Choose the right door and window, all these troubles are saved!

As one of the very important links in the process of house decoration, doors and Windows not only affect the overall visual effect, but also meet our requirements for room comfort, warmth and safety. Doors and Windows integrate profiles, hardware, glass and auxiliary materials and other materials, the design needs to consider aesthetics, structural mechanics and photothermal energy conduction control, noise control, wind pressure resistance, air tightness, water tightness, ease of use, durability and weather resistance and many other factors.

Products need to consider a lot of factors, while the market specification is very poor, so you in the choice of doors and Windows, facing a lot of misunderstandings and traps, next, I will combine their own experience, give you some suggestions for choosing doors and Windows.

Selection of Windows and doors preferred "broken bridge aluminum"

When you buy aluminum alloy doors and Windows, businesses may recommend broken bridge aluminum. Because aluminum alloy is a good conductor of heat, heat insulation is too poor, affecting comfort and environmental protection. Before the broken bridge technology came out, the aluminum alloy basically withdrew from the selection of doors and Windows due to its thermal insulation problem, and the appearance of the broken bridge technology saved the aluminum alloy doors and Windows. Therefore, in the decoration process, unless the silver is too tight, it is generally recommended to use the broken bridge aluminum doors and Windows, in addition to their own comfort, energy saving and reducing energy consumption is also very important.

Selection of bridge aluminum depends on the "system"

There is also a concept of system doors and Windows in the broken bridge aluminum doors and Windows, which was first proposed by Germany Schuco. Generally speaking, the system doors and Windows have been greatly improved in terms of air tightness, water tightness, sound insulation, structural strength and durability compared with ordinary broken bridge aluminum doors and Windows. Some of the more famous systems are Schuco, Smart, Renus, Aluk, Hydro, and Noto. These are generally foreign system design, in the domestic mold production, the domestic system is more famous brands are Ledao, Canon and Beclo and so on. There are many doors and Windows companies designed their own systems.

The way to judge the quality of a system is mainly to look at the section of the profile sample Angle. Usually a broken bridge section and the tightness of the sealing strip can reflect the quality of a system. The following points are easier to help you:

1) There are three rubber strip seals between the system doors and Windows, opening doors and door frames.

2) The system door and window glass installation will not be made of silicone, are the use of glass inside, glass outside two rubber strips.

3) The glass press line of the system door and window cannot appear outdoors. As shown in the picture below:

In terms of price, taking 60 system Windows as an example, the general price of domestic systems ranges from 1200-1800. Half of those abroad are between 2000 and 3000.

The choice of doors and Windows also depends on the opening method

How to choose the way to open the doors and Windows of the house is also very important! The common window opening methods are: push and pull, outside opening, inside opening, upside down, etc.

Push-pull window is very popular before, the price is cheap, does not take up space, easy to use. However, the main problem of the sliding window is that the sealing is not good, it is easy to leak air and water, and the sound insulation performance is very poor. The outer opening window is also a more used window type, the main feature is that it does not occupy the indoor space, but due to the safety risks of the outer opening window and the risk of falling from a height, there are few uses of the outer opening window in foreign countries, and China's norms also stipulate that buildings above 7 floors cannot use the outer opening window.

Here, I recommend that you install the inside opening inside the window, because the inside does not occupy the indoor space, the curtain can open and close freely, the lifting hanger will not conflict with the window sash; Children can play freely without worrying about hitting their head or body into a window corner or falling out of a window; When the indoor ventilation is natural, the wind is blown from the side of the window, not directly into the body, feeling more comfortable; When the wind is light, the rain will only splash on the glass and not splash into the room. Inward opening and inward reversing Windows began to be popular from Europe, and then spread to China, has become a standard product of high-end Windows.

In general, the choice of door and window hardware in the terminal retail link:

Most casement Windows of foreign brands are around one thousand yuan. The door hardware is more expensive, the door hardware requirements are relatively high, the gap between various brands is relatively large, we can compare more when choosing, not afraid of not knowing the goods, afraid of goods than goods

The details of doors and Windows cannot be ignored

1. Look at the Angle

As we all know, the final quality of doors and Windows and the processing capacity of the processing plant has a relatively large relationship, one of the important indicators is the Angle. The connection of two profiles at the corner of a good door and window is connected with aluminum corner code, and then the profile and corner code are extruded together with the corner machine, and then the two-component glue is injected into the hole to cure the corner code frame material together. Commonly used low quality practices are: no corner code splicing, corner code does not play curing glue, or it is a bit on the mouth to deceive consumers. In addition, you can also judge the quality by touching the stitching of the group Angle with your hand, and the smoother the group Angle processing quality is, the better.

2. Look at the rubber strip

In order to ensure the sealing of doors and Windows, the system doors and Windows use a large number of rubber seals, good seals must be elastic, black and bright color and not easy to deformation. Glass frame, good doors and Windows are the use of rubber strips, there are many manufacturers are artificial glue. This is not standard good door and window practice.

3. Look at hardware

For doors and Windows, hardware is the most representative thing, so many doors and Windows factory selling points are also in the hardware. The quality of hardware mainly comes from reasonable design, proper materials and fine processing. In general, we recommend you to use good hardware and handle.

4. Look at the glass

Glass has always been a weak link in home decoration doors and Windows, occupying 80% of the entire door and window area, and playing an absolutely important role in the realization of the function of doors and Windows. Many door and window manufacturers will avoid talking about glass, the main reason is that most processing plants are small factories.

The main functions of glass are thermal insulation performance, sound insulation, safety, anti-smashing and isolation of ultraviolet rays, etc., glass after processing, can get a lot of additional functions, but at present, these technologies are only some big factories can master. Glass industry more famous brands are: Yao PI, South glass, Xinyi, Taibo. Here are some points to remind you:

First, heat preservation and insulation mainly rely on low-e and hollow to achieve, low-E glass is divided into online and offline, offline low-E performance from LOW to high is divided into single silver, double silver and three silver, online low-E in performance is about equal to single silver. Under normal circumstances, the three-glass and two-hollow ordinary glass has not used LOW-E single-cavity glass to save energy;

Second, the hollow does not increase the sound insulation effect, and the heat insulation is mainly achieved by the sandwiched film in the middle.

So how to tell if LOW-E glass is used? Generally speaking, the LOW-E film is on the inside of the insulating glass outdoor piece (the second side), and carefully viewed from the side, you should be able to see a light layer of blue or gray film. In addition, I have a unique trick, use a lighter, close to the glass to look at the flame, a flame will have three shadows. On the side with the LOW-E film, the third flame shadow is pale blue, and the others are red. The three flames of ordinary glass are red, and the third flame color is only very light, and can not be seen when the light is bright. Look at the picture below:

Above is plain glass

Above is Low-E glass

Finally, let me say again, recently launched on the market self-cleaning glass scrub-free doors and Windows, through the integration of glass technology and door and window technology, so that a door and window in addition to customized aluminum color according to the needs of the owner, the most important thing is to have no scrubbing, isolation of 99% ultraviolet light, sound insulation 41 decibels, double silver energy-saving LOW-E and a certain anti-smashing and anti-crushing ability, Can maintain the integrity of the glass after the glass is broken.

5. Look at colors

Door and window colors can also be customized. At present, in addition to supporting the surface treatment of various colors on the market, it can also be made into wood grain shape, adding metal powder to increase metal texture and other means. The market recognition is relatively high is the aluminum alloy products, generally fluorocarbon spraying, powder electrostatic spraying, anodizing and surface coating and so on. Powder spraying is cheap, but it meets the most requirements. In addition, powder spraying in the interior to do wood grain can also; In the acceptance, in addition to meeting the individual needs, the acceptance should also pay attention to the surface spray quality, color difference, scratch and paint off and other unqualified phenomena.

The cost of color customization is generally charged according to the complexity of color processing, generally the starting amount of a color is more than 40 square meters, and the price per square meter ranges from 40 to 200 yuan.
