How do you frame a 2×4 corner?

A 2×4 Corner Framing Tutorial:

The following are some basic tips that will help you to frame your corner properly. You may have heard the term “2×4” before but it does not mean exactly what you think it means. A 2×4 is actually a 4-sided lumber which consists of 2 x 8’s or 3 x 12’s. The reason why it is called a 2×4 is because the width of each side of the board varies from 1/8″ to 3/16″ depending upon its thickness.

There are many different types of 2×4 lumber available such as Douglas Fir, Pine, Hemlock, Redwood, Spruce and others. Each type has its own characteristics when it comes to strength and other qualities.

When framing a 2×4 corner, there are certain rules that must be followed. These rules are based on the type of wood used in the lumber. The most common types of 2×4 lumber are:

1) Douglas Fir – Strongest and best looking 2×4; very strong and durable. Can withstand high temperatures without cracking due to its toughness. It is also one of the easiest woods to work with since it has no knots or cracks in it. For example, the Douglas Fir is stronger than the Hemlock but less flexible than the Pine.

When you purchase 2×4 lumber it is best to buy only one kind at a time so that you get the most out of your money. Also, make sure that all of your lumber comes from a reputable source since there are reports of illegal timber being sold on the Internet. If possible try to avoid buying any wood from China where they often use inferior materials and workmanship.

2) Southern Yellow Pine – A softer wood than Douglas Fir. It is slightly weaker and not as strong or durable as other types of wood. It is usually knotty and more susceptible to damage from insects. However, it is still a good wood to use and can be found at a reasonable price.

3) Western Hemlock – One of the worst types of woods to use due to its weak adhesive properties.

2) Spruce – One of the lightest and weakest, this lumber is brittle, weak and splinters very easily. This wood is generally only used for utility purposes behind walls or in attics.

3) Redwood – Heavier and slightly stronger than the spruce, it is still brittle but can be used in some areas if you are on a budget. It is definitely not a good idea to use this wood in load bearing walls since it will snap very easily.

4) Cedar – The good thing about cedar is that it has natural anti-fungus and anti-termite properties. These properties help to deter these problems from growing in your home. In addition, the wood itself is very flexible and resistant to decay from wet conditions.

5) White Wood – This wood has a tendency to split and crack when nailed. It also tends to absorb water and split when in contact with it. The wood splits easily and you would be wise to avoid using this type of wood to frame a corner.

4) Spruce – Commonly used in the construction industry, Spruce is a cheap and fairly good wood. It is slightly softer than redwood or cedar, but it still holds up well against moisture. It has no special qualities that make it better than other woods. However, it usually isn’t as expensive as most other woods.

5) Redwood – The most expensive and exotic hardwood available. It is very durable, flexible and resistant to damage from both insects and moisture. It is often used for outdoor decking because of these qualities. However, it is very heavy and not usually a good idea to use in the house because of this factor. If you use redwood, make sure you stay away from the softish “split-log” sections and use only clear or knot free pieces.

It is usually best to stay away from these woods when constructing your home since they are much more expensive and less durable.
