As a supplier of aluminium sliding doors, I often encounter customers who are unsure about how to choose the right glass for their doors. The glass used in aluminium sliding doors plays a crucial role in not only the aesthetic appeal but also the functionality, energy efficiency, and safety of the doors. In this blog post, I will share some key factors to consider when selecting glass for aluminium sliding doors.
1. Type of Glass
There are several types of glass available for aluminium sliding doors, each with its own unique properties and benefits.
Float Glass
Float glass is the most common type of glass used in residential and commercial applications. It is made by floating molten glass on a bed of molten tin, which results in a smooth and flat surface. Float glass is relatively inexpensive and provides good clarity, but it is also the least energy - efficient and offers limited protection against breakage.
Tempered Glass
Tempered glass is a type of safety glass that is heat - treated to increase its strength. When tempered glass breaks, it shatters into small, blunt pieces rather than sharp shards, reducing the risk of injury. Tempered glass is often required for sliding doors in areas where safety is a concern, such as near swimming pools or in high - traffic areas. It is also more resistant to thermal stress and impact than float glass.
Laminated Glass
Laminated glass consists of two or more layers of glass bonded together with a layer of polyvinyl butyral (PVB) interlayer. This interlayer holds the glass together when it breaks, preventing it from shattering and providing an additional layer of security. Laminated glass is also effective at reducing noise transmission and blocking UV rays, making it a good choice for areas where privacy and comfort are important.
Insulated Glass Units (IGUs)
Insulated glass units, also known as double - or triple - glazed glass, consist of two or three panes of glass separated by a spacer and filled with an insulating gas, such as argon or krypton. IGUs are designed to improve energy efficiency by reducing heat transfer through the glass. They can also help to reduce noise transmission and condensation on the interior surface of the glass.
2. Energy Efficiency
Energy efficiency is an important consideration when choosing glass for aluminium sliding doors, especially in regions with extreme climates. The energy performance of glass is measured by several factors, including the U - value, Solar Heat Gain Coefficient (SHGC), and Visible Transmittance (VT).
U - Value
The U - value measures the rate of heat transfer through the glass. A lower U - value indicates better insulation and less heat loss in the winter and less heat gain in the summer. Insulated glass units with low - emissivity (Low - E) coatings typically have lower U - values than single - pane glass.
Solar Heat Gain Coefficient (SHGC)
The SHGC measures the amount of solar radiation that passes through the glass and is absorbed by the interior of the building. A lower SHGC means less solar heat gain, which can help to reduce cooling costs in the summer. Low - E coatings can also be used to reduce the SHGC of glass.
Visible Transmittance (VT)
The VT measures the amount of visible light that passes through the glass. A higher VT means more natural light can enter the building, which can reduce the need for artificial lighting. However, a high VT may also result in more solar heat gain, so it is important to balance the VT with the SHGC.
3. Safety and Security
Safety and security are paramount when it comes to sliding doors. As mentioned earlier, tempered and laminated glass are both excellent choices for enhancing safety. In addition to the type of glass, you may also want to consider additional security features, such as multi - point locking systems and impact - resistant glass.
Multi - Point Locking Systems
Multi - point locking systems provide a higher level of security by engaging multiple locking points along the edge of the door. This makes it more difficult for intruders to force the door open.
Impact - Resistant Glass
Impact - resistant glass is designed to withstand high - impact forces, such as those caused by severe weather or attempted break - ins. It is often used in areas prone to hurricanes or in commercial buildings where security is a major concern.
4. Aesthetics
The glass you choose for your aluminium sliding doors can have a significant impact on the overall aesthetic of your space. Consider the following aesthetic factors when making your decision:
Clear vs. Tinted Glass
Clear glass provides maximum visibility and allows natural light to flood the interior of the building. Tinted glass, on the other hand, can reduce glare and solar heat gain while adding a touch of privacy. Tinted glass comes in a variety of colors, including bronze, gray, and green.
Frosted or Textured Glass
Frosted or textured glass can be used to add privacy without sacrificing natural light. These types of glass have a decorative finish that diffuses light, making it difficult to see through the glass while still allowing light to pass through.
Frameless vs. Framed Glass
Frameless glass doors provide a sleek and modern look, while framed glass doors offer more structural support and can be customized with different frame colors and finishes. The choice between frameless and framed glass depends on your personal style and the architectural design of your building.
5. Cost
Cost is always a factor when making any purchasing decision. The cost of glass for aluminium sliding doors can vary depending on the type of glass, size of the doors, and additional features. While tempered and laminated glass are generally more expensive than float glass, they offer better safety and performance. Insulated glass units with Low - E coatings are also more expensive but can result in significant energy savings over time.
