Laminated Safety Glass

Xpert BM - 800x400 Clear

When safety, durability, and long-term performance matter, 18.28mm Laminated SGP Glass (8+2.28+8mm) stands out as a premium solution for modern architecture. Engineered to withstand extreme weather, high wind loads, and forced impact, this advanced Laminated SGP Glass is widely trusted for hurricane impact windows, impact glass windows, and high-end architectural glazing projects worldwide.

Designed for strength without compromising clarity, SGP interlayer glass delivers exceptional rigidity, superior edge stability, and outstanding resistance to breakage—making it the ideal choice for coastal regions and high-risk environments.

What is 18.28mm Laminated SGP Glass?

18.28mm Laminated SGP Glass is a high-performance safety glass composed of two 8mm glass panels bonded together with a 2.28mm SGP (SentryGlas® Plus) interlayer. Unlike traditional PVB laminates, SGP interlayer glass is significantly stiffer and stronger, providing enhanced structural integrity even after breakage.

This structure allows the glass to remain firmly in place when subjected to heavy impact, making it a preferred material for hurricane impact windows, impact doors, and large-span glazing systems. Compared to standard laminated glass, Laminated SGP Glass offers up to five times the tear strength and 100 times the rigidity.

FAQs for Order 18.28 mm SG Interlayer Glass

1- Can I get a free sample from Xpert BM?

For a first-time cooperation, we are happy to provide free samples for simple products such as clear tempered glass and clear laminated glass to support our initial collaboration. However, we are unable to cover the shipping costs. We hope both sides can share some of the expenses from a partnership perspective. If this order and project move forward and we work together in the future, these costs can be fully deducted from our formal cooperation.

2-Can I visit the factory?

In general, this is not a problem. Please contact us using the form below, and our team will get in touch with you.

Additionally, please note that our partner suppliers are located in various regions across China, and the glass and aluminum factories in particular are often situated in relatively remote areas. Visiting them in person can be costly overall. If you would like to save time and effort, we can arrange to visit them on your behalf under your company’s name.

3-Do you offer door-to-door service?

Yes, we do offer door-to-door service. We can arrange it according to your location, and the exact cost and lead time will be confirmed based on the destination and shipping method you prefer.

4-What is the shipping cost? Will it be expensive?

The shipping cost depends on the destination, product type, and shipping method (air, sea, or express).

For large or heavy items like glass, window, door, curtain wall, sea freight is usually the most cost-effective option. While international shipping can be a significant part of the total cost, we always work to find the most economical and efficient solution for our customers and can provide a detailed quotation for your reference.

5- What guarantees do my orders come with?

For tempered glass and standard laminated glass, we generally offer a 5-year warranty. For higher-performance glass, such as insulated glass, Low-E glass, and coated glass, we typically provide a 10-year warranty.

Please note: As glass is inherently fragile, there is always a risk of breakage during transportation. Even for tempered glass, despite our use of high-quality raw glass from XYG, CSG, and PPG, and processing with advanced tempering furnaces from NorthGlass and LandGlass, there is still an approximate 0.2% risk of spontaneous breakage. If any damage occurs, we will do our best to assist you in minimizing the loss.

6- I just want to buy for my private house or project, do you have suggestion?

Of course. Xpert BM was founded with the mission of helping all our clients solve their challenges. Our primary customers are individuals small and medium contractors, and we are always happy to listen to their ideas. Our professional team will carefully consider their needs and provide the most suitable advice and recommendations.

7-How does SGP glass price compare to standard laminated glass?

While SGP glass price is higher than PVB laminated glass, it delivers superior performance, longer lifespan, and reduced maintenance costs—making it a cost-effective investment.

8-Is Laminated SGP Glass suitable for high-rise buildings?

Yes. Due to its structural strength and post-breakage performance, it is widely used in high-rise facades and curtain wall systems.

9-Is 18.28mm Laminated SGP Glass compatible with existing window and door framing systems?

In most cases, yes. However, because SGP glass is stiffer and heavier than standard laminated glass, frame systems should be designed or verified to support the additional load. We recommend confirming structural compatibility during the design phase to ensure optimal performance of impact glass windows.

10-Can 18.28mm Laminated SGP Glass be used for oversized or floor-to-ceiling panels?

Yes. One of the main advantages of Laminated SGP Glass is its ability to support larger panel sizes with minimal deflection. This makes it ideal for floor-to-ceiling impact glass windows, panoramic facades, and modern architectural designs that require both strength and transparency.
