Wood Framing

Traditional wood framing has been the industry standard for residential construction for more years than have been recorded in history. Standard wood framing techniques utilize various size timbers ranging in size from 2"x4", 2"x6", 2"x10" and so on. Each piece of milled lumber generally has a grade stamp on it describing it's unique moisture content, species and grade.

Homeowners should pay specific attention to the type of materials they use on any home improvement project. This will insure a lasting and proper end to your hard work.

The three elements illustrated by the grade stamp should be carefully evaluated before you make your purchase. Lets look a little closer at these elements.

Moisture Content

There are two moisture grades including; "S-Dry", which means the lumber has less than 19 percent water weight and "S-Green" which means the lumber has more than 19 percent water weight. Why is this so important you might ask?, well if you use wet lumber it may shrink and cause gaps in your finished project. If you use green lumber try to store it before use so that some of the moisture can evaporate. This will help ensure a better fitting overall project.

Species

The most common species in the Northeastern United States are; Southern Pine, Spruce, Pine, Fir, and Douglas Fir. Each species has a different structural and strength ratio which may be critical to a particular application.

Lumber Grade

Lumber comes in 4 common grades, Select which is generally chosen for appearance, Number 1, Number 2 and Number 3. Number 3 is generally a lesser grade of wood that may contain many knots and imperfections which may effect structural integrity.
