Wooden composite panels are sheets composed of several layers. One central or nuclear layer, and at least two or more upper covering layers. The top layer is glued to the central layer and turned into a multi layer material. When we talk about the wooden nature of these panels, we are focusing on the top layer of the panel. This wood layer is not made of natural wood indeed, which is why it has become a popular type of composite panels among consumers.
Materials used in wooden panel composite
Materials used in wooden composite panels, like other aluminum composite panels (ACPs), include a wide range to create a variety of these panels. The central layer is made of polyurethane foams such as polyurethane sponges, rock wool, egg shoulder foams, rebound foam, XPS foam and flex panel. In some cases, the foam spray is selected as the center layer. In this method, the insulating material is placed on the plate as a solid foam after spraying with air as soon as it is sprayed. Finally, the top layer, which is the outer or covering layer, is placed on the foam.
The coating layers are also placed on the top layers based on the purpose of construction and technology consist of variety of colors, matte or glossy coatings, or purpose-coated coatings, such as fire retardant, anti-dust, antibacterial and anti-moisture.
In general, the thickness and variety of materials used in the central layer, as well as the coatings or facing of these panels, make a wide variety of them. As a result, there are many criteria for classification. Of course, the technology of construction and variety of materials is such that each manufacturer can use a new method in the construction and design of the panel and choose its own name for its product.
There is virtually no codified classification of these types of composites, but in terms of the raw material of the composite, these panels can be divided into four types. In general, composite products are made of wood products and can include the following raw materials:
- Chopped wood boards, which are made of firmly pressed wood.
- MDF, which is a fiberboard with medium density or density.
- Engineered wood, which is used for interior or exterior design and gives the output a traditional appearance, can also be resistant to factors such as moisture and heat.
- Multi-layer board, which is made by pressing and heating thin layers of wood.
Division in terms of appearance
1) Rough sawdust: This type of appearance has been a popular type for many years, but it can bend or even break if it`s not installed properly or firmly attached. High quality panels of this type are made of premium wood and adhesive and are much thinner than other cheap ones. These woods can have grooves that are either spaced apart or flat. These panels are usually installed on the exterior so that the grooves placed vertically. This installation method is to guide the rainwater down.
2) Smooth pattern: This type is usually used for a series of narrow boards that are placed side by side to cover a surface.
3) Cement and Fiber type: This panel is a composite of cement and fiber and is available in a variety of raw or polished types.
4) Multi-layered pressed board: The appearance of these panels is prominent and its texture is clear. These panels should be covered with several layers of veneer, otherwise they will melt and swell like sponges.
The third type mentioned above is also known as the “fiber cement board “. Fiber cement is a cementitious sheet that contains fibers in its composition and therefore is highly resistant. These fiber cement fixtures themselves are divided into various types, and their applications, like other products, include a range of facades, flooring, partitions, false ceilings, partitioning walls, and even more. Fiber cement can be prepared raw or processed, and the raw type is compatible with a variety of processed layouts. One of the great advantages of using wooden composite panels in construction is that there is no need for mortar, because working with these composite panels is done with a dry system. Their resemblance to thermo wood or so-called heated wood has also made them common in use for facades of buildings (especially villa buildings). The attributes of wooden design cement boards make them a unique option for application in temperate places and humid environments because the similarity of cement board to natural wood is perfectly compatible with the climate of the region, and in addition, the cement used in it prevents mold and insect attack. The cement board itself is installed by two methods of shuttering (or siding), and bed.
