CHAPTER V 

 STRUCTURAL MATERIAL 



Practically all the material, whether it be 

 wood or metal, which goes into the construc- 

 tion of a modern greenhouse, is milled or 

 shaped at the factory. It will almost never 

 pay the prospective builder to attempt to 

 use material made by any but specialists in 

 this line of work. There are several such 

 firms in this country. Greenhouse construc- 

 tion, then, so far as the individual builder is 

 concerned, becomes simply a matter of choos- 

 ing the kind of material he desires to use; 

 ordering it from a responsible manufacturer 

 and assembling it or placing it in its proper 

 position. Most greenhouse construction 

 firms have certain standard or stock houses 

 which they ship complete, even including 

 nails, paint and putty if wanted, at a definite 

 stated price; and they will erect them if it is 

 desired. They will also design and build a 

 house or range of houses to suit any given 

 condition.
