is marketed as 16 oz. znd,2l oz. and, ol course, is thinner than domestic glass.

.The weight or thickness of window gtass.has no bqaring on the defects allowed. The size of the sheet governs the extent of defects permissible in both "single" and "double" strength.

There is no such thing 19" plrfe-ct window glass.

Inasmuch as "AA" A,f;,ro::Tllitutes so small a percentage of the total output, it is not available from dealers' stocks, neither is there any certainty of the factories having the stock on hand. Delays are bound to occur, which, with the additional expense of L. C. L. shipments and extra hazards of breakage, make its cost far out of proportion to the results looked for.

In unusually high class residence work and wherever the cost of the glass is of secondary consideration, polished plate should be used, particularly on street elevations, and in all lights having an area greater than 16 square feet. The rear and less conspicuous elevations, as well as smaller lights, may be glazed with "A" Quality, either single or double strength, depending upon their size, with satisfactory results.

If the cost of polished plate (its present cost is 3 to 4 times that of double strength) prevents its use, "A" Quality should be used. Lights having an area of from 5 to 16 square feet'should be "dou-!fe strength." Those under 5 square feet should 'be r"sing{e ''strength," bearing in mind that French doors and large casements which are more or less subjcit to sudden o-pening and closing, should be glazed with "double strength." "' ir

(Continued from Page 55.)

It should be understood that it is almost impossible for the industry to furnish "AA" Quality window glass. Undoubtedly in the past, the promiscuous specifying of "AA" Quality has lead to substitution of 'AA' Quality to a minimum, or better still, to avoid its use altogether.

Bear in mind, please, that your specifications must be reasonably obtainable to be fulfilled.

"AA"

Quality 0"q1";3':Slur'"i#ree f rom defects.

When plate glass cannot be used, office buildings, exclusive apartments and the better class residences and hotels should be glazed with "A" Quality glass,. particularly on the street fronts. The rear, alley and court elevations may be glazed with "8" Quality and the cost materially reduced.

Lights of areas up to6 square feet can be "single strength" (unless there be extra rvind hazard). Those from 6 to 16 square feet should be "double strength."

A saving can be made by using "8" Quality glass in all openings not in the line of direct vision, such as transoms over store fronts, transoms over high windows, borrowed lights, etc.

DS (double strength) glass costs approximately one-third more than single strength. In lights of 6x8 td 18x30 or those of an area of. 3l to 4 square feet, nothing is gained in either effect or service by using DS. In the interests of conservation, schools and other public buildings, in which lights are of this area, should be glazed with SS (single strength) glass.

In. ordinary apartment houses, hotels, dwellings and all medium class structures, "B" Quality should be used, particularly in the service part of the buildings. It is the custom to select the best lights for the lower sash of double hung windows and the more prominent openings, thereby eliminating to a large extent, the defects bccuriing in th-e line of vision.

, "B" Quality glass should be used in loft buildings, warehouses and small dwellings when the size of the lights does not exceed 16 square feet. There will, however, be occasions when it is necessary to use "A" Quality, as on street elevations, in the offices of large buildings, and in living and dining rooms of houses.

"Fourth" Quality and "C" Quality glass is produced in such small quantities that they are not carried in stock in this territory. Their use is confined principally to hot houses, hot bed sash, barn sash, t"tc.

Heavy Window Glass

This glass is produced in trvo qualities-"glazing quality" and "factory run," and in four thicknesses-26 oz., D oz., 34 oz., and 39 oz.

26 oz. runs from 8 to 7l lights to each inch

8 oz. runs from 7 to 6l lights to each inch

34 oz. runs from 6rl to 6 lights to each inch

39 oz. runs from 5l to 5 lights to each inch

The average dimensions obtainable are as follows:

60 x 84 inches for 26 oz. and D oz.

48 x 72 inches for 34 oz. and, 39 oz.

The maximum size recommended by the United States Government Master Specification is 66 x 90.

This glass is made with the same materials and by the same process as "single" and "double" strength rvindow glass. It contains all the defects of. l8l and 24rl oz. glass. Its only comparison with plate glass is in weight and thickriess. fts use is as a substitute for polished plate glass in cheaper grades of rvork, or where an extra heavy glass is required.

Heavy window glass is sometimes referred to as "Crystal Sheet" or "3/L6 inch Crystal." Many have the impression that crystal sheet is similar in quality to plate but lighter in rveight, which is not correct.

The word "Crystal" is a trade name, and a misnomer rvhen used with reference to quality.

Heavy window glass is just rvhat the name indicates. Heavy window glass is not available from stocks on the Pacific Coast and recuirements of it are ordered from the factories, subject to tire same delays as "AA" Quality.

A New Method of Packing

A nelv and unique method of packing lumber products has been adopted by George C. Brown & Company in the packing of their Supercedar Closet Lining.

This company, said to be the largest manufacturer of Aromatic Red Cedar Lumber in the world, and which has within the last two years gone to manufacturing the finished product, is packing their Closet Lining in corrugated fibre board boxes. These boxes are 8% inches in length and a{ter the stock is placed in the boxes, the ends are sealed and the package {astened with three steel straps.

The Sales Department of George C. Brown & Company states that retail dealers all over the country are becoming very enthusiastic over this new systern of packing. The stock can be handled with a great deal less labor, stored in less space, and delivered by the retail yard to the job in the same fresh, clean -condition in which it leaves the mill.

Dealers have suggested that this company has started a system of packing which may eventually be adopted by a great many lines of the lumber trade.

Supercedar Closet Linihg is rvholesaled in Southern California by E.J. Stanton & Son, Los Angeles.

A Cash Prize Competition

"While only one employee in the Redwood Lumber inclustry won a cash prize in the National Waste Prevention Contest ending last spring, for a nerv and practical milling device. the directors of the California Redrvood Association are convinced that there are many more employees in the Redrvood industry rvho have the ability and ingenuity to perfect worth-while devices that prevent waste or reduce manufacturing costs and are entitled to some sort of recognition."
