Tempered and Tempered Laminated Glass
Glass is a beautiful and versatile material that adds light, style, and functionality to our homes and buildings. However, when it comes to safety and security, standard glass can be a liability. Thankfully, advancements in glass technology have given us superior options – tempered glass and laminated glass.
This blog delves into these safety glasses, with a particular focus on their ultimate combination: tempered laminated glass.
What is Laminated Glass?
Laminated glass, also known as bonded glass, is a type of safety glass created by bonding two or more layers of glass together with a transparent plastic interlayer, typically polyvinyl butyral (PVB). This interlayer plays a crucial role in the safety and performance of laminated glass.
Here’s a breakdown of the lamination process:
Cleaning and Preparation
The glass panes are meticulously cleaned to remove any dust or debris that could create imperfections.
Interlayer Application
The PVB interlayer, available in various thicknesses, is carefully placed between the prepped glass pieces.
Heating and Pressing
The entire assembly is then subjected to heat and pressure in an autoclave. This activates the PVB, causing it to bond firmly to the glass panes.
Types of Laminated Glass
Laminated glass offers a surprising amount of versatility based on the type of interlayer used and the number of glass plies:
Standard PVB Laminated Glass
This is the most common type, offering excellent protection against impact and shattering.
Stimsonite Laminate
This incorporates a retroreflective layer within the interlayer, enhancing nighttime visibility for applications like building signage.
Hurricane Laminate
Engineered with a thicker and stronger PVB interlayer, hurricane laminate provides superior protection against high winds and flying debris.
Security Laminate
This type incorporates a thicker PVB interlayer with a tear-resistant mesh, making it highly resistant to forced entry attempts.
DuPont SentryGlas Laminate
This innovative laminate utilizes a special ionoplast interlayer, offering exceptional clarity, strength, and improved edge stability.
Multilayer Laminated Glass
By using more than two glass pliers with interlayers, even higher levels of security and ballistic protection can be achieved.
What is Tempered Glass?
Tempered glass, also known as toughened glass, is another type of safety glass created by a thermal tempering process. Here’s what happens:
Cutting and Shaping
The raw glass is cut and shaped to the desired specifications.
Heating and Rapid Cooling
The glass is heated to a specific temperature (around 620°C) and then rapidly cooled with forced air. This process creates compressive stress on the outer surfaces and tensile stress in the core.
Increased Strength and Safety
The tempering process makes the glass several times stronger than standard glass. If it breaks, it shatters into small, blunt fragments instead of large, sharp shards, significantly reducing the risk of injury.
What is Tempered Laminated Glass?
Tempered laminated glass is the ultimate combination of safety and performance. As the name suggests, it combines the benefits of both tempering and lamination. This powerhouse material is created by first tempering the individual glass plies and then bonding them together with a PVB interlayer.
This combination offers unparalleled safety and performance advantages:
Exceptional Strength
Tempered laminated glass is significantly stronger than either tempered or laminated glass alone. It can withstand significant impact without breaking or shattering.
Enhanced Safety
Even if the tempered laminated glass is impacted with enough force to break, the PVB interlayer holds the fragments together, preventing them from falling out and causing injuries. This is a crucial advantage in areas with high foot traffic or where children might be present.
Improved Security
The strength and tear-resistant properties of tempered laminated glass make it highly resistant to break-ins and vandalism. This makes it an ideal choice for storefronts, banks, and other applications where security is a top priority.
Sound Insulation
The PVB interlayer helps dampen sound waves, making tempered laminated glass an excellent choice for applications requiring noise reduction. This can be beneficial for homes located near busy roads, offices seeking a quieter environment, or music studios needing to contain sound.
UV Protection
Depending on the interlayer type, tempered laminated glass can filter out a significant portion of ultraviolet rays. This can help protect furnishings, artwork, and valuables from fading caused by sun exposure.
Tempered Glass vs. Tempered Laminated Glass: Choosing the Right Option
While both tempered glass and tempered laminated glass are safety glasses, they cater to different needs. Here’s a breakdown to help you choose the right option for your project:
Tempered Glass
- Pros: More affordable, excellent impact resistance, shatters into small, blunt fragments.
- Cons: It offers less security against break-ins, and fragments may still fall out upon breakage.
Tempered Laminated Glass
- Pros: Superior strength and security, fragments remain bonded even if broken, improved sound insulation and UV protection.
- Cons: More expensive than tempered glass.
Applications
Here are some typical applications for each type of glass:
- Tempered Glass: Shower doors, glass partitions, appliance glass (e.g., oven doors), tabletops, and furniture.
- Tempered Laminated Glass: Storefront windows, bullet-resistant glass, skylights, architectural features, glass railings, aquariums, and high-security areas like banks and jewelry stores.
Here’s a quick decision-making guide:
- Choose tempered glass if your primary concern is affordability and the application doesn’t require high levels of security, impact resistance, or noise reduction. Examples include shower doors, interior partitions, or tabletops.
- Choose tempered laminated glass if security, safety, noise reduction, or UV protection are essential for your application. This is ideal for storefronts, banks, skylights, or locations with high foot traffic.
