Features of Low E Glass
Low-E
ALow E glass is coated with a metal oxide film that effectively reflects infrared radiation, thereby reducing heat conduction. This means that indoor heating can be maintained in winter, while the burden of air conditioning can be reduced in summer.
High Light Transmittance
This glass can effectively filter ultraviolet rays while maintaining a high visible light transmittance, ensuring sufficient indoor light and helping to save energy.
Anti-UV Performance
ALow E glass can effectively block most ultraviolet rays and reduce the fading of indoor furniture, carpets and artworks.
Energy Saving And Environmental Protection
Due to its excellent thermal insulation performance, buildings using ALow E glass can significantly reduce energy consumption, thereby reducing the impact on the environment.
Anti-fog Performance
Some types of Low E glass also have good anti-fog performance, making it difficult for windows to condense water vapor in environments with large temperature differences.
Application of Low E Glass
Residential Windows
Low-E glass is frequently used in windows for homes to reduce heat loss during winter and minimize heat gain during summer. This contributes to lower energy bills and improved indoor comfort.
Commercial Buildings
Many commercial buildings utilize Low-E glass in their facades and windows to enhance energy efficiency and comply with building regulations concerning energy performance.
Skylights
Low-E glass is ideal for skylights, as it permits natural light while reducing heat buildup, making indoor spaces more comfortable.
Curtain Walls
In modern architectural designs, Low-E glass is often used in curtain wall systems. This allows for dramatic design elements and extensive glazing while still providing energy efficiency.
Doors
Exterior doors, especially those with large glass panels, benefit from Low-E coatings to offer improved thermal performance.
Glass Railings and Balustrades
Low-E glass can be used in railings and balustrades to maintain clear views while helping to control heat loss and gain.
Greenhouses
Low-E glass can be beneficial in greenhouses where managing temperature is essential for plant growth while still allowing adequate light penetration.
Automotive Applications
Low-E coatings are also applied to vehicle windows to enhance thermal performance, helping to keep the interior cooler while allowing visibility.
Single Coated Low-E Glass
This features a single layer of low-emissivity coating applied to one side of the glass. It offers moderate thermal insulation and is more cost-effective.
Double Coated Low-E Glass
This has a double layer of low-emissivity coating and typically provides better thermal performance compared to single-coated options. It is more effective in reducing heat loss.
Soft Coat Low-E Glass
This type is produced by depositing the low-E coating onto the glass surface while it is still hot, resulting in a very thin and highly reflective layer. It offers superior thermal insulation and is often used in residential applications.
Hard Coat Low-E Glass
In contrast to soft coat, hard coat Low-E glass is created through a pyrolytic process where the coating is baked onto the glass while it’s produced. It is more durable and can withstand harsher conditions, making it suitable for commercial applications.
Passive Low-E Glass
Designed for maximum solar gain and passive heating, this type reflects some solar energy while allowing most visible light to enter. It's often used in climates where heating is a priority.
Solar Control Low-E Glass
This type is designed to minimize solar heat gain. It reflects a higher percentage of solar radiation, making it ideal for hot climates where cooling loads are a concern.
Triple Glazed Low-E Glass
This involves three layers of glass with two spaces filled with argon or krypton gas for added insulation. It can come with one or more Low-E coatings, providing excellent thermal performance.
Low-E Glass with Tints
Some Low-E glass options are also tinted to reduce glare and further minimize solar heat gain, improving energy efficiency and comfort in bright conditions.
Production Process of Low E Glass
Raw Material Preparation
1. Silica Sand: The primary raw material, along with other materials like soda ash, limestone, and various additives, is selected and prepared.
2. Batch Mixing: These raw materials are mixed in specific proportions to form a glass batch.
Melting
1. Furnace: The glass batch is melted in a furnace at high temperatures (around 1,400 to 1,600 degrees Celsius).
2. Glass Formation: As the raw materials melt, they form molten glass that will later be processed into sheets.
Glass Forming
Float Glass Process: The molten glass is poured onto a bath of molten tin, allowing it to spread and form flat sheets of uniform thickness and smooth surface. This is known as the float glass process, which is the most common method for producing flat glass.
Annealing
The glass sheets are slowly cooled in an annealing lehr to relieve internal stresses. This step ensures the glass has the strength and durability required for further processing.
Coating Application
● Low E Coating: Once the glass sheets have cooled and are not under stress, a thin, low-emissivity coating is applied to one side of the glass. This coating typically consists of one or more layers of metallic oxides (such as silver, tin oxide, or indium oxide) which are applied using techniques such as:
1. Sputtering: A physical vapor deposition process where a target material is bombarded with ions, causing atoms to dislodge and deposit onto the glass surface.
2. Chemical Vapor Deposition (CVD): A process that involves chemical reactions that produce a thin film on the glass surface.
Inspection and Cutting
After coating, the glass is inspected for quality, checking for defects or inconsistencies in the coating.The coated sheets are then cut into desired sizes and shapes according to specifications.
Further Treatment (if required)
1. Edge Processing: Depending on end-use, the edges may be polished or treated to improve aesthetics and safety.
2. Tempering or Laminating: For applications requiring additional strength or safety, the glass may undergo tempering (heating and rapid cooling) or laminating (sandwiching with a layer of PVB or other interlayer).
Products Packaging and Shipping of Low E Glass
Inspection and Preparation
1. Inspect the Glass: Before packaging, inspect the Low E glass for any damage. Clean the glass surface from dust and debris, as residues can scratch the coating.
2. Temperature Considerations: Ensure that the glass is at room temperature before packing to minimize thermal stress.
Packaging Materials
1. Edge Padding: Use foam edge protectors or corner protectors to cushion the edges of the glass.
2. Protective Film: If the glass has a protective film, keep it on until installation to prevent scratches.
3. Blankets or Bubble Wrap: Wrap the glass sheet in padded blankets or high-quality bubble wrap. Ensure that the wrap covers it completely to provide comprehensive cushioning.
4. Box or Crate: Use a sturdy cardboard box or a wooden crate that is designed for glass transportation. The box should be slightly larger than the glass to provide room for padding.
Cushioning and Layering
1. Layering: If shipping multiple sheets of glass, separate each sheet with layers of corrugated cardboard or foam sheets to prevent them from touching each other. Make sure that there’s enough cushion to absorb shocks.
2. Block and Brace: If using a wooden crate, block and brace the glass sheets within the crate to prevent movement during transportation.
Sealing and Labeling
1. Sealing the Box: Use high-quality packing tape to seal the box securely. If using a wooden crate, ensure that all fasteners are tight.
2. Labeling: Clearly label the package as “Fragile” and “Glass” on all sides. Indicate "This Side Up" to ensure handlers know how to orient the package.
Shipping Considerations
1. Choose the Right Carrier: Select a carrier experienced in handling fragile items. Discuss any special requirements they may have for glass shipments.
2. Insurance: Consider purchasing insurance for the shipment to cover losses in case of damage during transit.
3. Tracking: Use a shipping method that includes tracking to monitor the shipment status.
Handling Upon Arrival
1. Inspect Upon Delivery: When the package arrives, inspect it for damage before signing for it. Report any damage immediately to the carrier.
2. Proper Storage: Store the glass sheets in a vertical position in a dry, safe location until they are ready for installation, avoiding any pressure on the edges.
