Laminated Glass

High strength and performance with beauty and versatility, these are the characteristics of the laminated safety glass manufactured by GlassecViracon.

A laminated unit is composed of two or more glass lites joined by a PVB interlayer that prevents the glass from falling out of the opening in the event of breakage. This feature reduces the risk of bodily injury and property damage, in addition to maintaining a closed façade.

Laminated glazing is ideal for applications requiring different levels of acoustic performance and safety. Additionally, it offers greater protection against UV rays and broad aesthetic possibilities with the selection of colors and varying PVB opacity.

laminated glass fabricated by GlassecViracon meets the requirements of the Brazilian standards NBR 11706 and NBR 14697.

Configurations Available


Simple laminated glass consists of two glass lites intercalated with PVB and is widely used in facades and balustrades.

Multi Laminated Glass

Multi-laminatedglass is manufactured with two or more glass lites held together by one or more interlayers, which provides the product with a high level of safety. Also known as anti-vandalism glass, it is suited for environments that require greater protection, such as banks, storefronts and guardhouses.


GlassecViracon utilizes an objective nomenclature to identify each of its products, describing them according to five features: name of product, product type, aspect, thickness, and product code. The code GA designates regular standard products, while the code GL is used for customized products. Thus, you can easily find and select the glazing product that you want to specificate, together with its respective performance details.

You can specify architectural glass according to criteria such as the glass aesthetic or the glass performance. On this website when you search for glass, you must select the information in five fields :

  • CONFIGURATION: insulating, laminated or monolithic.
  • GLASS TYPE: clear (colorless), tinted (colored) or solar control.
  • SILK-SCREEN: Yes or No.
  • AESTHETIC: clear (colorless), green, dark green, grey, bronze, blue, extra clear.
  • PERFORMANCE: LT (light transmittance) and the SF (solar factor).

ISO 9001

GlassecViracon confers a high quality standard to all of its processes and products. In 2002 we received our first ISO 9001 certification, and went through recertification audits in 2009 and 2014. The ISO 9001 standard covers all our operations – planning, purchasing, manufacturing, transportation, sales, customer service and administrative services –to ensure the highest level of quality toour services and solutions.


We are the only company in the Brazilian market that has a Laboratoryof Quality Control where testing is carried out to ensure the uniformity of colors andshades of our glazing products. Every batch of raw-material undergoesspectrophotometry tests, besides other specific tests according to the product’s characteristics.
