Never make this kind of balcony-sealing window. I am home improvement, and the property management calls down every day!

At present, whether it is high-rise or bottom-level house decoration, there will be a process of sealing the balcony. There are still many precautions for balcony sealing, but the premise of balcony sealing is to choose good materials. There are so many materials on the market now, which one should we choose? What are the precautions for balcony sealing?

First, the balcony sealing material?

1, common aluminum alloy

Advantages: suitable for any climate, strong anti-aging ability, good sealing performance and long service life;

Disadvantages: poor heat insulation, few colors to choose from, simple shape and few patterns;

What does 80/70/65/55 of aluminum alloy mean?

Numbers such as 80/70/65/55 on aluminum alloy refer to the width of the profile, and 80 represents the thickness of 80 mm The larger the number, the stronger the heat insulation capacity of aluminum material! Under normal circumstances, it is enough for our aluminum to choose a window frame with a thickness of more than 55mm! It's not cost-effective if it's too expensive. It's better to change materials!

2. Broken bridge aluminum alloy

Broken bridge aluminum alloy is an upgraded version of aluminum alloy material. Broken bridge here means heat insulation. Therefore, broken bridge aluminum is also called thermal insulation aluminum profile.

Advantages: heat insulation, fire prevention, air tightness, water tightness, corrosion resistance, good thermal insulation performance, not easy to deform and not fade, in short, it is superior to aluminum alloy materials in all aspects.

Disadvantages: the price is more expensive and the cost is higher.

Because of the aluminum alloy material, it is not heat-insulating and heat-insulating, and it costs electricity to turn on the air conditioner in summer or winter! Broken bridge aluminum alloy does not have this concern. Using the broken bridge aluminum alloy window can save 50% of heating and air conditioning electricity bills, and the photoelectric fee can make up the difference with aluminum alloy materials within two years!

PS: What does the broken bridge aluminum alloy merchant mean by 1.6 thickness?

The thickness of this material is 1.6mm, remember that it is the thickness of the material, not the overall width! Like aluminum alloy, the thicker the profile, the higher the price, and the better the insulation effect! The national standard of broken bridge aluminum alloy material is: the wall thickness should reach 1.2 mm, choose the appropriate price, and don't underestimate the difference of a few millimeters, and the difference is not small!

3. Plastic steel

Plastic steel window frame literally means: PVC plastic+steel, steel inner support, and high-strength antioxidant plastic outside. This combination has the strength of steel and the waterproof and thermal insulation properties of PVC. However, the size of plastic steel window is larger than that of aluminum alloy window, and the plastic may change color and deform, so it is generally not recommended to use it at home!

Advantages: fire prevention and corrosion protection, good heat insulation performance, good sound insulation and heat preservation performance, and low price;

Disadvantages: poor sealing, safety and anti-theft, and poor ventilation quality;

4. Prices of three window frame materials

The cheapest is plastic steel doors and windows, the price is 200-300 yuan/flat, and the double glass will not exceed 400 yuan. Mid-range aluminum alloy windows need 400-500 yuan/flat. At present, the most widely used broken bridge aluminum 500-700 yuan/Ping is not very expensive!

Note that you must go to a formal authorized building materials store to buy profiles. Don't be greedy and cheap to buy inferior brand goods. The window skeleton is sloppy, and the processing equipment of those small factories is simple, and the accuracy and strength are not as good as those of the big factories! Whether it can reach the standard is a question!

Second, the matters needing attention of balcony sealing

1, prioritize and define functions.

A slightly newer house has 2-3 balconies. Before decoration, distinguish the main balcony and the sub-balcony, and clarify the function of each balcony. Generally, the balcony adjacent to the living room and master bedroom is the main balcony, which should focus on leisure and fitness, and can be equipped with gym, tea room and so on. And the decorative materials of walls and floors should be consistent with the living room; The second balcony is generally adjacent to the kitchen or the room outside the living room and master bedroom, mainly for storing things, hanging clothes or visiting, which can be simpler when decorating.

2. Pay attention to the packaging quality.

Balcony packaging quality is the key to balcony decoration. Pay attention to its wind resistance and install it firmly. Seal it properly, or it will be unsealed if it leaks. The lower opening of the window frame is the easiest to leak water. Generally, a gap of 2 cm is reserved under the window frame and filled with special sealant or cement. If there is a windowsill, you should make an outward slope.

3. Pay attention to safety.

Most residential balconies are not designed for bearing capacity, and usually the bearing capacity per square meter does not exceed 400 kilograms, so it is necessary to know its bearing capacity when decorating the balcony. Decoration and storage should not exceed its load, and try to reduce overweight furniture to avoid danger. When sealing the balcony, try not to put the balcony out to occupy more space, which is not only dangerous, but also unsightly, and the property management department does not allow it.

4. Pay attention to waterproof and drainage treatment.

Many families set faucets and washing machines on the balcony, so that the washed clothes can be dried directly, or set vegetable washing pools on the balcony for kitchen use, which requires that the waterproof layer and drainage system on the balcony floor must be done well. If the drainage and waterproof treatment is not good, there will be water accumulation and leakage.

Balcony closure is a major event in decoration, so we should pay attention to safety issues when closing the balcony, and don't tear it down casually, especially where the load-bearing wall is involved. After all, the premise of decoration is to ensure the safety of the home.
