Combating Roof-Deck Failures 



THE economy of creosoted 

 wood for roof deck construc- 

 tion wherever abnormal humidi- 

 ties prevail, is strikingly shown by 

 the recent experience of a large 

 plate glass manufacturer. 



The roof-deck of the glass 

 factory was reinforced concrete. 

 Shortly after operations were be- 

 gun in the plant, it was discovered 

 that humidity was causing the 

 cement ceiling to disintegrate. Chips of cement fell 

 from the ceiling of the polishing room, doing serious 

 damage to glass undergoing the finishing process. 



To cure this condition it was necessary to sheath the roof- 

 deck an area of over 200,000 square feet. The sheathing 

 (i"x6" boards) and the stringers (2"x4" scantling) were 

 cut to size, treated with Carbosota Liquid Creosote Oil, assem- 

 bled into sections and the sections bolted to the trusses. This 

 has proved a very satisfactory solution of the difficulty. 



But if, in the first place, the 

 roof-deck had been built of car- 

 bosoted lumber of proper thick- 

 ness, much of the construction cost 

 would have been saved, and the 

 loss in the polishing room caused 

 by falling cement, would have 

 been entirely avoided. 



As wood causes minimum con- 

 densation, it is the most satisfac- 

 tory structural material wherever 

 excessive humidities exist. When the lumber is pro- 

 tected from decay by preservative treatment, it be- 

 comes also the most durable and most economical 

 material that can be used. This applies with special 

 emphasis to paper, textile, starch and copper stamp 

 mills. 



Carbosota Liquid Creosote Oil is the standard zvood 

 preservative for all non-pressure treatments.

(Green tvood cannot be effectively creosoted by non-press- 

 ure processes. It should be seasoned. All framing, drill- 

 ing of bolt holes, etc. should be completed before treatment. 

 If this is impossible, two brush coats of Carbosota should 

 be applied to all untreated surfaces exposed by subsequent 

 cutting or drilling.)
