Tempered and laminated glass are both considered safety-glazing options, but they are manufactured differently and behave differently when broken. The best choice depends on where the glass will be used, how much impact resistance is needed, and what should happen if the glass is damaged.
Below, this residential glass replacement contractor in Oak Brook, Illinois is going to explain how tempered and laminated glass compare and when each type may be appropriate.
What Is Tempered Glass?
Tempered glass is heat-treated to increase its strength compared with standard annealed glass.
If it breaks, it is designed to fracture into many small, relatively blunt pieces rather than large sharp shards. A qualified residential glass replacement contractor in Oak Brook, Illinois can determine whether tempered safety glass is appropriate or required for the location being repaired.
What Is Laminated Glass?
Laminated glass is made by bonding two or more layers of glass around a durable plastic interlayer.
If the glass breaks, the interlayer helps hold the fragments together instead of allowing the entire pane to fall apart. This gives laminated glass a different breakage pattern from tempered glass and can help the opening remain covered after impact.
How Do Tempered and Laminated Glass Break Differently?
The biggest difference is what happens after breakage.
Tempered glass is designed to break into small pieces that separate from one another. Laminated glass can crack extensively while the interlayer continues holding many of the fragments in place.
For homeowners in the Oak Brook, Illinois area, the preferred behavior may depend on where the glass is located and what safety or security concerns are most important.
Is Tempered Glass Stronger Than Laminated Glass?
The comparison is not as simple as saying one is always stronger.
Tempered glass is treated to improve its resistance to impact and thermal stress. Laminated glass gets important performance characteristics from the bonded layers and interlayer, particularly its ability to remain together when broken.
The glass thickness, construction, size, and intended application all affect performance.
Does Laminated Glass Provide Additional Security?
It can.
Because broken laminated glass tends to remain attached to the interlayer, it can be more difficult to create an immediate open space through the glazing after impact. Different laminated products are available for different performance needs.
An experienced residential glass replacement contractor in Oak Brook, Illinois can help you compare glass options based on the location and purpose of the panel rather than choosing solely by appearance.
Can Laminated Glass Help Reduce Noise?
Yes, certain laminated glass configurations can help reduce sound transmission.
The interlayer can dampen some vibration as sound passes through the glass. The amount of sound reduction depends on the glass thickness, interlayer, overall construction, and surrounding conditions.
Does Laminated Glass Help Block UV Rays?
Laminated glass can block a substantial amount of ultraviolet radiation because of its interlayer.
That can help reduce one contributor to fading in flooring, fabrics, artwork, and furnishings. It cannot prevent all fading, since visible light, heat, and other factors can also play a role.
Where Is Tempered Glass Commonly Used in a Home?
Tempered glass is often used in locations where safety glazing is required or desirable.
Applications can include certain glass panels near walking areas, railings, furniture, shelving, and other locations where breakage could create a safety concern. Building-code requirements can vary based on the location and dimensions of the glass.
At Glass & Mirror America, we work with homeowners to match replacement glass to the application, dimensions, safety requirements, and appearance of the existing space.
How Do I Know Which Type of Glass I Need?
The location of the glass is the starting point.
Safety requirements, size, exposure to impact, security concerns, sound control, and the original glass construction can all affect the recommendation. Existing glass markings may also provide information about whether a panel is tempered or certified as safety glazing.
