When installing aluminum windows and doors, choosing the right aluminum gauge is the most important decision. Many people focus only on design, but the strength and durability of aluminum depend on its thickness gauge. In this guide, we will explain which gauge is most beneficial according to your needs.
1. Aluminum 1.2mm Gauge (For Light Use)
This is the most commonly used gauge, especially for those on a budget. It is generally used for light applications.
Where to use
Small home windows, bathroom doors, and areas where the glass weight is low.
Benefit
It is affordable and sufficient for general household use.
2. Aluminum 1.4mm Gauge (Balanced Strength)
This gauge is ideal for those who want more strength than 1.2mm.
Where to use
Medium-sized home windows and doors that are used frequently.
Benefit
It is less flexible compared to 1.2mm and provides a stronger grip for screws.
3. Aluminum 1.6mm Gauge (Standard Choice)
If you want the best balance between strength and cost, 1.6mm is the standard choice. It is commonly used for frequently used doors.
Where to use
Large room windows and standard sliding doors.
Benefit
It can handle more weight than 1.4mm and maintains its shape for a longer time.
4. Aluminum 2mm Gauge (For Large & Heavy Applications)
For large sliding doors and double glazed units, choosing a 2mm gauge is essential.
Where to use
Terrace doors, main hall windows, and double glazed units.
Benefit
It easily supports heavy glass and provides excellent resistance against strong wind pressure.
5. Aluminum 3mm Gauge (Commercial & Heavy Duty)
This is a very strong and heavy section used for specific commercial needs, especially with 12mm glass.
Where to use
Large shopfront glass, commercial office partitions, and areas where security is a top priority.
Benefit
It is a long-term investment, does not bend easily, and offers maximum safety.
Summary: What Should You Choose?
Bathroom small windows: 1.2mm gauge
Standard room windows: 1.4mm or 1.6mm gauge
Large sliding doors double glass: 2mm or above.
