1.Core Features of Aluminum Alloy Windows
Strong wind pressure resistance
Adopting high-strength aluminum alloy profiles (such as 6063-T5 alloy), the wind pressure resistance reaches the national standard GB/T 7106-2019 level 9 standard (highest level), and can withstand typhoons above level 12.
The profile wall thickness is ≥2.0mm, far exceeding the 1.4mm standard of ordinary doors and windows, ensuring structural stability.
Excellent sealing performance
Multi-channel sealing design (EPDM rubber strip + silicone sealant), air tightness reaches national standard level 8 (highest level), water tightness reaches level 6, effectively preventing rainwater leakage.
Sound insulation performance reaches 35-40 decibels, reducing urban noise interference.
Heat insulation and energy saving
Equipped with thermal insulation strips (PA66+GF25), the heat transfer coefficient K value is ≤2.5W/(m2·K), which saves more than 40% energy than ordinary aluminum alloy windows.
Optional Low-E insulating glass (such as 6+12A+6 double silver Low-E) can be used to further reduce heat conduction.
Strong corrosion resistance
The surface is anodized or fluorocarbon sprayed, and the salt spray test is more than 5,000 hours, which is suitable for coastal or high humidity environments.
The service life exceeds 30 years and the maintenance cost is low.

2. Advantages of House Aluminum Fixed Windows
High safety
The fixed design has no opening fan, eliminating the risk of falling from high altitude, and complies with the safety regulations of high-rise buildings.
Aluminum alloy material is non-flammable and meets fire protection requirements (fire resistance limit ≥1 hour).
Beautiful and durable
Narrow frame design (visible surface width ≤50mm) increases the lighting area (light transmittance ≥80%).
Surface treatment processes are diverse (such as wood grain transfer, metal brushing), suitable for modern, industrial and other architectural styles.
Environmental protection and energy saving
The recyclability rate exceeds 95%, which meets green building standards (such as LEED certification).
Thermal insulation performance reduces air conditioning energy consumption and reduces carbon emissions.

3. Application scenarios of Aluminum Fixed Windows
Super high-rise building curtain wall
Such as Shanghai Tower, Burj Khalifa in Dubai, etc., aluminum alloy fixed windows are used as curtain wall units, taking into account both lighting and structural safety.
Commercial complex
Used for facade decoration of shopping malls and office buildings to enhance the transparency and commercial value of buildings.
High-end residential
Villas, large flats and other projects use large-area fixed windows to create a 270° viewing field.
Special environment buildings
In corrosive environments such as coastal areas and chemical plants, aluminum alloy fixed windows have significant weather resistance advantages.
4.Standardized installation steps
Measurement and layout
Use a laser level to determine the position of the window frame, and the error is controlled within ±2mm.
Review the opening size (width/height deviation ≤5mm, diagonal deviation ≤8mm).
Window frame fixing
Put the window frame into the opening and temporarily position it with a wooden wedge.
Fix it with stainless steel expansion bolts (M8×80mm), with a spacing of ≤500mm, to ensure that the verticality deviation is ≤2mm/m.
Gap treatment
Fill the gap between the window frame and the wall with foam glue (expansion rate ≤30%), and seal the outside with weather-resistant sealant (such as silicone glue).
Gap depth ≥10mm to prevent cracking of the glue.
Glass installation
Use mechanical suction cups to install hollow glass (thickness ≥24mm), and the glass embedding depth ≥15mm.
Seal the glass with glue all around, and the glue seam width ≥5mm.
Acceptance test
Spray test (water pressure ≥0.3MPa) to check leakage, and no leakage for 15 minutes is qualified.
Opening and closing force test (fixed windows do not need this, but the firmness of the fixings needs to be checked).

5. Data-based benefit analysis
Cost comparison: The initial investment is 20%-30% higher than that of ordinary plastic steel windows, but the service life is extended by 2 times, and the life cycle cost is reduced by 35%.
Energy-saving effect: Aluminum alloy fixed windows can save air conditioning costs every year.
Construction efficiency: Modular design increases the installation speed by 40%, and the installation time of a single window is ≤1 hour.
