The basic principles of building materials purchase

The quality of home improvement materials directly affects the effect of decoration, and it also brings certain influence to the future life. Therefore, the choice of materials for home furnishings is undeniably tens of millions, and the following four principles should be adhered to.

Environmental protection principle

The pollution of harmful gases, excessive radiation, etc. in residential buildings is generally caused by home improvement materials and has become a major aspect of residential pollution. Therefore, environmental factors must be taken into consideration when selecting materials. To choose building materials that have passed the national environmental certification, do not use building materials that the country has already banned or eliminated. Instead of decorating or decorating the building, do not use those materials that are harmful to the human body.

Practical principle

Decorative materials are not the higher grades the better, should be combined with the use of residential properties, with practical as a fundamental. Decoration materials should not only consider the decorative effect, but also should consider the improvement of the environmental conditions of the residence. For example, the selection of indoor ceilings and wall materials should be based on gypsum plasterboard. This material is not only low in price, but also resistant to fire and mildew. It can also absorb sound and heat and regulate the humidity of houses.

Balance principle

When determining the grade of decoration, you must consider your own economic conditions and do your best. In some areas that will not affect the quality and effectiveness of the overall renovation, some materials with slightly inferior grades can be selected to properly control costs. In some key areas, such as the ground, water supply and drainage, and the selection of electrical appliances, quality should be taken as the first priority. Considering its easy-to-deplete characteristics, it can be achieved in one step. It would rather spend more money and cannot repair it at a later date. In this way, the overall renovation costs are balanced, neither excessively increasing costs, but also achieving good results, but also economic benefits.

Innovation principle

As the saying goes, "Things are scarce and expensive." In the selection of residential home improvement materials, it is critical to highlight innovation. In the selection of residential home improvement materials, some new and breakthrough materials can be selected. This not only highlights the modern and advanced interior design, but also highlights individuality and is easy to create new ones.
