Understanding Window and Door Glass: Key Facts
1. Insulated Glass (Double Glazing)
Insulated glass has two or more layers with dry gas in between. This design blocks noise and heat transfer. For example, Aluminium Sliding Doors often use this glass to keep rooms quiet and energy-efficient. Thicker gas layers (like 12mm) work better for insulation .
Insulated glass is common in Aluminium Windows and Commercial And Household Glass projects. It prevents moisture and dust, making it ideal for Double Glazing Doors and Windows in humid or cold areas.
2. Tempered Glass
Tempered glass is heat-treated for strength. It can handle heavy impacts. If broken, it shatters into small, safe pieces. For example, Aluminium Doors in busy areas often use tempered glass to reduce injury risks.
This glass suits large Aluminium Windows or Double Glazing Doors. It resists wind pressure and accidental damage, especially in commercial buildings.
3. Glass Thickness
Glass thickness depends on window size and use. Larger windows need thicker glass. For example:
Small Aluminium Windows (under 1.5㎡): 4-5mm glass.
Large Aluminium Sliding Doors (over 6㎡): 8-12mm glass.
Thicker glass improves safety. For Commercial And Household Glass projects, 6-8mm tempered glass is widely used.
4. Aluminium Spacer Bars
Aluminium spacer bars separate glass layers in insulated units. High-quality bars have smooth surfaces and tight seals. They stop moisture from entering the gas layer.
For example, Double Glazing Doors and Windows with good spacers last longer in coastal areas. These bars also help Aluminium Casement Windows stay airtight in extreme weather.
Why It Matters
Choosing the right glass improves durability and energy savings. For global buyers, these details help source reliable Aluminium Windows and Double Glazing Doors that meet project standards.
