Wind pressure resistance Level 9 can only withstand Class 9 typhoons? Buy doors and windows, these performance parameters are recommended to understand first.
When buying door and window products or browsing doors and windows online, house owners should have seen these performance parameters, such as air-tightness level 8, water-tightness level 6, wind pressure resistance level 9...
Decoration “rookie” may be half-aware of these data, many customers in the Skyland doors and windows when consulting said "wind pressure resistance 9, refers to can resist 9 typhoons?" Now the typhoon is the highest level 17, can this door and window be carried?" Wait a while, the wind pressure resistance of doors and windows is not so simple to understand.
In view of the several major properties of doors and windows - air tightness, water tightness, wind pressure resistance, sound insulation, thermal insulation, for ordinary owners belong to the knowledge blind area, owners in the purchase of doors and windows these performance parameters also look in the clouds, today we will do a simple analysis to help you better understand the doors and windows products.The major performance of doors and windows, it is the guarantee of home comfort, but also the bearing of room safety, so it is necessary to understand the basic performance of doors and windows.
Wind pressure resistance
The wind pressure resistance of doors and windows refers to the ability of closed doors and windows to not be damaged and dysfunctional under the action of wind pressure. In the door and window system, the wind pressure resistance is divided into 9 levels, the higher the level, the stronger the wind pressure resistance.Regarding the previous owner's mention of "wind pressure resistance level 9, does it mean that it can resist a level 9 typhoon?" In this question, we need to understand that the wind pressure performance level is not equivalent to the typhoon rating. The wind pressure resistance of doors and windows is 9, which means that they can withstand wind pressure of more than 5000pa, which is almost an indicator of a 12-level typhoon.
The water-tightness of doors and windows refers to the ability to prevent rainwater leakage when wind and rain act at the same time under normal closing. The water-tightness of doors and windows can be divided into 6 levels, and the higher the same grade, the stronger the waterproof performance.We have emphasized in many articles that we should pay attention to the water-tightness of doors and windows, especially in the coastal cities, there are many rainy seasons and typhoons, only by choosing doors and windows with superior watertight performance can we effectively prevent rainwater from invading the internal structure of doors and windows, and ensure the service life and home experience of doors and windows.
Performance The air-tightness of doors and windows is the ability to prevent air penetration in the normal closed state. The air-tightness performance is directly related to the cold air penetration heat loss of doors and windows.The air-tightness of doors and windows is divided into 8 levels, the higher the grade, the smaller the heat loss, and the more prominent the energy saving effect.
Sound insulation performance
The sound insulation performance of doors and windows can be described as "golden oil" performance, whether it is a southern or northern city, a city or a village, a community or a self-built house or a high-end villa, the sound insulation performance of doors and windows is the basic configuration.Sound insulation performance refers to the ability of doors and windows to weaken sound. Generally speaking, the air sound insulation performance of doors and windows can be divided into 6 levels, the larger the level, the better the sound insulation performance, and the sound insulation performance is 6 levels of doors and windows, which can effectively maintain the sound of the living room at about 35 decibels.
Thermal insulation performance
The thermal insulation performance of doors and windows refers to the ability of window impedance to transfer heat from the high temperature side to the low temperature side under the condition that there is an air temperature difference between the two sides of the window. Thermal insulation performance is divided into 10 levels, the higher the grade, the smaller the K value, the better the thermal insulation performance, so the cold northern city, the door and window selection need to focus on its thermal insulation performance.
Through the above introduction,I think we already have a basic understanding of the performance parameters of doors and windows. When applied to the actual door and window selection, small partners can choose according to the actual situation and geographical location "according to local conditions", such as the southern coastal cities to emphasize the wind pressure resistance of doors and windows, the northern cities to the doors and windows of the insulation performance, street-facing houses, doors and windows sound insulation performance is the main reference index.
