Ask your average Joan to name as many types of wood as possible and she'll probably come up with a decent list. The metals of the world? No problem. But glass? Well, there's glass and then there's&#; glass&#;?
Despite its ubiquity, most people couldn't tell you the difference between toughened, annealed, and laminated glass. We're not criticising &#; life is quite complicated enough without knowing the ins and outs of glass manufacturing.
But whether you're a homeowner or a business owner, there may come a day when you're looking to install a gorgeous bit of laminated glass &#; an elegant skylight, perhaps, or a flash walk-on glass floor. When that day comes, you'll need to know your way around a glass catalogue.
At ToughGlaze, we make a point of keeping our customers in the loop. We're not the kind of company that murmurs "Leave it to us" and then leaves you in the dark. We want you to understand your options so you can make an informed decision.
In that spirit, we've put together this quick, no-nonsense guide to a side of glass manufacturing that can sometimes be shrouded in mystery: the world of laminated glass interlayers.
Scrolling through your options, you'll probably come across a tangle of acronyms: PVB, EVA and SGP. What do they mean?
To answer that question, we first need to understand what laminated glass is &#; and what it does.
What is laminated glass?
Sometimes, glass needs to be especially robust. Common sense will tell you that you're not going to make a glass ceiling out of the same material you'd use for a cafetière or tumbler.
Laminated glass is made out of two or more layers of glass with an interlayer. This is like the filling in a glass sandwich &#; one tough enough to break your teeth. The interlayer stops the glass from breaking into large pieces. Instead, it cracks in a spider web pattern &#; the kind you might have seen on a broken windscreen.
What is laminated glass?
Laminated glass is a safety glass that is made up of two layers of glass or more layers of glass that are bonded together with an interlayer. The interlayer can be polyvinyl butyral (PVB interlayer), ethylene-vinyl acetate (EVA), or SGP interlayer (SentryGlas by Kuraray). It is called VSG in some EU countries.
What are the similarities and differences between the laminated and tempered glass?

What kind of laminated safety glass can we get?
Annealed laminated glass, heat-strengthened/semi-tempered VSG, fully tempered and laminated glass.
Benefits of laminated glass
-Durability: it has a much shorter lifespan than non-laminated.
-Safety: it is often six to eight times stronger than regular glass and can withstand extreme force.
-Sound barrier: The noise of the outside world cannot come through the glass, so the household sound is not disturbed.
-Keep out UV light: laminated glass windows can filter over 99.9% of UV rays into the room.
-Security: it is virtually impossible to break into, which makes it a perfect option for those who want to maintain a certain level of privacy.
Disadvantages of laminated glass
-Weight: it is heavier than standard glass, so it needs to be used in areas where it can support the extra weight.
-Cost: it is more expensive than standard glass, so it may not be a practical option for all applications.
-Fragility: Laminated glass is still fragile and can break if not handled properly.
-Worse Feasibility: it has to be pre cut to the ideal size since it is not easy after lamination.
Is laminated glass good to use?
YES.
It is a great option for many different applications.
It is durable, tough, and long-lasting, and can reduce the effects of winds, earthquakes, and impacts from outside.
It is also aesthetically pleasing and can be personalized to suit your needs.
It provides sound-proof function, safety & security.
It is the best glass to protect your furniture from UV rays.
Which is better, laminated glass or toughened glass?
Both laminated and tempered glass have their own advantages and disadvantages.
VSG is a great sound barrier, can be used to keep out UV light, and is more difficult to break into than tempered glass. However, it is more fragile than tempered glass and is also heavier.
Tempered glass is less expensive and is less likely to shatter on impact, but it does not offer as much noise insulation or privacy protection.
VSG is more expensive to replace if it gets damaged, but it is stronger and more difficult to break into. Tempered glass is less expensive, but it doesn&#;t offer the same level of security as VSG.
What is the cost of laminated glass?
The minimum cost of 3mm clear glass+0.38mm+3mm clear glass is US $10~$12/sqm.
The cost varies big with different compositions and thicknesses.
Can laminated glass be cut?
Yes, annealed laminated glass can be cut to size. The glass needs to be cut while it is still in the lamination film, and special tools and techniques are required.
Semi tempered glass laminated glass and fully tempered laminated safety glass cannot be cut again.
Does laminated glass noise-proof?
Yes, it is an effective noise-proofing material.
However, it cannot be used as a noise-proof glass. It can be only regarded as noise-proof glass with acoustic PVB interlayers.
What type of glass is suitable for laminated glass windows, canopy, and roofs?
Some of the most common types that can be used for these applications include:
-Heat-strengthened/semi-tempered laminated glass
-Fully toughened laminated glass
-SentryGlas with SGP interlayer from Kuraray

Does laminated glass reduce heat and glare?
It does reduce heat and glare, but it also blocks ultraviolet light. This makes it a good choice for applications where you need protection from the sun&#;s harmful rays.
Is laminated glass as good as double glazing?
VSG is not as good as double glazing, but it is a good alternative for applications where double glazing is not possible or not desired.
Double glazing creates an insulating barrier that helps to keep heat in or out of a building, depending on the season. VSG can also be effective at reducing noise and glare, but it doesn&#;t offer the same level of insulation as double glazing.
What is Sentry laminated glass? And where SentryGlas can be used?
SentryGlas is a combination of safety glasses and DuPont ionoplast interlayer.
As the only structural safety glass in the industry, it is widely used for hurricane windows, doors, balustrades, stair treads, canopies, giant curtain walling, edge exposed places, etc.
There are 57 certified SentryGlas process manufacturers in China mainland with Kuraray registered trademark. Kindly contact us through or for the processor list.
What are the main properties of laminated glass?
-Durability
-Safety
-Security
-Design flexibility
-UV control
-Solar control
How strong is laminated glass?
Laminated glass is very strong and can resist a lot of pressure.
Broken glass will stick to the interlayers even after breakage, which helps to reduce the risk of injury.
It can withstand a lot of pressure and is less likely to break than annealed glass.
Is laminated glass energy efficient?
Laminated glass is often seen as an energy-efficient option for windows and doors.
This is because it can help to reduce the amount of heat that is lost in colder climates.
It also helps to reduce the amount of noise that comes in from outside, making it a good option for windows in noisy areas.
Is laminated glass impact resistant?
Laminated glass is not designed to withstand impact resistance. There is impact resistant function with thicker PVB layers or SentryGlas SGP interlayer.
Laminated glass is less likely to break than regular glass, making it a good option for windows and doors.
Is laminated glass more secure than tempered glass?
Laminated glass is more secure than tempered glass.
With outside impact, the tempered glass breaks into particles and falls down. However, laminated glass will stick to the interlayers even after broken.
Does laminated glass need a kitemark?
It depends on the client. We propose to print a kitemark on laminated glass.
The kitemark serves as an indicator for the customer.
It acts as a traceable remark to the manufacturer if the glass is broken.
What is semi-tempered laminated glass?
It is a type of safety glass that consists of two or more pieces of semi-tempered glass/heat-strengthened glass and is combined with an interlayer.
Is semi-tempered laminated better than tempered and laminated glass?
Semi-tempered laminated glass is thought to be a better option than tempered laminated glass. It is stronger and more resistant to breaking.
What are the safety glass standards of laminated glass and what certificates do you have?
Different continents have different safety glass standards:
USA Standard: ASTM C , SGCC certificate
EN standard: EN , CE certificate
Australia & New Zealand: AS , AS & NZS certificate
Chinese standard: GB, CCC certificate
Where to buy laminated safety glass?
For small quantities, you can just order from local processors.
For big quantities, you can place an order to Elite Safety Glass at a very good wholesale price.
