What is the function of suspended ceiling?
1. Improve the indoor environment and meet the functional requirements.
The design of suspended ceiling should not only consider the requirements of indoor decoration effect and artistic style, but also consider the requirements of the building's use function on technical performance such as lighting, ventilation, heat preservation, heat insulation, sound absorption or reflection, sound insulation and fire prevention, which directly affect the indoor environment and use. For example, the ceiling of a theater should consider many problems of optical and acoustic design comprehensively.
2. Decorate indoor space
Ceiling is an important part of interior decoration. Besides walls and floors, it is another big surface around the indoor space. It plays an important role in rendering the room environment and setting off the atmosphere from the aspects of space, light, shadow and materials.
Types of ceiling materials
There are many ceiling materials on the market at present. There are two main types of traditional materials: PVC ceiling and metal ceiling. Can these two materials meet people's needs? The popularization of suspended ceiling in previous years has promoted the constant change and innovation of suspended ceiling materials. Now it has developed from gypsum board to pvc board, ps board, mineral wool board, aluminum ceiling, colored glass and so on. Both traditional materials and new-generation composite materials have occupied suitable consumer groups in the market.
Gypsum board is light in weight and low in price.
This is one of the commonly used ceiling materials in the past, with light weight and low price. Due to different sizes and specifications, it ranges from ten yuan to dozens of yuan per square meter. Early gypsum board had poor moisture-proof and fire-proof performance, but now there are fire-proof and moisture-proof products. However, it is necessary to install keel to use gypsum board as ceiling. Some ordinary gypsum will be pulverized and sunken after being used for a long time, so it is difficult to find traces in the current home improvement material market.
PVC board is economical and practical.
PVC board is cheap and practical, and it is the first choice for ceiling materials in home improvement. Prices range from a few yuan per square meter to more than 20 yuan. Made of PVC, light weight, waterproof, moisture-proof and moth-proof. Due to the addition of flame retardant materials in the production process, it is safe to use. There are many colors and patterns of PVC board, most of which are plain colors, and some are imitation patterns and marbles. Its cross section is a honeycomb-like net structure with grooves and tenons on both sides. When choosing this kind of material, we should pay attention to the surface without cracks and scratches, the tongue-and-groove is complete and straight, the mutual occlusion is smooth, and there is no ups and downs locally. The plate is flexible and elastic, and the sound of knocking on the surface by hand is crisp, and it will not sink and deform under certain pressure. Its disadvantages are poor high temperature resistance and easy deformation in thermal environment for a long time.
PS board has a good decorative effect.
This is a new imported material with strong color, great elasticity, light weight and good light transmittance, and it is an ideal ceiling material. PS board has a variety of patterns, such as bark patterns, running water patterns, beads and so on, which will not fade and age. Because of its good light transmission, lighting lamps can be installed in the ceiling to form uniform astigmatism and temperature radiation effects, which is very decorative. The price of PS board is relatively high, about RMB 0/00 per square meter/kloc ~200 yuan.
Mineral wool board has good sound absorption effect.
Made of mineral fiber, the biggest feature is good sound absorption effect. Its surface is knurled and embossed, and the patterns are starry sky, cross flower, central flower and walnut pattern. Mineral wool board can sound insulation, heat insulation and fire prevention. Slightly high-grade products do not contain asbestos, which is harmless to human body and has anti-settling effect. The price is also moderate, ranging from 20 yuan to 50 yuan per square meter.
Ceiling design should not only consider the requirements of interior decoration effect and artistic style, but also directly affect the indoor environment and use. These are the functions and types of ceilings that Bian Xiao introduced to you today. Here it is.
