cellar sash sizes. A window is designated by the size of the 

 glass used in its make-up. If a check-rail window is used, 

 the minimum number of lights of glass is two, and it would 



be designated as "26 X 

 30, 2 -light check-rail 

 window. ' ' If the make- 

 up uses small panes of 

 glass, the designation 

 includes the size of the 

 panes and the number. 

 A window frame is 

 made to accommodate 

 the sash. It is always 

 cheaper to specify win- 

 dow sash which are 

 known as stock sizes. 

 They are proportion- 

 ately cheaper and can 

 usually be obtained 

 from warehouse stock. 

 Doors. Doors are 

 stocked in i>6-inch, i^i- 

 inch, and i^-inch 

 thickness. They are 

 made up solid and 

 veneered. A well-made 

 veneered door is better 

 than a solid one. Prac-

tically all of the hardwood doors, including birch, are veneered. 

 For an outside door, in a house, it is the best policy to use 

 one that is finished on both sides with the same veneer stock, 

 although it may not always agree with preconceived ideas 

 of finish. The outside door is subject to extremes of tem- 

 perature, and the characteristics of two different woods on 

 two sides of a door panel often result in a warped or 

 cracked panel.
