Sealing balconies is a high-frequency requirement for home decoration, which can expand the usable area, improve safety, prevent dust and sound insulation, and beautify the home. But when sealing balcony pits, the water depth is too deep: the materials are inferior, the installation is not standardized, there is water and air leakage, and there is no door for after-sales service... If you want to seal well and use it for a long time, you must choose a professional brand for door and window customization - Lansi System Doors and Windows.
There are many high-rise residential buildings, and the first factor in sealing balconies is safety. The doors and windows of the Lansi system are made of 6060 T66 ultra high precision aluminum, with a wall thickness of over 1.8mm and a maximum wind pressure resistance level of 9, which can withstand strong winds during typhoons. The window adopts a multi-point locking structure and a pin injection process, with high overall strength, anti falling, anti-theft, and anti shaking, making it safe for high-rise families to use.
Traditional balcony windows either have poor sliding seals, external windows pose safety hazards, or internal windows take up space. Lansi specializes in designing the 80 series inverted sliding windows for enclosed balconies, which are the sixth generation mature technology and cost 20 million yuan for research and development. After 20 years of iteration, they do not occupy indoor space when opened, do not bump furniture or heads, have soft ventilation, and are safer for children and the elderly to use.
In terms of sealing and sound insulation, the Lansi Sealing Balcony Solution adopts a multi pass sealing structure, with EPDM vulcanized welding rubber strips and PE wave cotton insulation filling. The highest air tightness is 8 levels and the highest water tightness is 5 levels. It does not leak water in rainy days or in strong winds. Glass can be selected with three glass and two cavity Low e filled argon gas, with a sound insulation of up to 45dB. After sealing the balcony, indoor noise is significantly reduced and dust is greatly reduced.
In terms of energy conservation, the Lansi system has excellent window insulation, reducing heat loss in winter and blocking outdoor heat in summer. The energy consumption of air conditioning and heating is reduced by 30% -50%, making long-term use more economical. The extremely narrow edge series of enclosed balconies features flush frames and fans, a wide view, and a high glass to ceiling ratio, making the small balcony appear larger and the living room brighter. It is suitable for various decoration styles such as modern, light luxury, minimalist, and French.

Many homeowners are concerned about the additional cost of sealing off balconies and the falsification of materials. Lansi insists on transparent pricing, with clear information on main materials, auxiliary materials, hardware, and installation fees, without low price diversion or malicious addition. All aluminum, glass, hardware, and insulation strips are genuine and can be inspected on-site. They support third-party testing and truly achieve quality transparency.

Sealing the balcony is not only about installing windows, but also about creating a comfortable and practical living space: it can be used as a leisure area, storage area, study room, and children's activity area, adding practical functions to the home.
