It is an ideal choice for doors and windows that balance practicality and decoration.
Core Structure and Material Selection
1. Overall Structural Design
The product adopts an integrated structure of "aluminum alloy profile frame - glass assembly - sealing system - hardware components", with a structural design that balances mechanical stability and ease of use:
1. Aluminum alloy profile frame: The main frame is made of high-precision insulation aluminum profiles or ordinary aluminum profiles, with a multi-chamber structure design, with a number of chambers ≥ 3, effectively enhancing insulation and structural strength; the frame joint areas are reinforced with angle brackets + joint glue, with a verticality deviation ≤ 2mm/m, ensuring no deformation or loosening over a long period of use.
2. Glass system: Standard double-layer insulating glass (5 + 12A + 5mm), optional triple-layer insulating glass (5 + 12A + 5 + 12A + 5mm) or Low-E insulating glass, the glass edges use butyl glue + polysulfide glue double-layer sealing, the inert gas filling rate ≥ 90%, effectively blocking heat conduction and noise transmission; special scenarios can be configured with laminated safety glass (PVB film thickness ≥ 0.76mm), with excellent impact resistance, and no splash risk after breaking.
3. Sealing system: Uses EPDM (triple rubber) sealing strips, with characteristics of high temperature resistance (-40℃~120℃), anti-aging, and lasting elasticity, forming multiple sealing structures between the door frame and door panel, the glass and aluminum profile, completely blocking the path of air and water penetration; the drainage system adopts a concealed design, equipped with anti-backflow drainage holes and filters, ensuring rapid drainage of rainwater and avoiding water leakage.
4. Opening mechanism: Includes three mainstream opening methods: internal opening and internal inversion, external opening and upward suspension, and bidirectional sliding opening:
- Internal opening and internal inversion: Combines internal ventilation and internal inversion micro-ventilation functions, avoiding rainwater from entering the room, and facilitating glass cleaning;
- External opening and upward suspension: The opening panel opens outward upwards, saving indoor space, with uniform ventilation, and high safety;
- Bidirectional sliding opening: Can open inward or outward, with an opening angle ≤ 90°, equipped with limiters to prevent excessive opening.

FAQ：
1. Which is better, aluminum alloy sliding windows or casement windows?
Both have their own advantages. You can choose based on your needs. The sealing performance and sound insulation and heat insulation effect of the casement windows are better. The opening method is flexible (internal opening, external opening, internal opening and internal reverse), and the ventilation efficiency is high. They are suitable for residences and office buildings that require high living comfort; the sliding windows have the advantage of not occupying space during opening, simple operation, and more affordable prices, making them suitable for large-span spaces such as balconies and passageways.
2. What is the core difference between insulated aluminum alloy casement windows and ordinary aluminum alloy casement windows?
The core difference lies in the heat insulation performance. The insulated aluminum alloy profiles are separated from the aluminum alloy's heat conduction path with insulation strips in the middle, which can significantly reduce the exchange of indoor and outdoor heat, providing better insulation in winter and better heat preservation in summer, with remarkable energy-saving effects; ordinary aluminum alloy profiles have an overall metal structure, with fast heat conduction and poor heat insulation performance, making them more suitable for places with no special requirements for insulation.
3. Can the glass of aluminum alloy casement windows be replaced?
OK. If the glass is damaged, fogged up, or requires upgrading (such as replacing with Low-E insulating glass or laminated safety glass), contact a professional to remove the hardware components and sealant strips and replace them with the same specifications of glass. Note that during the replacement process, ensure the glass fits well with the frame groove and reapply the sealant to avoid affecting the waterproof and soundproof effects.
4. What are the causes of water leakage in aluminum alloy sliding windows? How to solve it?
There are three common causes: first, the drainage holes are blocked, preventing rainwater from draining in time; second, the sealing strips are aging, broken, or not compacted during installation; third, the foaming agent or weather-resistant sealant between the window frame and the wall has cracked. Solution: Regularly clean the drainage holes; replace the aged sealing strips and compact them again; remove the old sealant at the cracked area and reapply foaming agent and weather-resistant sealant.
5. Can the hardware components of aluminum alloy sliding windows be upgraded? How long is their lifespan?
Yes, they can be upgraded. For example, replace the ordinary hardware with stronger bridge aluminum-specific hardware, or install child safety locks, anti-drop ropes, etc., to enhance safety and convenience. Qualified hardware components (made of stainless steel/zinc alloy) can have a lifespan of 10-15 years under normal use and regular maintenance.
6. Are aluminum alloy sliding windows suitable for high-rise residences?
Not recommended. High-rise outward-opening windows have safety hazards. During strong wind conditions, the window sashes are prone to be blown off, and there is even a risk of falling. High-rise residences should prefer inward-opening and inverted-type sliding windows, which are convenient for ventilation and cleaning the glass, and can effectively avoid the risk of falling objects from heights, in line with the installation specifications for windows in high-rise buildings.
7. Will the color of aluminum alloy sliding windows fade? How to clean and maintain them?
High-quality aluminum alloy profiles are treated with powder coating, fluorocarbon coating, or wood grain transfer, with strong resistance to ultraviolet rays and corrosion. Under normal use and regular maintenance, they will not significantly fade within 10-20 years. Clean the profiles and glass with a damp cloth. Avoid using strong acid and alkali cleaning agents; add lubricating oil to the hardware components once every six months to keep the opening smooth.
8. What is the relationship between the wind pressure resistance performance of aluminum alloy sliding windows and the profile wall thickness, structural design, and hardware load-bearing capacity?
The thicker the profile wall (bridge aluminum main profile ≥ 1.6mm), the more cavities there are, the stronger the deformation resistance; combined with high-strength hardware components and a reasonable installation and fixation method (such as expansion bolt spacing ≤ 600mm), it can further enhance the wind pressure resistance level, suitable for areas with strong winds such as coastal and high-rise buildings.
9. Can aluminum alloy sliding windows be customized in size? What is the maximum size of the sash?
Yes, they can be customized. The width of a single sash is 500mm-1200mm, and the height is 800mm-2100mm. The width of a double sash can reach 2400mm. If a larger sash is needed, upgrade to thicker profiles and heavy-duty hardware components. At the same time, consider the load-bearing capacity of the building opening to avoid affecting the stability of the window.
10. What is the sound insulation level of aluminum alloy sliding windows?
The standard sliding window with 5+12A+5mm insulating glass has a weighted sound insulation value of ≥ 30dB, which can effectively block traffic and street noise. If upgraded to triple insulating glass (5+12A+5+12A+5mm) or laminated insulating glass, the sound insulation value can reach over 35dB, suitable for areas with severe noise pollution.
