The main difference between rubberwood and solid wood is that rubberwood is one specific type of solid hardwood, while solid wood is a broad category that includes many different wood species. Rubberwood is commonly used for furniture, cabinets, flooring, and interior applications, while some solid wood species are suitable for both interior and exterior applications.
So, it would not be accurate to say that solid wood is always stronger than rubberwood. Solid wood includes hundreds of species with different levels of hardness, strength, durability, and moisture resistance. Some are stronger than rubberwood, while others are softer.
What Is Rubberwood?
Rubberwood is a light-colored, medium-density hardwood obtained from the rubber tree, Hevea brasiliensis. It is also commonly known as Parawood.
Rubberwood is a true hardwood and is widely used for furniture, cabinets, flooring, interior millwork, and other woodworking projects.
The rubber tree is native to the Amazon region of South America, but it is now widely cultivated in tropical regions, particularly in Southeast Asia. The tree is primarily grown for latex production, which is used to make natural rubber.
When rubber trees become less productive for latex, they can be harvested and used for timber. This gives rubberwood an important secondary use rather than leaving the trees as agricultural waste.
What Is Solid Wood?
Solid wood refers to lumber or wood products made from natural wood rather than engineered wood composites.
The term does not describe a single species. Solid wood can come from many different trees and includes both hardwoods and softwoods.
Examples of solid wood species include:
- Oak
- Maple
- Walnut
- Cherry
- Mahogany
- Teak
- Pine
- Cedar
- Douglas fir
Because different species have different properties, there is no single hardness, strength, or durability rating for solid wood.

Rubberwood Characteristics
Here are some important properties of rubberwood:
| Property | Rubberwood |
|---|---|
| Scientific Name | Hevea brasiliensis |
| Common Names | Rubberwood, Parawood |
| Type | Hardwood |
| Average Dried Weight | About 37 lb/ft³ (595 kg/m³) |
| Janka Hardness | About 960 lbf (4,280 N) |
| Elastic Modulus | About 1.31 million lbf/in² (9.07 GPa) |
| Primary Color | Creamy white to light brown |
| Typical Uses | Furniture, cabinets, flooring, millwork, crafts |
The Janka hardness test measures a wood’s resistance to indentation. Rubberwood’s rating of about 960 lbf places it in the moderate range compared with the very wide range of hardness found across different wood species.
Uses of Rubberwood
Rubberwood is commonly used for:
- Furniture
- Cabinets
- Tables and chairs
- Flooring
- Interior millwork
- Moldings and trim
- Cutting boards
- Kitchen accessories
- Crafts
- DIY projects
Its light color and relatively uniform appearance make it particularly suitable for furniture and interior applications.
Uses of Solid Wood
Solid wood has a much wider range of applications because it includes many different species.
Depending on the species, solid wood can be used for:
- Furniture
- Cabinets
- Flooring
- Construction
- Doors
- Windows
- Siding
- Decking
- Boatbuilding
- Tools and handles
- Musical instruments
- Interior millwork
- Outdoor structures
For example, teak and some cedar species are commonly selected for outdoor applications because of their natural durability, while softer species may be better suited to interior applications.
Workability
Rubberwood
Rubberwood is generally easy to machine and work with because of its moderate density and relatively uniform grain.
However, improperly dried rubberwood can have moisture-related movement and may warp or distort. Properly dried and conditioned material is therefore important for furniture and other woodworking projects.
Rubberwood can be machined, glued, stained, and finished successfully when properly prepared.
Solid Wood
The workability of solid wood depends entirely on the species.
Some relatively soft species, such as pine, basswood, aspen, and cedar, are generally easy to work with.
Denser hardwoods such as teak, ebony, lignum vitae, and some species of walnut can require more effort and may be harder on cutting tools.
Therefore, it is not accurate to describe all solid wood as either easy or difficult to work with.
Hardness
Rubberwood has a Janka hardness of approximately 960 lbf (4,280 N).
The hardness of solid wood varies substantially because solid wood is a category rather than a single species.
For example:
| Wood Species | Approx. Janka Hardness |
|---|---|
| Balsa | 67 lbf |
| Northern white cedar | 320 lbf |
| Aspen | 350 lbf |
| White fir | 480 lbf |
| Honduran mahogany | 900 lbf |
| Rubberwood | 960 lbf |
| Black walnut | 1,010 lbf |
| Acacia blackwood | 1,160 lbf |
| Blue ash | 1,290 lbf |
| Sapele | 1,410 lbf |
| Hard maple | 1,450 lbf |
| Honey locust | 1,580 lbf |
| Wenge | 1,930 lbf |
| Ipe | 3,510 lbf |
| Lignum vitae | 4,390 lbf |
This comparison shows why it is difficult to say that rubberwood is simply weaker or stronger than “solid wood.” Rubberwood itself is solid wood.
Is Rubberwood Rot and Insect Resistant?
Rubberwood has relatively low natural resistance to decay and insects.
It is generally intended for interior applications unless it has been appropriately treated and protected for a specific exterior application.
Prolonged exposure to moisture can increase the risk of fungal decay and other deterioration.
By comparison, some solid wood species have naturally high decay resistance. Teak, for example, is well known for its durability in outdoor environments, while other solid wood species have much lower natural resistance.
This is why the species and intended application are more important than simply choosing between “rubberwood” and “solid wood.”
Is Rubberwood Real Wood?
Yes. Rubberwood is real solid wood.
It comes directly from the rubber tree, Hevea brasiliensis, and is a true hardwood.
Rubber trees are primarily cultivated for latex production. Once trees become less productive for latex, they can be harvested for timber and used to manufacture furniture and other wood products.
This gives rubberwood a useful secondary role in the rubber industry.
Is Rubberwood Sustainable?
Rubberwood can be considered a useful example of wood obtained from trees that were originally cultivated for another purpose.
Rubber plantations are primarily established for latex production. When older trees become less productive, using their wood for furniture and other products can extend the value of the tree.
However, the sustainability of rubberwood still depends on factors such as plantation management, transportation, processing, and responsible sourcing.
Therefore, rubberwood should not automatically be considered sustainable simply because it comes from old rubber trees.
Is Rubberwood Good for Flooring?
Rubberwood can be used for flooring, particularly in interior applications.
Its moderate hardness provides reasonable resistance to everyday dents and wear, while its light color can create a clean, bright appearance.
However, rubberwood has relatively low natural resistance to decay and moisture. It should therefore be properly finished and protected from prolonged exposure to water.
For high-moisture or exterior flooring, a naturally durable wood species or a product specifically designed for those conditions may be a better choice.
Is Rubberwood Waterproof?
No, rubberwood is not waterproof.
Like other natural wood species, rubberwood can absorb and release moisture.
A suitable finish can help reduce moisture penetration, but it does not make the wood completely waterproof.
Rubberwood is therefore better suited to interior applications where moisture can be controlled than to constantly wet outdoor environments.
Rubberwood vs Solid Wood for Furniture
The Rubberwood is often a good choice for furniture because it is:
- Relatively affordable
- Light-colored
- Easy to machine
- Easy to finish
- Available in consistent sizes
- Suitable for many interior applications
However, if you need furniture for an outdoor environment, the choice of species becomes much more important.
Naturally durable solid woods such as teak or certain cedar species can perform better outdoors than untreated rubberwood.
Rubberwood vs Solid Wood: Which Is Stronger?
It depends on the specific solid wood species.
Rubberwood has a Janka hardness of approximately 960 lbf. Some solid woods, such as balsa and cedar, are much softer, while others, such as hard maple, ipe, and lignum vitae, are significantly harder.
Also, hardness is not the same thing as overall strength. Janka hardness measures resistance to indentation; it does not directly measure bending strength, stiffness, or structural capacity.
Therefore, you should compare the specific species and the property that matters for your project rather than simply comparing rubberwood with “solid wood.”
Rubberwood vs Solid Wood: Which Is Better?
There is no universal winner.
Rubberwood is a good option when you need an affordable, light-colored hardwood for furniture, cabinets, flooring, and other interior applications.
Solid wood is the better choice when you need a specific combination of strength, hardness, durability, appearance, or outdoor performance because you can select a species based on those requirements.
For example:
- Furniture: Rubberwood can be an excellent option.
- Interior cabinets: Rubberwood is suitable.
- Indoor flooring: Rubberwood can work well with an appropriate finish.
- Outdoor furniture: A naturally durable solid wood such as teak may be better.
- Outdoor decking: Choose a species specifically suited to exterior exposure.
- Heavy-duty applications: Select the solid wood species based on its actual strength and hardness requirements.
Final Verdict
Rubberwood is not separate from solid wood—it is a specific solid hardwood species. The real comparison is between rubberwood and other solid wood species.
Rubberwood is a relatively affordable, light-colored hardwood that is commonly used for furniture, cabinets, flooring, and interior products. It has a Janka hardness of about 960 lbf and is generally easy to work with.
Its main limitation is its low natural resistance to decay and moisture, which makes untreated rubberwood less suitable for prolonged outdoor exposure.
Solid wood, on the other hand, includes a huge range of species. Some are softer than rubberwood, while others are significantly harder and more durable.
If you are choosing wood for an indoor furniture or cabinetry project, rubberwood can be a practical and economical option. If you need outdoor durability or specific structural properties, compare rubberwood with the particular solid wood species you are considering.
