What’s hurricane-proof Laminated glass?
Single tempered glass cannot be used as hurricane-proof glass, even though tempered glass strength is 3-5 times higher than normal float
glass, but as it can be broken into fragments after broken, the fragment will cause further injury to people.
Hurricane Resistant Glass Application:
Curtain walls, glass skylights, railings,windows&doors, also used as structural glass applications, for example, glass stairs, floors, glass bridges.
The Hurricane-proof Glass Must Meet Several Requirements:
1)High strength and Difficult to break.
2)Glass keeps the integrity and not be penetrated after breaking.
Hurricane Proof Glass Can be Classified Into 3 types:

1. PVB Laminated Glass
The PVB laminated glass here is tempered laminated glass with polyvinyl butyral.
The tempered glass itself has high strength and even one piece is broken in the hurricane, the interlayer can keep the glass’s overall integrity, meanwhile work as a barrier to prevent the inner piece glass been impacted.
The PVB interlayer also prevents the glass been penetrated.
PVB laminated glass will collapse once the 2 piece glass is all broken, the PVB interlayer is soft and has low shearing modulus, cannot hold the broken glass.
2. SGP Laminated Glass
SGP laminated glass has high strength.
SGP laminated glass bearing capability is 2 times that of PVB laminated glass, but the bending deflection of SGP laminated is only 1/4 of PVB laminated glass under the same thickness and load condition.
The tearing strength of SGP interlayer is 5 times higher than PVB film, even if the glass breaks, the SGP can also stick the glass and form a temporary structure while keeping small bending deformation, it can withstand a certain amount of load and whole piece laminated glass won’t fall or deform.
Laminated glass processed with SGP interlayer film can effectively block damage to buildings when a hurricane strikes. it can greatly improve the impact resistance of safety glass. Performance, anti-theft, anti-riot performance, and anti-disaster performance.
3. Polycarbonate Laminated Glass
The PC board is not easy to break, and its compressive strength is 250 times that of float glass, and it is 50-100 times stronger than that of tempered laminated glass.
Even if it is hit with a hammer, there is no risk of breakage.
Polycarbonate laminated glass is usually used as anti-intrusion glass, and bulletproof glass, so it has the highest strength against hurricanes, but its price is extremely high.
