What’s the Difference Between SGP and PVB Interlayers?

When it comes to glass panels, finding the ideal design for your needs can sometimes seem tough, but this shouldn’t have to stop you from finding the optimal materials. With this thought in mind, today, we’ve outlined some of the key things you need to know about the difference between SGB and PVB to help you find the optimal type of glass panel for your home or commercial property.

Both SGP and PVB interlayers offer numerous great benefits, but it’s important to consider them to ascertain which one might be right for your needs. Indeed, there are numerous different features that can influence whether SGP or PVB is right for your needs, and our experts have summarized some key things you should know to help.

What is SGP?

First of all, we need to consider what SGP is. SGP is one of the newer materials on the market for interlayers, offering a highly popular and versatile option for filling your glass panels. SGP is otherwise known as Ionoplast or SentryGlas, and as a more novel option, it’s incredibly popular for the high-quality properties it can provide.

What is PVB?

If you’re looking for a more traditional glass interlayer, PVB might be ideal. PVB, or polyvinyl butryl, is a highly popular and readily available glass material traditionally used for soundproofing glass and creating laminated glass panes.

Generally speaking, it’s still generally considered the industry norm for laminated glass panels, meaning that PVB interlayers are far more likely to be present in your property’s glass.

Are They The Same?

PVB and SGP do roughly similar jobs, but they’re not the same in terms of their overall properties. SGP generally tends to be stronger, tougher, and more durable overall than regular PVB, making it vital for high-strength applications. In fact, estimates suggest that SGP can be even hundreds of times stronger than PVB, making this highly important to keep in mind.

But, with that being said, it’s worth keeping in mind here that SGP may be less effective for reducing noise transfer and UV light than PVB.

Which is Right for Your Project?

While SGP is generally substantially stronger than regular PVB interlayers, this unique material is often far more expensive to purchase – unaffordably so for many people. In line with this, if you have been trying to find the right material for your glass panels, considering your budget carefully is very important.

In addition, looking at whether you need UV protection and reduced noise transfer is also highly important to keep in mind. Remember: not every property or project will be the same, and nor will their requirements be.

Final Thoughts
