Product Parameters
Introduction
Coating Type:
Hard-Coat: Applied during the glass manufacturing process at high temperatures, offering durability and scratch resistance. Ideal for environments with frequent handling.
Soft-Coat: Deposited via sputtering technology in a vacuum, providing superior energy efficiency but requiring extra protection during installation.
Visible Light Transmittance (VLT)
Ranges from 10% to 80%. Higher VLT allows more natural light to enter, while lower VLT enhances privacy and solar control.
Solar Heat Gain Coefficient (SHGC)
Typically between 0.20 - 0.80. A lower SHGC blocks more solar heat, reducing cooling loads in summer.
U-Value
As low as 0.8 - 1.8 W/(m²·K) for double-pane Low-E glass, indicating excellent thermal insulation compared to standard glass (U-value 5.8 W/(m²·K)).
Thickness
Available in single-pane (3 - 12mm), double-pane (16 - 40mm), and triple-pane configurations. Thicker units offer enhanced insulation.
Size Range
Standard sizes up to 300cm x 600cm. Custom sizes can be tailored to specific architectural requirements.
Color Options
Clear, tinted (blue, green, gray), or reflective finishes, providing both aesthetic flexibility and light control.
Frequently Asked Questions
● What is the main difference between Hard-Coat and Soft-Coat Low-E glass?
Hard-coat is durable and scratch-resistant, applied during manufacturing, while soft-coat offers superior energy efficiency but is more delicate and typically used in insulated glass units.
● How does the U-Value impact my building's energy consumption?
A lower U-Value means better thermal insulation. Low-E glass with a U-Value of 0.8-1.8 significantly reduces heat loss compared to standard glass, lowering heating costs.
● What SHGC value should I choose for a hot climate?
In hot climates, a lower SHGC (Solar Heat Gain Coefficient) is preferable as it blocks more solar heat from entering the building, reducing the load on air conditioning.
● Can I get Low-E glass in custom sizes?
Yes, while standard sizes go up to 300cm x 600cm, custom sizes can be tailored to meet specific architectural and design requirements.
● Does Low-E glass reduce natural light inside the room?
It depends on the VLT (Visible Light Transmittance). With options ranging up to 80%, you can choose glass that allows high levels of natural light while still providing thermal protection.
