1. Aluminum Windows: Longest Lifespan (30-50 Years)

Aluminum Windows Advantages:

Strong Corrosion Resistance:The Surface Oxide Layer (Via Anodizing Or Powder Coating) Prevents Rust, Making Them Ideal For Humid Regions (E.G., Coastal Cities).  

Resistant To Deformation:Metal Material Does Not Warp Or Crack Due To Temperature Or Humidity Changes, Unlike PVC Or Wood.  

Low Maintenance:** No Need For Painting; Only Regular Cleaning Is Required, And They Resist Aging Over Long-Term Use.  

Aluminum Windows Note:

Standard Non-Thermal-Break Aluminum Windows May Experience Sealing Issues Under Extreme Temperature Fluctuations, But Thermal-Break Aluminum (With Insulation Strips) Can Mitigate This.  

2. PVC (Plastic Steel) Windows: Moderate Lifespan (15-25 Years)

Plastic Steel Advantages:

Lower Cost, With Better Insulation Than Standard Aluminum Windows.  

Short-Term Resistance To Rust And Corrosion.  

Plastic Steel Disadvantages:

Prone To Aging:PVC Material Becomes Brittle And Yellows Under Prolonged UV Exposure (Sunlight), Especially Low-Quality PVC Windows, Which May Warp Or Fail To Seal Properly Within About 10 Years.  

Low Strength:Weak Wind Resistance In High-Rise Buildings Or Windy Areas, With Hardware Components Loosening Easily.  

Heat Sensitivity:High Temperatures (E.G., Rooms With Strong Afternoon Sun) Can Accelerate Deformation.  

3. Wooden Windows: Variable Lifespan (10-40 Years, Depending On Maintenance) 

Wooden Windows Advantages:

High Aesthetic Appeal, Suitable For Vintage Or High-End Decor.  

Best Natural Insulation Performance.  

Wooden Windows Disadvantages:

Vulnerable To Moisture And Pests:Prone To Rot, Mold, Or Termite Damage In Humid Regions, Requiring Regular Anti-Corrosion Treatment.  

High Maintenance: Needs Sanding And Repainting Every 3-5 Years; Otherwise, Cracking And Warping May Occur.  

Expensive:High-Quality Hardwood (E.G., Teak) Windows Are Costly, And Maintenance Expenses Far Exceed Those Of Aluminum.  

Overall Ranking (Lifespan):

Thermal-Break Aluminum (40-50 Years) > Standard Aluminum (30-40 Years) > High-Quality Wooden Windows (20-40 Years, With Maintenance) > PVC Windows (15-25 Years)  

Purchasing Recommendations:

For Durability + Low Maintenance:Choose Thermal-Break Aluminum (Especially For High-Rises, Coastal Areas, Or Regions With Large Temperature Swings).  

Limited Budget + Short-Term Use: PVC Windows (Suitable For Low-Rise Buildings In Temperate Climates).  

Aesthetics + Willingness To Maintain:Opt For Treated Hardwood Windows (E.G., Nordic-Style Villas).
