Is multi-layer board better or three-layer board better? Which is better, solid wood multi-layer board or three-layer board?

The whole piece looks good like a floor.

Multi-layer solid wood composite flooring is based on multi-layer boards arranged vertically and horizontally, and high-quality precious wood is selected as the panel. After being coated with resin glue, it is made under high temperature and high pressure in a hot press, making it easier to process.

The surface of multi-layer and three-layer solid wood flooring plays a very important role. The surface of multi-layer solid wood flooring is required to be 0.6-2.0mm thick, while many domestic floors are only 0.6-1.2mm thick. The surface of three-layer solid wood flooring is generally 3mm, 4mm, or even 6mm. After a few years of use, it can be polished and refurbished again without exposing the core board.

Due to many factors such as production technology and material utilization rate, the price of multi-layer solid wood is obviously lower than that of three-layer solid wood.

The choice of floor covering material is crucial during renovations. Currently, the two main types are tile and flooring. With growing environmental awareness in recent years, flooring has become increasingly popular. Engineered wood flooring, as one type, is also gaining popularity. So, which engineered wood flooring is best? What's the difference between three-layer composite and multi-layer? Let's take a look.

Which solid wood composite floor is better?

1. Look at the product specifications. The service life of solid wood composite flooring is mainly determined by its surface layer. The thicker the surface layer, the more wear-resistant the floor.

2. Look at the precision. High processing precision is the advantage of solid wood composite flooring. When purchasing, be sure to observe whether the joints between the two floors are tight and whether there is any obvious difference in height.

3. Look at the surface paint film. Generally, high-grade solid wood composite floors use high-grade UV matte paint with good wear resistance.

4. Check the adhesive. The adhesive of solid wood composite flooring is generally made of urea-formaldehyde resin. However, high-end environmentally friendly solid wood composite flooring must use adhesive with low formaldehyde content. When purchasing, be sure to read the environmental index test report;

5. Regarding after-sales service, consumers should ask clearly about future installation and after-sales issues, and adhere to the principle of "whoever sells the floor is responsible for construction and after-sales service."

The difference between three-layer composite board and multi-layer board

There are few choices of solid wood composite flooring on the market now. The surface material is used as the reference standard for consumers. The main choice is based on the floor structure. It is mainly divided into three-layer solid wood composite flooring and multi-layer solid wood composite flooring.

The manufacturing process, application scope and price of the two are also different. Let's compare them first.

1. Three-layer solid wood composite flooring

Production process: Flooring made of solid wood panels or veneers as the top panel, solid wood strips as the core board, and veneer as the bottom board.

Advantages: effectively reduce the deformation of the floor, increase stability, comfortable feeling for feet, and effectively save wood.

Disadvantages: If the gluing quality is poor, degumming will occur, and the wear resistance is not as good as multi-layer composite solid wood flooring

Applicable scope: living room, dining room, bedroom, etc.

Reference price: about 400 to 660 per square meter

2. Multi-layer solid wood composite flooring

Production process: Multi-layer plywood is used as the base material, the surface is hardwood veneer or sliced ​​veneer, and it is made by hot pressing with glue.

Advantages: good stability, especially in geothermal environment, strong heat resistance, not easy to deform.

Disadvantages: If the gluing quality is poor, degumming may occur.

Scope of application: living room, dining room, bedroom, etc., also suitable for geothermal floor

Reference price: about 450-690/square meter.

Eco-board : Commonly known as paint-free board and melamine board . Like traditional paint-free and melamine boards, eco-board is finished with a melamine finish. Eco-board differs in that it uses environmentally friendly adhesives and is heat-pressed onto less-used blockboard or multi-layer boards. This decorative panel offers improved environmental performance. However, the performance of eco-board depends primarily on the core material, the quality of which significantly impacts its performance.

Multi-layer board: also called plywood , is a three-layer or multi-layer board made by peeling logs or planing wood into thin veneers, which are glued together with adhesives and high temperature pressing.

Different raw materials used

The raw materials used for ecological boards are square wood or round wooden sticks of the same size, while the raw materials used for multi-layer boards are just a simple single board. Ecological wood has the characteristics of being recyclable and has better nail holding power.

Different production processes

Eco-board is produced by splicing or tooth-jointing wood planks. Multi-layer boards are made by laying out layers of veneer boards horizontally and vertically, then splicing, seaming, or beveling them together. Eco-boards offer authenticity, resembling the feel and natural texture of real wood, with vibrant colors, making them both beautiful and practical.

Adhesives

Eco-boards use less glue, while multi-layer boards use a relatively larger amount of glue. The two are equally environmentally friendly, neither uses harmful materials, and eliminates decoration pollution, so they can be used with confidence.

Physical properties and uses Ecological boards have the properties of anti- ultraviolet , antibacterial, sound insulation, insulation and antistatic, so ecological boards are more suitable for use in wardrobes.

Multi-layer solid wood board

It has the characteristics of being not easy to deform, having good structural stability and not easy to deform, so multi-layer boards are more suitable for use in shoe cabinets.

Price

The production cost of multi-layer boards is relatively high, so the price is mostly higher than that of ecological boards. In comparison, the cost performance of ecological boards is higher.

Ecological board

Ecological board refers to the melamine veneer panel with the base material of multi-layer solid wood (plywood) or blockboard (such as Malacca, fir, paulownia, poplar, etc.).

Advantages: Eco-board is particularly fire- and moisture-resistant, making it commonly used in cabinets, bathroom vanities, and other products. Furthermore, it resists discoloration and peeling, allowing it to be processed into a variety of stylish, high-quality veneers. Installation is efficient and quick, allowing for easy nailing, planing, and sawing, eliminating the need for paint and odor. Once installed, it can be used immediately, saving time, effort, and money.

Disadvantages: Eco-board requires certain cutting and edge-banding processes, and improper processing can easily lead to disfigurement. For this reason, eco-board cannot be engraved, and relief-style sculptures cannot be created. Eco-board products on the market vary in quality and price, making it difficult for consumers to choose.

Multilayer board

1. Made of three or more layers of veneer or thin wood panels glued together and hot pressed.

2. Plywood is generally divided into six specifications: 3cm, 5cm, 9cm, 12cm, 15cm and 18cm (1cm is 1mm). It is the most commonly used material for handmade furniture.

3. The advantages of multi-layer boards are small deformation, high strength and good internal quality.

Advantages: Multi-layer solid wood flooring is an ideal material for furniture. Because it's typically made of multiple layers of plywood, it's stronger and more stable than other wood panels. It's also aesthetically pleasing and comfortable to the touch. Another major advantage is its ability to effectively regulate humidity and temperature in a room. Furthermore, multi-layer solid wood flooring uses environmentally friendly glue, making it a particularly environmentally friendly option.

Disadvantages: There are two main disadvantages to multi-layer solid wood boards. One is that they require very high craftsmanship, such as sanding and cold pressing. If the processing does not meet the standards, the desired effect cannot be achieved. Therefore, multi-layer solid wood boards produced by manufacturers with low craftsmanship are generally of low quality. Despite this, they are still put on the market in large quantities, which requires consumers to carefully select them when purchasing. Another is that when making multi-layer solid wood boards, if unscrupulous manufacturers use low-quality glue, it may cause the boards to separate and deform, resulting in a shortened service life.

Five-layer board.

Stage flooring must be structurally sound. Stage flooring is divided into fixed and movable surfaces. Fixed wood floors are used on the concrete floor, while movable wood floors are used on the steel structures of turntables and lifts. The floor height can be adjusted to ensure a consistent surface height across the entire finished floor. The movable wood flooring utilizes a five-layer structure, with a top layer of 25mm x 85mm x 1200mm double-jointed finger-jointed flooring, a second layer of 20mm thick multi-layer plywood, and a third layer of 20mm thick waterproof multi-layer plywood. The bottom layer consists of 50mm thick by 55mm wide pinewood keels with a center spacing of 400 mm. 10mm x 50mm x 60mm rubber pads are placed between the keel and the steel frame.
