When it comes to glass and mirror products, one of the primary concerns people have is safety and security. People have it at the back of their minds that glass is fragile and, as a result, not safe for use, especially in homes with children or places with high mobility and traffic.
While this concern is valid, it is untrue that glass is not safe. Several glass types and products possess senile strength and durability. One such product is laminated glass.
WHAT IS LAMINATED GLASS?
It is a safety glass type that is made up of two or more glass panels. The glass panels are held together by layer between the glass panes. The interlayer is usually a polyvinyl butyral sheet, thermoplastic urethane sheet, or ethylene-vinyl acetate sheet.
The goal of the interlayer between the glass panels is to prevent the glass shards from flying about and causing injuries if the laminated glass panel breaks. They hold all the pieces together and prevent them from falling.
So, instead of large glass shards scattered all around that could pose harmful threats, you have a spider web pattern that shows that the glass has shattered.
How Is Laminated Glass Made?
Laminated glass is manufactured by bonding together two or more glass panels using polyvinyl butyral (PVB) as a layer between the glass panels. The resulting layers are bonded together by making use of chemical bonds and mechanical bonds.
Afterward, heat and apply it to the bonded glass unit to get rid of air bubbles that may be trapped in the layers. The result is a tight seal. The group becomes a single durable and robust glass panel that can resist impact and strength.
The glass panel, in the case of glass breakage, does not break into multiple pieces as a result. Instead, the PVB layers between the laminate hold the sharp glass shards together. This is what results in the “web-like” patterns when breakage occurs.
The production of laminated glass consists of five main processes. They are:
- Step 1: This is the first and preparatory step. The glass to be used is cut into the desired designs, shapes, and sizes based on the specifications of the clients.
- Step 2: The cut glass panels are taken to washing machines with feeding devices as well as roller tables. This step minimizes larger gaps between the glass panes.
- Step 3: The glass panes are cleaned and dried thoroughly with automated machines.
- Step 4: Once the panes are cleaned and dried, they are moved to a room with conditioned humidity and temperature. The conditioned room is clean and free of dust.
- Step 5: The cut and design are perfectly aligned alongside the PVB films used. The resulting group is placed on a nip roller. The group is heated and simultaneously compressed to eliminate excess air that may be trapped in-between the glass layers.
- Step 6: The final process involves the transfer of the laminate glass to the auto-clave cart, where supervised heat and pressure cycles are applied on the laminated glass to improve clarity.
HOW IS IT DIFFERENT FROM TEMPERED GLASS?
Any glass type that is produced to reduce breakage or make glass secured during breakage is a safety glass. As a result, laminated glass and tempered glass are both safety glass types. Although they are both safety glass, there are differences between the two glass types.
● Difference in Strength
The strength difference between a laminated glass and tempered glass is of considerable distinction. On average, tempered glass has a tensile strength of 5,000 pounds per square foot while a laminated glass can have up to 10,000 pounds per square foot.
While this may look like the tempered glass is stronger, it is worthy to note that a laminated glass can also be produced using tempered glass. In this case, the result is a far more reliable and durable laminated glass compared to tempered glass.
● Difference in Cost
A laminated glass possesses numerous other features and benefits that make it a costly safety glass. It supports a strong resistance to shock and is excellent at resisting break-in attempts.
The PVB interlayer resists striking that’s continuous by weapons like hammers, wood cutting blades, amongst others. Laminated glass also can resist bullets for a specific period. Hence, the laminated glass is more than just a safety glass. Instead, it is a glass type with high-level security benefits.
As a result of the other benefits, a laminated glass costs so much more than tempered glass, but considering the benefits, laminated glass is a worthy investment that is worth the spend.
● Difference in Uses
Tempered glass and laminated glass are both safety glass types but vary in their uses and applications. As mentioned above, laminated glass are of high-level security and offer security benefits.
A laminated glass is commonly used as follows:
- Safety glass
- Insulating glass
- Security glass
- Control/soundproof glass
- Noise reduction glass
- Solar control glass
- UV protection glass
- Storm resistance or hurricane glass
- Balustrades or making rails
- Blast mitigation glass
- For making skylights
Tempered glass, on the other hand, has limited applications and cannot be used solely as a security component but can be used as a component of bulletproof glass, amongst others.
WHICH GLASS IS BETTER?
Having taken a long look at what laminated glass is, how it’s made, uses, and applications amongst other things, it is highly recommended to choose a laminated glass instead of a tempered glass for so many reasons.
Asides being a safety glass just like tempered glass, a laminated glass is also a security glass. This is great for both residential and commercial uses. As a result, it makes it a better glass type to opt for when compared to tempered glass.
Although a laminated glass costs so much more than tempered glass, the expense should be considered as a valuable investment that offers numerous returns through the many benefits it possesses.
