Cedar, a popular wood choice for various applications, often sparks the question: is it hard or soft? The answer isn't a simple "yes" or "no," as different cedar species exhibit varying hardness levels. Understanding the Janka hardness scale and the specific characteristics of different cedar types will provide a clearer picture.
What is the Janka Hardness Scale?
The Janka hardness scale measures the resistance of a wood species to denting and wear. It's determined by the force required to embed a steel ball halfway into the wood. Higher numbers indicate harder wood, while lower numbers signify softer wood. This scale is crucial for understanding a wood's suitability for different applications.
Where Does Cedar Fall on the Janka Hardness Scale?
Cedar species generally fall into the softwood category on the Janka hardness scale. However, there's significant variation depending on the specific type. For instance:
-
Incense Cedar: Typically registers around 350 lbf (pounds-force) on the Janka scale.
-
Western Red Cedar: Usually measures between 280-360 lbf on the Janka scale.
-
Eastern Red Cedar: This type tends to fall slightly above Western Red Cedar, but remains in the softer wood range.
This means that cedar is generally easier to work with than hardwoods like oak or maple, but it's also more susceptible to dents and scratches.
What are the Implications of Cedar's Softness?
Cedar's softness has both advantages and disadvantages:
Advantages:
-
Easy to Work With: Its softness makes it easy to carve, shape, and cut, making it a favorite for woodworking projects.
-
Lightweight: The lower density makes it ideal for applications where weight is a concern.
-
Pleasant Aroma: Many cedar species possess a distinct and pleasant aroma, making it popular for closets, chests, and other applications where fragrance is desirable.
Disadvantages:
-
Susceptibility to Damage: Its softness means it's more prone to dents, scratches, and other damage.
-
Less Durability: Compared to hardwoods, cedar generally has a shorter lifespan in high-traffic or high-wear areas.
-
Prone to Insect Damage: Although cedar's natural oils offer some insect resistance, it's not completely immune and can be susceptible to certain pests.
What Cedar Species are Considered "Harder"?
While cedar is generally considered a softwood, some species are comparatively harder than others. Within the cedar family, variations in density and grain structure contribute to hardness differences.
Is Cedar Suitable for Furniture?
The suitability of cedar for furniture depends on the specific application. It's better suited for less-stressed furniture pieces, such as chests of drawers or decorative items. For furniture that experiences significant wear and tear, a harder wood would be more appropriate.
Can Cedar be Used Outdoors?
Yes, many cedar species are naturally resistant to rot and decay, making them suitable for outdoor applications like fencing, siding, and decking. However, proper treatment and maintenance are still recommended to extend the lifespan and protect against insect damage.
What are the Best Uses for Cedar Wood?
Because of its unique properties, cedar finds its niche in many applications. These include:
- Architectural Elements: Siding, roofing shingles, decking.
- Interior Finishes: Paneling, trim, shelving.
- Furniture and Crafts: Small furniture pieces, carvings, boxes.
- Closets and Chests: Its aroma and insect-repellent properties make it suitable.
In conclusion, cedar is generally considered a softwood, but its hardness varies depending on the species. Understanding its properties is key to selecting the right cedar for your project and ensuring its longevity.
