Enclosed balcony is a very important link in the early stage of decoration, which is directly related to the quality of living in the later period.
However, many people are willing to spend a lot of money on main materials and furniture, but they are quite casual when sealing the balcony.
It was only after I moved in that I discovered a series of problems such as leaking windows, no sound insulation, and difficulty in use. It was too late!
Today we will share some useful information about sealing the balcony!
Friends who are preparing to decorate can refer to it when sealing the balcony. one time!

There are many benefits to sealing the balcony!
1, safety
sealed balcony can prevent thieves from the outside, and can prevent naughty children from climbing and falling from the inside. Recently, there have been many news about falling from high altitude, so safety cannot be underestimated.
2, clean
The balcony can be sealed to prevent dust, rain, smog, and enhance thermal insulation.
Especially for us in Zhengzhou, it can also prevent the harsh effects of smog and sandstorms, reduce the number of cleanings, and keep the room clean.
3, soundproofing
sealing the balcony can greatly reduce external noise pollution and ensure a comfortable home environment. Especially for a house facing an elevated building, the traffic outside the window will definitely keep you awake at night if you don’t isolate it!

4. Increase indoor space
Relevant regulations stipulate that if the balcony is not sealed, half of the area will be given away. Many developers use this as an excuse to make the balcony area larger as an additional benefit!
After sealing the balcony, the balcony can be turned into a small garden, study room, sun room, laundry room and other functional spaces. Making good use of the balcony is equivalent to having an extra room in the home!
Calculated based on current housing prices, this is equivalent to earning tens of thousands, which is also valued by many people!

Let’s get to the point.
enclosed balcony mainly involves the following parts:
profiles, glass, hardware, accessories
profiles : Simply put, it is the frame, which is divided into plastic steel, aluminum alloy, broken bridge, etc.
Plastic steel window : Plastic steel window frame is plastic (PVC) + steel. The steel support and the outer layer of high-strength antioxidant plastic are low in price. Plastic steel materials are more brittle and heavier than aluminum alloys. Poor fire resistance. It has basically withdrawn from the market.
Ordinary aluminum alloy windows: have good weather resistance and anti-aging capabilities, but the thermal insulation is not as good as other materials.
For most owners, material must be broken bridge aluminum
Simply put, broken bridge aluminum is an aluminum alloy with plastic spacers in the middle, which greatly slows down the heat conduction between the aluminum materials.
Its sound insulation, heat preservation, pressure resistance, air tightness (no dust will get in when it is windy) and water tightness (no water will flow into the room when it rains).
Aluminum material: To choose the original aluminum produced by regular manufacturers, the cross section looks smooth and bright.
We see many brands in the market. 60/80/90/100 and other series refer to the width of the window frame. Normally 70-80 is enough. It is recommended that the wall thickness of aluminum materials be above 1.4mm.
glass : Choose a good glass original brand such as Luobo , CSG , etc. The color is positive and thick, the light transmittance is better, must bear the 3C mark.
Nowadays, double-layer insulating glass is more commonly used. If you want good thermal insulation effect, you can choose three glass and two cavities; if you want good sound insulation effect, you can choose laminated insulating glass. Those who are not short of money can choose the heat-insulating and light-transmitting LOW-E glass .
Hardware:
Hardware includes handles, actuators, locking points, hinges, wind braces , the most common hardware brand should be Jianlang . Better brands include Noto Root, Hopo, Stanford, etc.
Hardware is related to the service life of the entire window and should not be underestimated. Look for the above brands when purchasing.
In addition, it is recommended to install an anti-fall rope to prevent accidents in bad weather.
auxiliary materials : mainly refers to the sealing strips, structural glue and other materials required for installation.
insulation strips must choose PA66 glass fiber nylon insulation strips, which have long life and are resistant to high temperatures. The wider the width, the better the heat insulation performance. sealing tape uses automotive-grade EPDM tape, which is anti-aging, has good elasticity, and is not easy to harden or break.
The quality of window sealing structural adhesive is crucial. Especially the glue applied on the outside is prone to aging after being exposed to wind and sun, and will crack and leak over time.
so be sure to choose the brand's structure glue . Foreign brands include German Wacker , Silicon Treasure, Dow Corning (there are many fakes), and domestic brands include Sanhe, Antai, Baiyun, Zhijiang, etc.
requires sellers to use branded structural glue during installation, but most merchants will not use too good glue due to cost considerations.
is really not enough, it would be more reliable to provide it yourself.

three-point product, seven-point installation.
Sealing the balcony requires careful construction, and the handling of details is more important. Otherwise, problems such as leakage in rainy days, loose sealing, etc. will affect the quality of home life in the future.
Glue and seal :
First, apply exterior wall structural glue at the gap between the outside of the window frame and the opening;
Second, apply foam glue to the joint between the inner window frame and the opening of the balcony for fixation and sealing, and finally use Glass glue sealing;
Third, glue is applied to seal the joints such as the corners of the window frame.
Waterproof slope
After installing the window, make waterproofing on the outer edge where the aluminum and concrete contact. It is best to use flexible waterproofing.
After the waterproofing is completed, ask the bricklayer to use cement to make a gentle slope on it. The inside is high and the outside is low. The rainwater will flow down without water accumulation, reducing the risk of water leakage.
The final summary is as follows:
❶ If the budget is sufficient, it is recommended to replace all the doors and windows provided by the developer to improve the quality of life
❷ The outer openings of the windows should be made with gentle slope + waterproofing to prevent water leakage in rain and snow
❸ Foaming agent , structural glue Buy it yourself , the quality provided by the merchants is average
❹ Install and design according to the requirements provided by the property
❺ If you have enough budget, choose a first-line brand, but the brand premium is high. You can also choose second-tier domestic brands as normal.
❻ Read the quotation in detail, focus on the material, configuration, and hardware. Find several more companies to compare prices. Don’t pursue performance too much and act within your capabilities.
❼ Doors and windows are three-point products and seven-point installation. Let the merchant designate a professional master to install it, and conduct careful acceptance after completion.
We need to be careful when sealing the balcony. We can choose different forms and materials according to the actual situation, but we must have quality-guaranteed products to create a safe and comfortable harbor for our families.
