One, what types of new building materials are available?
New building materials are a type of new building materials. Different types of new building materials have different properties and functions, and the raw materials and manufacturing methods for producing new building materials are also different. In terms of their development, some types focus on appearance, with a wide variety of decorative and finishing materials; some types focus on functionality, such as insulation materials; and others are derived from multiple types through deep processing, such as new building panels.
Generally, there are dozens of types of new building materials. Among them, paper-faced gypsum board, glass fiber reinforced cement board (GRC), and asbestos-free silicon calcium board are currently the three most commonly used types of new building materials.
Two. What type of new building materials is the best?
Common types of new construction materials: These three types of boards differ not only in the raw materials used and the production processes, but also in their properties and functions.
1、Gypsum-based plasterboard primarily consists of gypsum and facing paper, suitable for interior wall panels and ceiling panels. Please refer to the following advantages and disadvantages:
Save Costs: The energy consumption required to produce equivalent units of paper-faced gypsum board is 78% less than that of cement. Furthermore, it offers a high investment return, simple processes, and ease of large-scale production.
Excellent fire resistance: Due to the non-combustible gypsum core and its ability to absorb a large amount of heat during combustion by releasing chemical compounds, which delays the rise in surrounding temperatures, paper-based gypsum boards exhibit excellent fire resistance.
Excellent soundproofing performance: Paper-faced gypsum board partitions have an innovative cavity structure that provides excellent soundproofing. Please refer to the following pros and cons:
Breathable and Eco-friendly: Due to the relatively high porosity and appropriate pore structure of gypsum boards, they exhibit excellent breathability.
Space-saving: Utilizing paper-faced gypsum board for walls, the wall thickness can be as thin as 74mm while maintaining the wall's soundproofing and fire resistance properties.
Prone to cracking: Cracks are likely to occur at the joints, reducing the soundproofing effect, and damaging its original function. Furthermore, the surface is prone to detachment after prolonged use.
Difficult to clean: It has poor stain resistance and is not easily cleaned.
2. The main raw materials for glass fiber reinforced cement boards are low-alkali cement and alkali-resistant glass fibers, suitable for both interior and exterior wall applications. Please refer to the following advantages and disadvantages:
Lightweight and High Strength: Fiber cement boards are produced by pressing sheet-like materials from a hydraulic press, resulting in high strength and resistance to deformation and warping. They are lightweight and ideal for ceiling applications on roofs.
Easy Construction: Fiber cement boards are characterized by dry installation, which allows for fast construction and installation speeds, and also simplifies the production of deep-processed products.
Economical and Aesthetic: Fiber cement boards are lightweight and, when combined with timber framing, can reduce costs for both factories and renovations. This results in a smooth surface and uniform architectural color.
Fire resistance and insulation: Fiber cement boards are classified as Class A (non-combustible). In the event of a fire, the boards will not emit toxic fumes, and their low electrical conductivity makes them an ideal insulation material.
Long Lifespan: Fiber cement boards are resistant to deformation even in semi-outdoor and high-humidity environments, and they possess resistance to acids and corrosion. Their strength increases over time, resulting in a very long service life.
Unsuitable: If the asbestos cement board is made of asbestos fibers, this type of board is an environmentally unfriendly material, containing carcinogenic substances, and is generally not used in hospitals, food processing plants, and other buildings. Even if it does not contain asbestos fibers, it is relatively environmentally friendly, but it has drawbacks such as high price and low strength.
Prone to deformation: Different densities of boards have different applications. For example, low-density boards can be used for partition walls in low-grade buildings; medium-density boards are commonly used for partition walls and ceilings in mid-range buildings; and high-density boards are primarily used for steel structure outfitting in buildings, but are prone to deformation.
3. The main raw materials for silicone-calcium boards are silicone-calcium materials. Besides being used for interior and exterior wall panels, they can also be used for renovation and furniture manufacturing. Please refer to the following advantages and disadvantages:
Excellent fire resistance: Calcium silicate boards are A-rated non-combustible materials. In the event of a fire, the boards will not burn and will not produce toxic fumes.
- Excellent water resistance: Silicon calcium boards offer excellent water resistance, maintaining their performance in high-humidity areas such as bathrooms and toilets, without swelling or deformation.
High Strength: Calcium silicate board offers high strength, resulting in a solid and durable wall that is resistant to damage and cracking.
- Excellent insulation and soundproofing properties: Calcium silicate boards offer excellent thermal insulation and soundproofing performance.
Long Service Life: The silicon calcium board exhibits excellent performance, with stability, resistance to acids and alkalis, and is not susceptible to corrosion or damage from moisture or pests, ensuring a long service life.
Difficult to replace: After installing calcium silicate board, changing the layout of the partitions becomes difficult.
Higher cost: Requires the use of metal-based studs during installation, resulting in a complex and expensive project.
It can be said that which type of new building material panel is the best? Regarding this issue, everyone can consider the advantages and disadvantages of each type based on the above information, and make selections based on their own needs and conditions.
