What are system doors and windows and non-system windows? The difference between system doors and windows and non-system windows

In recent years, with the continuous development of the construction industry, the performance and quality requirements of doors and windows have become increasingly higher. Among the many door and window products, "system doors and windows" and "non-system windows" have become two categories that have attracted much attention. However, many people are still unclear about the definitions, characteristics and differences between the two. This article will analyze system doors and windows and non-system windows in detail from many aspects such as definition, structure, performance, application, etc., to help everyone better understand and choose the product that suits them.

1. Basic concepts

1. System doors and windows

System doors and windows refer to a type of door and window products that are designed and manufactured systematically, taking into account various factors such as building structure, climate characteristics, usage functions, etc., to ensure that the performance indicators of doors and windows meet expected requirements. System doors and windows are usually provided by professional door and window system companies. They have formed a complete technical system through years of R&D and testing.

2. Non-system window

Non-system windows, as the name suggests, are those door and window products that have not been systematically designed and tested. They are usually designed and produced by door and window manufacturers themselves according to market demand. Due to a lack of systematic R&D and testing, the quality and performance of non-system windows varies.

2. Structure and composition

1. Structure of system doors and windows

The structure of system doors and windows is relatively complex and consists of the following main parts:

• Profiles: The profiles of system doors and windows are generally made of high-strength aluminum alloy, plastic steel and other materials, and have undergone strict mechanical performance testing to ensure strength and durability.

• Glass: Use high-grade insulating glass, laminated glass, etc., with good sound insulation and heat insulation properties.

• Hardware: The hardware of system doors and windows is usually provided by professional manufacturers and has been rigorously tested to ensure smooth opening and closing and high durability.

• Sealing strips: Use high-quality sealing strips to ensure that doors and windows are air- and water-tight.

• Accessories: including locks, hinges, pulleys, etc., all professionally designed to ensure overall performance.

2. Structure of non-system windows

The structure of the non-system window is relatively simple and mainly consists of the following parts:

• Profile: It can be made of aluminum alloy, plastic steel and other materials, but it is usually not strictly tested.

• Glass: Ordinary glass, insulated glass, etc. may be used, but the quality and performance vary.

• Hardware: The quality and performance of hardware vary, and there may be problems such as sluggish opening and closing and poor durability.

• Sealing strips: Sealing strips vary in quality and may affect the air and water tightness of doors and windows.

• Accessories: vary in quality and may affect overall performance.

3. Performance comparison

1. Performance of system doors and windows

• Sound insulation performance: The system doors and windows use high-quality insulating glass and sealing strips, which can effectively isolate external noise and provide a quiet indoor environment.

• Thermal insulation performance: The profiles and glass of system doors and windows have good thermal insulation properties, which can effectively reduce energy consumption and maintain indoor temperature.

• Air tightness and water tightness: The sealing strips and structural design of system doors and windows ensure good air tightness and water tightness to prevent wind and rain from penetrating.

• Safety performance: The profiles and hardware of system doors and windows have been rigorously tested and have good wind pressure resistance and anti-theft performance.

• Durability: System doors and windows are made of high-quality materials and workmanship, providing a long service life and reducing subsequent maintenance costs.

2. Performance of non-system windows

• Sound insulation performance: Due to the varying quality of glass and sealing strips, the sound insulation performance of non-system windows varies and may not effectively block outside noise.

• Thermal insulation performance: The profiles and glass of non-system windows are of varying quality, and the thermal insulation performance may be poor, affecting indoor temperature regulation.

• Air tightness and water tightness: The quality of sealing strips varies, which may result in poor air tightness and water tightness of non-system windows, and there is a risk of wind and rain penetration.

• Safety performance: Due to the varying quality of profiles and hardware, non-system windows may have poor wind pressure resistance and anti-theft performance, posing safety risks.

• Durability: Non-system windows vary in quality of materials and workmanship, have a shorter lifespan, and may require frequent maintenance and replacement.

4. Application scenarios

1. Application of system doors and windows

System doors and windows are widely used in the following scenarios due to their superior performance:

• High-end residences: The system doors and windows have excellent sound insulation and heat insulation properties and are suitable for the needs of high-end residences.

• Commercial buildings: The system doors and windows have good air and water tightness and are suitable for the high standards of commercial buildings.

• Public buildings: The system doors and windows have high safety performance and are suitable for the safety needs of public buildings.

• High-rise buildings: The system doors and windows have strong wind pressure resistance and are suitable for the use environment of high-rise buildings.

2. Application of non-system windows

Due to different performance, non-system windows are mainly used in the following scenarios:

• Ordinary residences: Non-system windows are cheaper and suitable for the needs of ordinary residences.

• Low-rise buildings: Non-system windows have average wind pressure resistance and are suitable for use in low-rise buildings.

• Temporary buildings: Non-system windows are low-cost and suitable for the use needs of temporary buildings.

5. Selection suggestions

1. Suggestions for choosing system doors and windows

• Pay attention to brand and reputation: Choose system doors and windows from well-known brands to ensure product quality and after-sales service.

• Pay attention to performance indicators: Choose system doors and windows that meet your own needs, such as sound insulation, heat insulation, air tightness and other indicators.

• Comprehensive consideration of costs: Although system doors and windows are more expensive, their superior performance and long service life can reduce subsequent maintenance costs.

2. Suggestions for choosing non-system windows

• Pay attention to profile quality: Choose profiles with better quality to ensure the basic performance of doors and windows.

• Choose regular manufacturers: Choose qualified regular manufacturers to reduce quality risks.

• Control the budget: According to your own budget, choose a non-system window with a relatively balanced performance and price.

System doors and windows and non-system windows each have their own advantages and disadvantages. When choosing, you need to consider comprehensively based on your own needs and budget. Although system doors and windows are more expensive, their superior performance and long service life give them obvious advantages in high-end residences, commercial buildings and other scenarios. Non-system windows are suitable for ordinary residences, low-rise buildings and other scenarios because of their lower cost.

Regardless of whether you choose system doors and windows or non-system windows, you should pay attention to the quality and performance of the product, and choose regular manufacturers and well-known brands to ensure the safety and durability of doors and windows. Through scientific and reasonable choices, we can provide ourselves and our families with a comfortable and safe living environment.
