Laminated glass interlayers offer a selection of color and opacity not achievable with other glass products such as coatings, glass substrates, silk-screen or spandrel glass. This is especially true with bright, vivid colors as well as opaque or translucent / frosted aesthetic requirements.
Viracon’s architectural laminated glass products with a minimum .030″ pvb interlayer comply with ANSI Z97.1-1984 and CPSC 16 CFR 1201, which are the industry safety standards for glazing materials.
Laminated glass provides 99% UV light blockage at the wavelength range of ~300 – 380 nanometers
Viracon offers a vast selection of interlayer options to meet your specific requirements.
Polyvinyl butyral (pvb) – standard architectural interlayer available in three thicknesses:
Saflex® SilentGlass Acoustic – a three layer system designed to decouple and disseminate sound waves for superior sound damping performance. Interlayer available in .030″ thickness.
SentryGlas® – an ionoplast interlayer bonded directly between two layers of glass for superior protection. The rigid interlayer minimizes deflection. Available interlayer thicknesses:
Level E – SentryGlas® – a specialized interlayer combination that is used for Level E hurricane applications.
StormGuard® – an enhanced polyvinyl butyral (pvb) interlayer which provides excellent adhesion to glass and optimum performance for large missile hurricane-resistant applications. StormGuard has less deflection and better tear resistance than standard pvb interlayers. It is also available in combination with Vanceva® Color interlayers. Interlayer available in .100″ thickness.
Level E – StormGuard® – a specialized interlayer combination that is used for Level E hurricane applications.
Saflex® Storm – a pvb / pet film / pvb composite laminated between two panes of glass. The composition provides the impact resistance of pvb and the tear resistance of a polyethylene terephthalate (pet) film. Interlayer available in .077″ thickness.
Vanceva® Color – interlayer system made up of base colors and a range of white interlayers that can be combined to achieve varying layers of translucency and color.
How Vanceva Works
Each Vanceva base interlayer is designated by a number or letter.
A single color can be selected or the base interlayers can be stacked to provide the specific color and opacity desired. Up to four interlayers* can be stacked between two plies of glass within a laminated glass unit.
Each Vanceva Color combination is given a four digit code. The specific layers and order of the layers determines the four digit code. This code can then be used in your laminated glass specification.
If the desired color is achieved with less than four base interlayers clear pvb is typically added to achieve .060” thickness and is represented with a zero.
*Note: Vanceva Color base interlayers are limited to three interlayers when used in combination with a coating. Due to coating and Vanceva Color base interlayer properties, a clear pvb interlayer must be placed between the coating and interlayer
