There are many consumers who choose ceramic tiles when they are decorating. They only pay attention to the price. In fact, sometimes people should pay attention to quality when buying things. Many people don’t know how much troubles inferior tiles will bring. So how do you buy the right tiles? Come and learn with us.
Appearance: Observe color and flatness. In general, the clearer the color of the tile, the better, look at the pinholes, the pinholes are easy to accumulate.
Sound: Listen to the density. The most important thing to choose a tile is to consider the quality problem. There are many standards for distinguishing the quality of the tile. It can be beaten. The sound is crisp and the ceramic tile has high density and good quality.
Size: On-site measurement. Measure with a ruler or tape measure, four sides and diagonal lines of the tile, and check the size.
Surface: Look at the quality from the traces. Check the surface quality of the tile, you can use a hard object to scrape the tile glaze to judge the surface of the tile.
Water absorption: Look at the water absorption rate of the tiles. In general, the low water absorption of tiles, the higher the inherent stability of the tiles, the more suitable for space with high moisture or moisture content (such as bathroom, kitchen), and no black spots and other problems. A common method for testing the water absorption rate of a tile is to pour the back of the tile, and the quality of the tile that penetrates slowly or even does not seep is good, and vice versa.
Aluminium Casement Windows
Aluminum alloy casement window is a common type of window with the following characteristics:
1. Structural characteristics
Frame
The frame is made of aluminum alloy profiles, which have the advantages of light weight, high strength and corrosion resistance. Its cross-sectional shape is diverse and can be selected according to different design requirements and stress conditions to ensure the stability of the window.
Opening method
The window sash is connected to the window frame through hinges and can be opened outward or inward. The outward opening type does not occupy indoor space and has a wide field of vision, but has higher requirements for the sealing and safety of the window; the inward opening type is convenient for cleaning the outside of the window, but it will occupy a certain amount of indoor space.
2. Performance characteristics
Good sealing
When the casement window is closed, the window sash fits tightly with the window frame, and with high-quality sealing strips, it can effectively prevent rain, dust and noise from entering the room. Its sealing performance is better than that of sliding windows, which can better maintain the indoor environmental quality.
Good ventilation
The opening angle can be adjusted according to needs to achieve good ventilation effect. Some casement windows can also be equipped with limit devices to control the opening angle to ensure safety while achieving ventilation.
Strong security
Hardware accessories such as hinges and locks can provide better security. If the outward-opening casement window adopts a multi-point lock system, it can effectively prevent the window sash from being pried open by external force; the inward-opening casement window is easy to operate indoors, and the safety can also be enhanced by adding guardrails.
3. Aesthetics and durability
Aesthetics
Aluminum alloy profiles can be subjected to a variety of surface treatments, such as anodizing, powder coating, fluorocarbon coating, etc., which can present different colors and textures, and can match various architectural styles to enhance the overall aesthetics of the building.
Durability
Aluminum alloy itself has good corrosion resistance and is not easy to rust. With proper maintenance, its service life is long. However, the quality of hardware accessories has a greater impact on the overall durability of the window. High-quality hardware accessories can ensure the long-term and stable use of the window.
