\fhat is Modular Design ?

Many lumber dealers have been asking the question "What is modular design ?" Briefly, coordination, the basis of modular planning, may be defined as the dimensioning of building units or components so that they rvill fit together, plus the use of building dimensions consistent rvitl-t such coordinated sizes. It involves:

1. Sizes of building materials and components which permit their field assembly with a minimum of cutting and fitting.

2. Dbtails and plans rvhich shou' the assembly of the above, and

3. Modular planning which correlates building'dimer-rsions with the above sizes and details. A 4-inch unit has been selected as the standard dimensional increment.

In recent months announcements of the adoption of the 4-inch module as basis for product sizes have been made by a number of building material manufacturers, notably the National Door Manufacturers Association, wood windows and doors; the Structural Clay Products Institute, brick and tile ; Concrete Masonry Industry, concrete blocks; Metal Window Institute, metal windows. Glass block manufacturers have always made their product to conform t() the 4-inch module. A number of other manufacturers of building materials are studying and working toward standardization of product dirrensions with the 4-inch module as the basis.

Heretofore no national standard for wood windows and sash has been recognized by the woodwork or building industries. Following the settlement of New England in colonial days, certain window opening sizes came to be recognized in that particular area. As the population moved westward other local or regional standards developed.

As a result the United States has experienced at least ten different local or regional rvindorv and sash standards. This multiplicity of standards has caused some confusion to architects and builders. it did not lend itself to maximum economy in manufacture and distribution.

The 32-page booklet published some time ago by the National Door Manufacturers Association, and which was mail'ed to 2/W retail lumber dealers, and to all sash and door jobbers, gave complete details on the new standards, which represent more than tu'o years of study on the past of the producers of ponderosa pine stock woodwork products.
