5 Things to Know Before Buying 4mm laminated glass price

What is laminated glass?

Northglass contains other products and information you need, so please check it out.

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?

Similarities:

• they are both of standard safety glass.
• they both can be used for safety applications, preventing forced entry, natural disasters, and human impact.
• they both have high strength than annealed glass.

Differences:

• tempered glass is a single piece, while VSG is two layers or multiple layers.
• laminate glass's vinyl interlayer filters UV rays, toughened glasses are more impact-resistant.
• tempered glass is made through a tempering furnace, in the tempering process, the glass will be heated first and then cooled rapidly. VSG is made of two pieces of glass or multi-layers of glass, combined by a special plastic layer.
• when broken, tempered glass shatters into obtuse particles, while laminated glass fragments will be bigger and similar to annealed 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.

1. Glass thickness: 8mm+8mm is two to three times expensive than 4mm+4mm.
2. Different PVB layer: there is a big price gap between 0.38mm & 1.52mm interlayer.
3. Heat-treated: annealed glass, heat-strengthened and tempered glass varies big.
4. Other factors: glass yielding rates, shaped glass, glass with holes, etc.

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

Where are the laminated glass products used for?

-laminated tempered glass windows

-safety glass doors

-glass floors

-glass facades

-glass canopy

-glass sandwich doors

-glass stair treads

-glass windshield

-glass skylights

-tempered glass laminated mirror

-other architectural glass applications

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.

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.

This intact breakage illustrates how tempered glass forms tiny, countless pieces. However, most tempered glass shatters to the ground upon impact.

Note that even though there was a powerful impact, this tempered glass has remained structurally intact.

Tempered vs. Laminated: How To Choose The Right One For Your Job

So for strength and breakage-resistance, temper glasses often is the first consideration. For flexibility, UV-resistance, security and sound considerations, laminated glass is often the product of choice. Both are considered safety glazing materials and can be obtained in a variety of thicknesses and colors or tints. Both are easy to clean and maintain when installed properly.

Keep in mind that tempered glass cannot be cut. Once glass has undergone the tempering process, piercing the surface will cause the glass to explode. If using tempered glass for a project, be sure that all sizing is completed before the glass is tempered. In contrast, laminated glass can typically be cut and sized at any time without issue, which could be a benefit for some projects.

Typically, laminated glass products are a slightly higher price than tempered products of the same type and thickness. The optical clarity for both laminated and tempered glass are excellent in either product will provide many years of satisfactory service in your door or window.

Transcription of Breaking Tempered Glass Video

Daniel: So we're here to break some more glass! What do we have today?

Dustin: So this is an insulated unit. This is essentially what most windows are made up of. It's two pieces of glass with a spacer in between that creates dead air space, and that's what insulates it.

Daniel: So this basically what you would find in a residential home for people's windows?

Dustin: Absolutely. Also in a commercial setting; very similiar process. So this pieces of glass is actually a safety glass. It's tempered. Both sides are actually tempered. So it takes a really good shot. It's rigid. But it's point sensitive, which is why we've given you this fun tool to break it with.
So when it breaks- and it doesn't break like a regular piece of plate glass in big pieces- it breaks into small pieces so if it were to fall on you, obviously it doesn't hurt you as bad. So why don't you show us what happens when you break tempered glass.

So what's really cool about tempered, for me, is that you can typically tell where it breaks from. So it actually spiderwebs from the location. Now, this will continue to crack. It will continue to break.

Daniel: Yeah, we can actually hear it right now.

Dustin: You can hear it, right. And then eventually it will fall out. So tempered glass breaks into these small pieces. Will these cut you? For sure. This can definitely still cut you. It's still glass. But the reality of it is, this doesn't cut you as bad, or can cut you as bad, as what the larger pieces do.

So when tempered glass breaks, it breaks into small pieces. We noticed earlier when you hit it, that you kind of bounced off a time or two, right? You didn't necessarily put much swing into it. Well, tempered is point sensitive because there's energy trapped inside, but it's also edge sensitive. So what I want to let you do, is I want you to hit the edge of it. But instead of using a point, I'm going to let you wrench it around and see what you can make happen.

Daniel: Alright, let's see what happens.

Dustin: Give her a shot!

Daniel: So you can see it's just kind of like a little chip right there.

Dustin: For sure. Now here's an interesting piece of this- a lot of times you find or hear of glass breaking spontaneously, right? Spontaneous glass breakage. Something like this can actually cause this piece of glass to break in six months, or in a year. And if that got chipped at some point during the process of making it, and it still got installed, that can explain some crazy day where this piece of glass blows up.

Daniel: And that's actually really common in the automotive world with sunroofs especially. Those are a lot of times made of tempered glass. People say that they'll just be driving down the road and all of a sudden the sunroof explodes.

Dustin: Yea, it's just one of those things that's really hard to explain and if you try to put a story behind it, there's really no telling. But that right there can cause an issue for sure down the road.

Daniel: Alright, so let's take another stab at it'It's tougher than it looks!

Dustin: Alright, there you go. So with the right amount of force and hitting it at the right angle definitely causes the issue of having it come apart. The other beauty of this is, we didn't have the back side to hold it in, so you saw that one actually came apart. Similiar story with the sunroof exploding. So there you have it man, that's kind of how the whole tempering process works.

Daniel: This is laminated glass.

Dustin: This is laminated. So laminated is a type of safety glass. There's essentially three safety glasses. Tempered, laminated, and then an acrylic or plexiglass, which is kind of a plastic base.
So what we have here is two pieces of glass that are laminated together with a film- an adhesive film. And essentially this is annealed, or plate glass, on both sides.

Daniel: And so where would you find this?

Dustin: So interesting fact: Almost everybody looks through this nearly every day because this is what your windshield is made out of. But also we use this in a lot of areas for storefront. If you see a gas station that has been broken into, sometimes this is what we put in to deter thieves from getting in. It's a lot harder to get into.
We also use it in bullet-resistant glass. They laminate multiple pieces together. You'll find it sometimes in residential. And in those cases it's typically in a hurricane (prone) area where you have to have some blast type of glass.

Daniel: Alright well let's take a shot at trying to break this and kind of demonstrate what that laminated interlayer does for the glass to keep it together.

Dustin: For sure!

Daniel: Wow!

Dustin: So that's a great first shot. You can see where it broke from. Just like most glass, you can always see where it spiderwebs from and where it goes. That actually looks a lot like what your windshield looks like when a big rock hits it, right? Maybe not quite that extreme. But you can also tell that it's still intact. This piece of glass' integrity is there.

Daniel: It's solid.

Dustin: Correct. I mean, it's not going anywhere. It also is really not likely to cut you. All of these runs that you see'

Daniel: It's pretty much totally smooth.

Dustin: It's smooth! It's held together by the interlayer. So why don't you give it a couple more hits in the same spot so we can show just what it takes to literally get through this thing.

So what you can see is the interlayer. You can see the plastic interior of the laminate piece. It actually holds together really really well. So what you've done is broken the glass away but the interlayer is still there.

Daniel: Yea, so that'll deter theft, like you said, in a storefront. If you're in your automobile and this is your windshield then it's going to keep your windshield together while you're going down the road, or god forbid, if you hit the windshield.

Dustin: So a cool piece of this is, all of this damage that you've done and this thing is still together. It hasn't come apart. It won't hurt you essentially. It could. But for the most part, this is what makes this a safety glass.

Daniel: Yea, and that's extremely important for residents like in Florida where they have a lot of hurricanes; there's a lot of wind damage; storm damage. So if this was a window on your home, I think you'd be pretty safe during a hurricane.

Dustin: For sure. You hear about windows blowing out all the time. This would be one of those windows that doesn't do it.
