Which range of aluminum is best for windows?
When choosing the best aluminum for your windows, there is no one range that is universally best. Each aluminum alloy range has unique properties that make it more or less suitable based on specific application, climate, budget and design requirements. (κουφώματα αλουμινίου)
Here is the breakdown of the most relevant aluminum series for the use of residential and professional windows:
000 6000 Series - best All-Been Option
Ideal: Residential and Professional Windows
Key elements: magnesium + silicone
Why pick it up:
-
Excellent balance of strength, corrosion resistance and creativity
-
Ka, wa, weld and easy to finish (powder coating or anodizing)
-
Versatile and widely available
-
Judgment: a range of commonly used for window profiles due to its adaptability, efficiency and cost-effectiveness.
🔹 5000 series - Superior corrosion resistance
Ideal: a coastal or humid environment
Key element: magnesium
Why pick it up:
-
Exceptional resistance to corrosion, especially in salt or wet conditions
-
Weight ratio
-
Good weldability and medium formation
-
Judgment: One of the best choices if you live near the sea or in high humidity areas. It is worth a slightly expensive but added durability.
000 7000 range - maximum strength
Ideal for: Industrial Dyogic, Military or Aerospace-Grade Apps
Key Elements: Zinc + Magnesium
Why pick it up:
-
The highest stress power in the aluminum range
-
Used in high-load structural applications such as aircraft and heavy-duty equipment
-
Judgment: Although very strong, it is often very expensive for the use of unnecessary and typical home window. More suitable for specific architectural or high performance projects.
Which aluminum is the strongest?
The 7000 series, especially 7075 aluminum, is considered the strongest in commercial aluminum alloys. It is valuable for:
-
Mechanical power
-
Excellent fatigue resistance
-
Long -term durability under stress
However, alone strength does not make it the best choice for windows. For homes, a 6000 or 5000 series usually offers a more practical benefit by balance:
-
Cost
-
Ease of production
-
E -Periodical
-
Design
How to choose the best window for your home
The choice of the right window includes more than just choosing frame content. It's about the perfect material, opening system and glazing corresponding to your home style and display requirements.
Here is a guide to help you understand each key element:
1. Types of window material
The content of the window frame significantly affects its durability, insulation, aesthetics and maintenance requirements. Common window content includes:
🪟 Aluminum
-
Pros: durable, lightweight, corrosion resistant and attractive modern appearance
-
Cons: Managing heat easily - can reduce thermal performance (πόρτες ασφαλείας)
-
Solution: Use thermal break technology to prevent heat loss or gains while maintaining slim design benefits of aluminum, Improve Insulation
🌲 Wood
-
Pros: Excellent natural thermal insulation, warm and traditional look
-
Cons: Prone to moisture uptake, insects, and requires regular maintenance (painting, sealing)
-
Note: Unsuitable for damp or dirty conditions unless treated and maintained properly
🏗️ Other Materials (for comparison)
-
PVC (uPVC): Excellent thermal performance, low maintenance, but weighty frames
-
Composite: Blends materials like wood and aluminum for hybrid performance
-
Steel: As strong as possible and thin but expensive and less heat-efficient
Based on the merits and demerits of each material, you can decide on the basis of:
-
Your climate
-
Aesthetic taste
-
Budget
-
Willingness to maintain
-
Select 6000 Series aluminum for optimum overall balance of performance, efficiency, and price.
-
Select 5000 Series if your residence is in a beach or high-humidity area.
-
Leave 7000 Series for specialty applications where structural integrity trumps cost and ease of manufacture.
-
Always include thermal break technology in the selection of aluminum windows for improved energy efficiency.
-
Choose the opening system and glazing appropriate to your life style, interior planning, and climatic conditions.
