First, I think plastic window hardware accessories are easy to damage, there is not solid, loose off and so on.

A: If you choose a good hardware and windows, the design is reasonable, correct installation and use, no problem.

It is also often seen that there are no metal backings when tightened and there is not enough mounting strength.

Second, broken bridge aluminum window that is good?

A: The main energy-saving insulation, noise reduction and noise is better.

The aluminum alloy window of the thermal break bridge is an improved type that is introduced on the basis of the old aluminum alloy window in order to improve the thermal insulation performance of the door and window. The heat conduction of the aluminum is blocked by the reinforcement of the nylon partition into two parts inside and outside. The material and quality of the reinforced nylon spacers directly affect the durability of the thermal break aluminum alloy window.

Third, how to check the installation quality of doors and windows?

A: If the owner himself checks, it mainly depends on whether the air leakage (airtightness) leaks (watertightness), whether the switch is smooth, whether the hardware is flexible, the appearance does not touch the scratches, the glass is clean, as follows:

1. Window surface: The window frame should be clean, smooth, smooth, no scratches, bumps on the large surface, and there should be no open welding cracks on the profile.

2. Hardware: The hardware must be complete, the position is correct, the installation is firm, and the use is flexible. It can achieve its own function.

3. Glass seals: The contact between the sealing strip and the glass and glass notches should be smooth, and must not be crimped or grooved.

4. Sealing quality: When the doors and windows are closed, there is no obvious gap between the fan and the frame, and the sealing strip on the sealing surface should be in a compressed state.

5. Glass: The glass should be flat and securely installed. There should be no looseness. The single-layer glass must not be in direct contact with the profile. The inner and outer surfaces of the double-glazed glass should be clean. There should be no dust and moisture in the glass sandwich. The partition cannot be tilted.

6. Bead: The bead with seal must be tightly attached to the glass. There should be no visible gap between the bead and the joint. The joint gap should be less than or equal to 1 mm.

7. Scrapping material: Scrapping material should be closely connected with the window frame, sealed with caulking paste, and should not be shaken. The screw spacing should be less than or equal to 600 mm. Both ends of reinforced steel lined with inner lining should be firmly fixed with the opening.

8. Switch parts: Flat open, push-pull or rotate windows should be closed tightly.

9. The frame is connected to the wall: the window frame should be horizontal and vertical, and the height should be the same. The distance between the fixed pieces should be less than or equal to 600 mm. The frame and the wall should be connected firmly. The gap should be filled with elastic material, the surface seam should be sealed, and there should be no cracks. .

10. Drain hole: The position of the drain hole should be correct, but also smooth.

Fourth, how to maintain plastic doors and windows

A: 1, when the assembly plant door and window installation team to complete the installation of doors and windows, due to the wall decoration staff are not careful, often appear uneven thickness of the filling foaming agent or stick to the plastic doors and windows, sometimes, there are stubborn stains . At this point, we can:

A. Use a spatula to level out the convex part of the filling and sand it with a smooth paper.

B. If there is paint decoration, the same color paint can be used to handle the leveling.

C. Scour the surface of the profile with water to remove general dust.

D, stained with ethyl acetate scrub stubborn stains, and then scrubbed with water.

2, one of the advantages of steel doors and windows is basically do not need to repair, but considering that there are many improper use of plastic steel doors and windows profiles or poor processing quality, it is recommended that the user is best to repair and maintenance once every six months to a year. General inspection of the following five aspects:

A. Whether there is any crack in the profile weld of the door and window frame and the fan.

B. Whether the door or window fan has obvious deformation, warping, or sagging fan.

C. Check whether the sealing strips and the strips have contraction, deformation, and voids.

D. Whether the hardware accessories are broken, damaged or tight.

E. Whether the drainage hole is open or not.

Fifth, why the installation of aluminum alloy doors and windows is not strong, poor stiffness

A: 1, improper selection of doors and windows profiles, the size is too small, thin profile thickness.

2. The connection and fixing method of the door and window frame with the wall body is improper.

3. When the combined door and window is assembled, the structure is irrational, the connection is not firm, and deformation occurs after the force is applied.

Sixth, how to use steel

Answer: 1, plastic steel window information

Before selecting a unit of steel doors and windows, you must first obtain a quality inspection report for the plastic doors and windows, and check its four main indicators, namely hardness (HRR), low temperature drop hammer impact test, high and low temperature sleet change rate (the above three According to the provisions of GB8814-89 and the angular strength test (according to GB17793-89), whether the indicators meet the requirements. The above four indicators can all reflect the product quality of the steel doors and windows, and the products that are not processed according to the standard are not easy to meet the standards. In addition, these indicators are also more intuitive, and ordinary consumers can read it.

2, to observe the surface finish of steel doors and windows, whether there are obvious scratches, geometric dimensions are stable, see if there are cracks in the welding corner and so on.

3, window type selection of steel doors and windows

The choice of window type should be based on different regions, different climatic conditions to choose the appropriate model of steel doors and windows. For example, in the cold regions of northeast China, 50-60 type multi-chamber flat open double glass windows can be used. Because of the low temperature in cold regions, multi-chamber profile and double glass windows can enhance the sealing performance and reduce the thermal conductivity, thereby satisfying Insulation requirements. In the area south of the Great Wall and north of the Yangtze River, 60-85 series sliding windows are suitable. Because the area does not require thermal insulation as strictly as in the northeast. Jiangnan region should choose sliding window with small section profile and good watertight performance. In the northwest region, due to large wind and sand, there is a large temperature difference between day and night, so it is appropriate to use the 80-85 series double glass sliding window.

Seven, aluminum alloy doors and windows to buy?

A: First look at the materials. High-quality aluminum alloy doors and windows used in aluminum, thickness, strength and oxide film, etc., should comply with relevant national standards, wall thickness should be more than 1.2 mm, tensile strength of 157 newtons per square meter mm, yield strength to achieve each Square millimeters 108 Newtons, oxide film thickness should reach 10 microns. If it fails to meet the above criteria, inferior aluminum alloy doors and windows cannot be used.

Second, look at processing. High-quality aluminum alloy doors and windows, fine processing, installation stress, good sealing performance, switch freely. Inferior quality aluminum alloy doors and windows, blind selection of aluminum profiles and specifications, rough processing, and saw cutting instead of milling, not installed as required, poor sealing performance, switches are not comfortable, not only leakage of air leakage and glass burst phenomenon, but also To strong winds and external forces, it is easy to scrape or drop the push-pull part or the glass, destroying things and hurting people.

Then look at the price. Under normal circumstances, high-quality aluminum alloy doors and windows due to high production costs, the price is about 30% higher than inferior aluminum alloy doors and windows. Some aluminum alloy doors and windows made of aluminum profiles with a wall thickness of only 0.6-0.8 mm have much lower tensile strength and yield strength than the relevant national standards and are not safe to use.

What determines the price of steel doors and windows?

(1) Profile quality. Because of the anti-aging and anti-ultraviolet chemical composition of the high-quality plastic steel profiles, from the outside, the color should be blue and white, not white or milky white, which is generally considered by everyone. The low-grade plastic steel doors and windows have calcium content in the profile formula. More, so yellow in white, long time will become more and more yellow.

(2) Steel liner thickness. In order to reinforce the steel profiles, steel linings should be inserted inside the steel windows. The steel linings have two thicknesses of 1.2 and 1.5 (unit: mm). The national standard is 1.2 mm thick, which is enough for ordinary homes;

(3) Source of hardware. Whether the hardware is imported or domestic is also a major factor determining the price of doors and windows.

Nine, false too much, how to distinguish between genuine and fake conch windows

A: It mainly starts from the following four aspects:

(a) Profile color. The color of the real conch profile is blue-white; the color of the false conch profile is yellow in white.

(b) Whether or not there is a steel lining. True conch profiles have steel linings inside; fake conch profiles do not have steel linings. The presence or absence of steel lining is very intuitive from the perspective of the cut surface and cannot be seen from the outside. The way to distinguish is: Take a magnet and suck it against the profile.

(c) Protective film. True Conch's protective film is hot-pressed and there will be no small bubbles; false conch is hand-laid, and there will usually be small bubbles.

(d) security labels. Real Conch's anti-counterfeiting label is very clear, and it cannot be discolored with water. The fake conch's azimuth label is fuzzy and black, water wipe will fade, and some will even disappear;

Ten, how to identify the quality of steel windows

Answer: 1. During the renovation, since the window removal process will destroy the internal and external walls, it is better to replace the doors and windows first and then proceed to the next step.

. When buying a house, which brand profile should be used clearly, because the brand of the profile will determine the entire door and window in the door and window

In terms of quality, buyers should not be fooled by the vague concept of “high-quality plastic steel doors and windows” in the book.

2, when purchasing, must go to the formal building materials market, roadside stalls, its processing equipment, simplicity, accuracy and strength

There is no guarantee at all. In addition, the quality of the inner lining steel of the profile is poor, even without lining steel, and other accessories are also poor.

3, the appearance of plastic doors and windows should be blue and white. The color is too white or gray, indicating that the stable ingredients in the material are not

Enough, long time aging and yellowing.

4. Check if the hardware is flexible and smooth.

5. The sliding window of the window frame should have aluminum slides to facilitate its replacement.
