When it comes to choosing the right glass for your home or building, two popular options are Low E glass and tempered glass. Both have unique features and benefits, but which one is better for your needs?
In this article, we’ll compare Low E glass and tempered glass in terms of performance, cost, and applications to help you make an informed decision.
What is Low E Glass and Tempered Glass?
Define Low E Glass
Low Emissivity (Low E) glass is a type of energy-efficient glass designed to reduce heat transfer. It has a thin, transparent coating that reflects infrared light, keeping heat inside during winter and outside during summer. There are two types of Low E glass: hard-coat and soft-coat. Hard-coat Low E glass is more durable, while soft-coat offers better insulation.
Tempered Glass Meaning
Tempered glass is a safety glass that is four to five times stronger than regular glass. It is made by heating the glass to a high temperature and then cooling it quickly. This process makes the glass more resistant to impacts. If it breaks, it shatters into small, blunt pieces instead of sharp shards, reducing the risk of injury.
Difference Between Low E and Tempered Glass
Tempered vs Low E Glass Energy Efficiency
- Low E Glass: The main advantage of Low E glass is its energy efficiency. It reduces heat transfer, which helps maintain a comfortable indoor temperature. This can lower your heating and cooling costs. The U-value (how well it insulates) and SHGC (Solar Heat Gain Coefficient) are key metrics. Low E glass has a low U-value and SHGC, making it ideal for energy-saving homes.
- Tempered Glass: Tempered glass does not have the same energy-efficient properties as Low E glass. It is more about safety and strength than insulation.
Low E Glass vs Tempered Glass Soundproofing
- Low E Glass: While Low E glass is not specifically designed for soundproofing, its insulating properties can help reduce noise to some extent.
- Tempered Glass: Tempered glass is slightly better at reducing noise due to its thickness and strength, but it is not a soundproofing solution.
Tempered vs Low E Glass Safety
- Low E Glass: Low E glass is not safety glass. If it breaks, it can form sharp pieces, which can be dangerous.
- Tempered Glass: Tempered glass is much safer. It is designed to break into small, harmless pieces, making it ideal for areas where safety is a concern, such as shower doors or glass railings.
Tempered Glass vs Low E Light Transmission
- Low E Glass: Low E glass allows natural light to pass through while blocking harmful UV rays. This protects your furniture and flooring from fading.
- Tempered Glass: Tempered glass also allows light to pass through, but it does not have UV protection unless it is combined with a Low E coating.
Low E Glass vs Tempered Applications
- Low E Glass: Best for energy-efficient windows, skylights, and doors. It is ideal for homes in extreme climates where temperature control is important.
- Tempered Glass: Commonly used in areas requiring safety, such as shower enclosures, glass doors, and car windows.
Low E Glass Vs Tempered Cost
- Low E Glass: More expensive than regular glass due to its energy-saving properties. However, it can save you money on energy bills in the long run.
- Tempered Glass: Slightly cheaper than Low E glass but more expensive than standard glass. Its cost is justified by its safety features.
Low E vs Tempered Glass Pros and Cons
| Feature | Low E Glass | Tempered Glass |
|---|---|---|
| Energy Efficiency | Excellent | Poor |
| Safety | Not safety glass | High safety (shatters into small pieces) |
| UV Protection | Blocks UV rays | No UV protection (unless combined with Low E coating) |
| Cost | Higher initial cost | Moderate cost |
| Durability | Standard durability | Highly durable |
| Applications | Windows, skylights, energy-efficient doors | Shower doors, car windows, glass railings |
Both Low E glass and tempered glass have their own strengths and weaknesses. Low E glass is ideal for energy efficiency and UV protection, while tempered glass excels in safety and durability. By understanding the pros and cons of each, you can choose the right glass for your specific needs. If you need both energy savings and safety, consider combining the two for the best results.
How to Choose Between Tempered vs Low E Glass?
- Choose Low E Glass if:
- You want to save on energy bills.
- You live in a hot or cold climate.
- You want to protect your furniture from UV rays.
- Choose Tempered Glass if:
- Safety is your top priority.
- You need glass for high-impact areas like bathrooms or balconies.
- You want durable glass that can withstand heavy use.
If you need both energy efficiency and safety, you can combine Low E Tempered Glass. Many modern windows use this combination for maximum benefits.
Conclusion
Both Low E glass and tempered glass have their own advantages. Low E glass is ideal for energy efficiency and UV protection, while tempered glass is best for safety and durability. Your choice depends on your specific needs and budget. If you want the best of both worlds, consider using a combination of Low E and tempered glass.
By understanding the differences between Low E glass and tempered glass, you can make a smarter choice for your home or building. Whether you prioritize energy savings, safety, or both, there’s a glass solution that’s right for you.
FAQs
Does Low E glass reduce natural light?
No, Low E glass allows natural light to pass through while blocking heat and UV rays. It does not significantly reduce the amount of light entering your home.
Can tempered glass be cut or drilled?
No, tempered glass cannot be cut or drilled after it has been tempered. Any alterations must be made before the tempering process.
Is Low E glass more expensive than tempered glass?
Yes, Low E glass is generally more expensive due to its energy-saving properties. However, it can save you money on energy bills over time.
Can tempered low e glass be used together?
Yes, combining Low E glass with tempered glass is a great option. This provides both energy efficiency and safety.
Which glass is better for soundproofing?
Neither Low E glass nor tempered glass is specifically designed for soundproofing. However, tempered glass is slightly better at reducing noise due to its thickness.
