Among high-end flooring materials, black walnut flooring has won the favor of consumers and designers with its unique texture, noble color and excellent stability. It is not only a flooring material, but also a symbol of taste. However, the quality of black walnut flooring on the market varies greatly, and the price difference is large. How can you choose high-quality black walnut flooring? This article will analyze it in detail from multiple professional perspectives.
1. Basic characteristics of black walnut flooring
Before choosing, it is very necessary to understand the basic knowledge of black walnut. Black walnut , scientific name Juglans nigra, is mainly produced in North America and belongs to a precious hardwood species. Its wood color is deep, ranging from chocolate to purple brown, with natural wavy or spiral texture, which is very ornamental.
Advantages include:
Natural texture and rich texture, very suitable for high-end residential and commercial spaces.
Moderate hardness, comfortable foot feel, not too stiff or soft.
Strong durability, durable, strong resistance to deformation.
Good stability, not easy to crack, shrink or expand.
After understanding these characteristics, we can judge and choose high-quality products more specifically.
2. Grades and types of black walnut floors
The black walnut floors sold on the market are not exactly the same. If you want to buy truly high-quality products, you must start with the grade and type of board.
2.1 Log grade
According to the US NHLA standard (National Hardwood Graders Association), black walnut is usually divided into the following grades:
FAS (First and Seconds): The highest grade, complete material, few knots, and uniform color
Select (Selected): Slightly inferior to FAS, allowing a small amount of natural defects
No.1 Common (First Common): Large color difference, more knots, and lower price
Among floor materials, FAS and Select grades are more commonly used for high-end solid wood floors. When purchasing, you can ask the merchant to provide NHLA grade certification.
2.2 Solid wood vs. solid wood composite
There are two main forms of black walnut floors:
Solid wood flooring: Made from a whole piece of black walnut, it has a strong natural feel, but the price is high and the environmental requirements are high (humidity control).
Solid wood composite flooring: The surface is black walnut, and the base is multi-layer solid wood composite board. It has a stable structure and high cost performance, which is suitable for most families.
If you have a sufficient budget and pursue the feeling of original wood, you can choose solid wood; if you pay more attention to the balance between stability and price, solid wood composite flooring is a more rational choice.
3. Processing technology and surface treatment technology
Even for black walnut of the same grade, its processing technology also determines the use experience and life.
3.1 Surface treatment method
Open coating (Open Pore): retain the natural pores of the wood, the touch is natural, but it is easier to accumulate dust.
Closed coating (Closed Pore): The surface is smooth and delicate, easy to clean, but it loses the natural wood feel.
Wire drawing process: mechanical wire drawing is used to strengthen the texture level, which is suitable for retro style decoration.
UV paint/matte paint treatment: enhances wear resistance and anti-slip effect, and also helps to resist UV aging.
3.2 Precision of joints and mortise and tenon
High-quality floors are tightly spliced, without obvious gaps, and the mortise and tenon are smooth without burrs, giving a strong overall feel after installation.
4. Environmental performance
As a household material that is in long-term contact, the environmental performance of black walnut flooring directly affects the health of the family.
4.1 Formaldehyde emission standard
Solid wood itself is non-toxic, but glue and paint may contain formaldehyde.
When purchasing, check whether the environmental protection level of the product reaches E0 or F★★★★ (Japanese standard).
4.2 Certification marks
High-quality floors often have multiple certifications, such as:
FSC certification: sustainable forest certification
CARB certification: California Air Resources Board certification
FloorScore certification: North American air quality environmental certification
These certification marks are important bases for judging environmental protection and health.
Black walnut flooring is a high-end building material that combines beauty and practicality. When purchasing, you should pay attention to the natural properties of the wood itself, as well as the product process, structural design and environmental performance.
