Bulletproof

Bullet-resistant window glass is a special type of safety glass designed to withstand direct bullet impacts. They are made up of several layers of glass and polyvinyl butyrate (PVB) film or other polymers that provide additional protection. Their thickness and number of layers are tailored to the specific threat level and bullet resistance classification, which is defined by international standards such as UL (Underwriters Laboratories) or EN (European Standards) standards.

Construction of bulletproof glass

Layers of Glass: Several layers of glass are used in bulletproof glass, which can be of various types, including tempered, reinforced or laminated.
Energy-absorbing films: Films of PVB or other materials are placed between layers of glass to absorb the energy of the impact, helping to stop the projectile.
Multi-layer construction: The overall structure forms a multi-layered structure that can effectively absorb and dissipate the impact energy of the bullet, preventing it from penetrating the glass.

Features and applications of bulletproof glass

Protection against firearms attacks: These glasses are designed to withstand shots from a variety of weapons, from pistols to rifles.
Use in high-risk areas: They are used in government buildings, embassies, military and police vehicles, banks, and private homes in regions where there is a higher risk of armed attacks.
Preserving transparency and aesthetics: Despite their thickness and layered structure, bulletproof glass maintains transparency, allowing visibility and not disrupting the aesthetics of the building.
Noise reduction: Due to their weight and construction, bulletproof glass can also effectively insulate against outside noise.
UV protection: Like other laminated glass, they can be equipped with a UV filter to protect the interior from fading.
