Gutmann PVB - UV Protection

In the world of glass technology, the development of laminated glass has revolutionized the way we approach safety, security, and even protection from harmful UV light radiation.

Laminated glass is made by sandwiching a polyvinyl butyral (PVB) interlayer between two or more layers of glass. This construction not only enhances strength and durability but also offers exceptional UV radiation blocking capabilities.

One notable player in this field is Gutmann PVB, a leading manufacturer of Polyvinyl Butyral (PVB)

In this post, we will delve into the fascinating properties of laminated glass and how Gutmann PVB laminated glass effectively blocks 99% of harmful UV light radiation.

Understanding Harmful UV Light Radiation:

Ultraviolet (UV) light is an invisible form of radiation emitted by the sun. Although UV rays are essential for vitamin D synthesis and have certain therapeutic benefits, prolonged exposure can pose significant health risks. The three primary types of UV rays are UVA, UVB, and UVC. UVA rays can penetrate deeper into the skin, contributing to premature aging and an increased risk of skin cancer. UVB rays are responsible for sunburns and are also associated with skin cancer. UVC rays are generally absorbed by the Earth's atmosphere and do not reach us in significant amounts.

The Protective Power of Laminated Glass:

Laminated glass acts as a protective shield against harmful UV light radiation due to the unique properties of its PVB interlayer. The PVB interlayer is a high-performance polymer that acts as a filter, selectively blocking a large portion of UV rays from passing through the glass. When compared to other types of glass, such as annealed or tempered glass, laminated glass provides superior UV protection.

Gutmann PVB Interlayers

Gutmann PVB has perfected the art of producing laminated glass with exceptional UV radiation blocking capabilities. Gutmann PVB laminated glass is specifically designed to block up to 99% of harmful UV light radiation, offering optimal protection to individuals within the vicinity of the glass.

Benefits of Gutmann PVB Laminated Glass:

UV Protection: With its remarkable UV radiation blocking capacity, Gutmann PVB laminated glass ensures a safe indoor environment, reducing the risk of skin damage, premature aging, and skin cancer.

Enhanced Safety: In addition to UV protection, laminated glass provides superior safety benefits. When shattered, the PVB interlayer holds the glass together, preventing dangerous shards from scattering, thereby reducing the risk of injury.

Sound Insulation: Laminated glass, including Gutmann PVB laminated glass, exhibits excellent sound insulation properties. It helps reduce external noise pollution, creating a more serene and peaceful indoor environment.

Security: The interlayer in laminated glass also enhances security. It makes the glass more difficult to break, deterring potential intruders and providing an extra layer of protection against forced entry.

Applications of Gutmann PVB Laminated Glass:

Gutmann PVB laminated glass finds application in a wide range of settings, including:

Residential buildings: Windows, doors, skylights Commercial buildings: Facades, storefronts, partitions Automobile industry: Windshields, sunroofs Museums and galleries: Display cases, art protection Sports facilities: Stadiums, arenas


Gutmann PVB laminated glass stands as a testament to the remarkable advancements in glass technology. Its ability to block 99% of harmful UV light radiation, combined with the numerous safety, security, and sound insulation.
