In all aspects of decoration, high-rise window sealing can be regarded as a big project. Because this project involves the risk of high-altitude work and glass installation, and the door and window market is mixed, there are problems such as uneven product quality and different industry standards.
In this issue, we will tell you some precautions about sealing windows on high floors. Combined with my own decoration experience, plus I went to the door and window store to learn while looking at the model, I summarized the "5 don't choose" principle to help you avoid pits
To seal windows on high floors, we should first consider the way the windows are opened. However, there is no explicit provision in the current effective national regulations (rather than local standards) that the use of outward windows in high-rise residential buildings is strictly prohibited. But according to the "civil building exterior doors and windows engineering technical standards provisions": seven floors and more than seven floors of civil buildings should not use the outer casement window, this is mainly because with the increase of building height, the wind load of the external window also increases, when the external casement window is affected by the wind, there will be the risk of falling off the fan.
At present, for high-rise window sealing, the best way to open is to use inward opening and tilting windows. If you don't mind that the sealing is not good enough, you can use sliding doors and windows, but the sash must have anti-falling measures.
High-floor window sealing, the choice of glass can not be sloppy, after all, glass occupies most of the entire area of doors and windows. Many people are particularly yearning for that kind of large floor-to-ceiling glass windows, but in fact, if it is a high-rise window, it is not recommended that you make floor-to-ceiling large glass windows.
First of all, it is for safety reasons, because in the standard design of doors and windows, the more and denser the window frames, the stronger the whole window will be. After the large floor-to-ceiling windows are installed, even if the glass is thickened, it may not be able to withstand the wind pressure faced by the upper floors, especially when there is a typhoon, the consequences can be unimaginable. Not to mention that the tempered glass itself also contains a 3% self-explosion rate, and it is not advisable to blindly pursue floor-to-ceiling large glass windows.
Then there's the issue of cost. The design of floor-to-ceiling large glass windows is adopted, so the glass should be thickened, the profile should be thickened, and the cost of all accessories should be increased, which is a point. There are also labor costs, hoisting costs, etc., in case of damage in the middle of the transportation, all kinds of costs and risks will increase. If it is not the scenery outside the window that is particularly worthy of you to make floor-to-ceiling large glass windows, then I personally recommend not spending this money.
Since doors and windows belong to customized goods, you will find that there is no unified standard for doors and windows, some 300 yuan, some 1000 yuan, in addition to the brand premium, in fact, are closely related to the quality of materials.
For example, in order to save costs, some manufacturers will use ** aluminum as the raw material for profiles, and the wall thickness of the profiles is often a few millimeters thinner than the national standard, and the glass is not double-layer insulating glass, but ordinary glass.
This is not a good buyer, there is no difference at all, from the naked eye, the doors and windows that are several times different look the same, but they don't know the cheap doors and windows, which means that the material is poor, the performance of the doors and windows is not good, and the service life is short.
When we choose door and window profiles for window sealing, it is best to choose broken bridge aluminum profiles with good thermal insulation effect, and the wall thickness reaches 1For more than 8mm, double-layer insulating glass or laminated glass with 3C certification mark is used, and the thickness of the air layer should be greater than 9 mm, and only single-layer glass or simple double-layer glass can be used. In addition, be sure to choose regular channels of big brand hardware accessories, there are many cheap "copycats" on the market, pay attention to identification.
Don't underestimate the insulating strips of doors and windows, which are an important part of the window and are used to block heat transfer between indoor and outdoor areas. Poor quality insulation strips may lead to poor insulation performance of windows and affect the comfort of living. Therefore, it is very important to choose a good quality insulation strip.
In the past, some unscrupulous merchants would use PVC insulation strips to act as nylon insulation strips, but now with the development and progress of the industry, there are very few PVC insulation strips, but you are likely to buy inferior nylon strips.
When choosing thermal insulation strips, you should look for the brand, imported brands such as Technoform, Ensinger, etc., domestic brands such as Youtai, Baotai, etc., to identify PA66 multi-cavity thermal insulation strips, all brand thermal insulation strips will be printed with logo.
High-floor window sealing must not be saved on hardware accessories, it is the heart of doors and windows, is the key accessories that affect the life of doors and windows. In addition to door and window handles, lock points, lock seats, clutches, corner devices, hinges, sliding braces, pulleys, etc. are all hardware accessories for doors and windows.
The cost of inferior miscellaneous hardware accessories is often about 50 yuan a set, if you put on any brand logo, it may be about 70-100 yuan, and the imported big brand hardware reaches 3500 yuan per set, the price difference between these hardware accessories is large, you can imagine how much greasy there is behind it.
First of all, the so-called "original hardware" is not credible, and some aluminum manufacturers do not produce hardware at all, but the hardware accessories are playing with its logo, which is often the hardware that the business itself finds a small factory to order, and the high-rise window sealing must identify the well-known domestic door and window hardware brand or imported brand. When the window is accepted, special attention should be paid to whether the hardware accessories are rusty, damaged, or the switch is not smooth.
The above are some small suggestions about the sealing of windows on high floors, I hope to help you!
