PART.01 / Sound insulation

Sound insulation refers to the ability to attenuate the sound transmitted from a sound source to the listener. The room house is close to the road, the traffic is noisy, and the elderly and children are always resting badly? In order to ensure the quality of rest for the family, the choice of doors and windows should focus on the sound insulation performance of doors and windows.

PART.02 / Heat insulation performance

Many people know a common sense that protective building materials such as doors and windows have a certain thermal conductivity coefficient, and the lower the thermal conductivity coefficient, the better the thermal insulation of doors and windows; Conversely, the worse the thermal insulation performance of doors and windows.

The thermal insulation performance of doors and windows affects the comfort of the room environment, the thermal insulation performance is too poor, the floor heating is slow in winter, and the air conditioning is slow in summer, which is also a very distressing thing, so in order to ensure the comfort of the family, the choice of doors and windows should focus on the thermal insulation performance of doors and windows.

PART.03 / Wind and Compression Resistance

Wind pressure resistance refers to the ability of closed exterior (door) windows and windows to avoid damage and dysfunction under wind pressure. Wind pressure resistance is divided into 9 grades, and the higher the grade, the stronger the wind pressure resistance.

The wind pressure performance rating is not the same as the typhoon rating. Wind pressure resistance level 12 means that the window can withstand wind pressure above 0pa, and can easily resist a very destructive level 0 hurricane.

PART.04 / SAFETY PERFORMANCE

The safety performance is relatively easy to understand, and two dimensions are mainly considered: if the house is a low-rise and facing the street, for the sake of safety, the selection of doors and windows should focus on the protective performance of doors and windows; There are children at home, in order to avoid the danger of baby climbing, the direction of the fan, the size of the fan and infrared recognition should be taken into account, and special attention should be paid to the safety performance of doors and windows.

PART.05 / Watertightness

Watertightness refers to the ability of closed exterior (doors) and windows to block rainwater leakage under the simultaneous action of wind and rain. This index is one of the three basic physical properties of doors and windows. It is divided into 6 levels. It is easy to find out if the water tightness of the doors and windows is good. For example, when it rains, the windows can leak water to the edges of the windows or even to the floor. This is obviously due to the poor watertightness of the doors and windows.

PART.06 / Airtightness

Airtightness refers to the ability of a window to prevent air from penetrating when closed. Generally speaking, it is divided into 8 levels. For example, on a windy day, there is wind in the windows of the home, and the wind passes through the window frame or sash. Or the bagpipes on the doors and windows of high-rise buildings are loud, it must be that the air tightness of the doors and windows is not good and does not meet the standards.

The performance of doors and windows includes sound insulation, heat insulation, safety, water tightness, air tightness, wind pressure resistance, etc., and a high-performance door and window can improve the comfort of the home environment. So a good door and window can bring a better and more comfortable life to your family!
