Vanceva® Brings Color to Traditional Benefits of Laminated Glass
Vanceva® color interlayers offer certain high-performance safety characteristics, useful in demanding applications such as vertical, sloped and overhead glazing. The tough plastic interlayer resists penetration from accidental impact and, unlike ordinary glass, won't shatter into dangerous fragments if broken. Vanceva color PVB interlayer is sold at a minimum of 15 gauge (0.38 mm, 0.015 in). Laminated glazing made with Vanceva interlayer, when used in the proper thickness can meet the federally mandates safety glass requirements of CPSC and is also able to meet the various requirements outlined in ANSI and ASTM standards related to laminated glass. Below are some common applications where Vanceva color interlayer is commonly used.
Vertical Safety Glazing:
Typical applications requiring safety glazing include entrance doors, storm doors, patio-type sliding doors, shower and bath enclosures, sidelights and fixed glazed panels. These federal requirements for safety glazing are outlined in CPSC CFR 16 Part 1201 and the voluntary standard ANSI Z97.1 provides test and specification information for safety glazing used in areas not addressed by the CPSC document.
Laminated glass made with Vanceva PVB color interlayer breaks safely. While the glass may crack under impact, it typically remains integral. Glass splinters and sharp fragments tend to adhere to the plastic interlayer. This is in contrast to annealed glass, which fractures easily into long, sharp-edged shards, or tempered glass which breaks into pieces that may reduce cutting or piercing injuries, but still has the predominance to vacate the frame once broken.
Vanceva color PVB interlayer can effectively help protect people and property without compromising design aesthetics. The resilient interlayer resists forced entry even from repeated blows from hand-held implements such as hammers, crowbars and bricks. Laminated glass made with Vanceva® color interlayers cannot be cut from one side, denying burglars the use of glass cutters for quiet entry. For specialized high-security applications, laminated glass of varying configurations can provide ballistic and blast resistance.
Laminated architectural glass made with Vanceva color interlayer offers greater protection for people and property than other glass products. Standard industry constructions are proven to provide protection when subjected to attack by burglary, forced entry, bombs and even ballistics. Security glazing refers to the almost limitless family of products constructed from laminated glass which is designed to withstand the complex dynamic impact loads resulting from intentional assault. Threats to facilities which can be countered with specific security glazing constructions include:
- Burglary and Forced Entry
- Ballistic Attacks (in special applications)
- Bomb Blast (in special applications)
- Burglary-Resistant Glazing
Burglaries frequently are not directed at a specific facility but toward targets of easy opportunity and low perceived risk. The most critical step in a burglary is entry. Standard two-ply laminated architectural glass provides a significant improvement over monolithic glass and standard insulating glass products in resistance to forced entry, and is capable of passing Underwriters Laboratory Test UL 972 and ASTM F 1233 Class 1 body passage.
With the appropriate configurations, laminated security glazing made with Vanceva color interlayers can successfully resist penetration of bullets and reduce the amount of impact-induced spall (fragmentation from the protected side of the glazing) as a result of ballistic attacks. Traditionally, the ability of security glazing to resist ballistic attack has been measured using the UL 752 test
Bomb Blast-Resistant Glazing:
Laminated security glazing using Vanceva color interlayer, in specifically designed window, doors and skylight systems, can provide impact protection that may substantially reduce injury from direct and indirect blast shock wave effects (over-pressures) and can significantly reduce the amount flying or falling glass in bomb attacks.
Glass can allow the transmittance of sound as well as light into a building's interior. Laminated glass with Vanceva color interlayer can effectively reduce the transmittance of noise between spaces and from outside to inside better than conventional glazing systems. The dampening characteristics of laminated glass can minimize the interference in classrooms, meetings, and general conversation caused by disruptive noise - from traffic and jet aircraft to office machinery and industrial equipment.
Laminated glass is highly effective in reducing unwanted sound transmission. The acoustical performance of laminated glass is the result of the damping characteristics of the interlayer. Laminated architectural glass effectively reduces the coincidence dip in the 1,000 to 3,000 Hertz range common to glass products. Coincidence occurs when the wavelength of sound in air is equal to the bending wavelength of sound in a panel. The panel becomes highly transparent to the sound in this frequency range.
Reduced Solar Gain:
Laminate systems made with Vanceva® color interlayer can help control solar heat gain and reduce cooling loads in commercial buildings. The interlayer absorbs energy in the ultraviolet (UV), visible and infrared wavelength spectrums and dissipates most of the absorbed energy to the outside. For increased solar or thermal performance, the Vanceva interlayer can be fabricated into insulating glass units or can be combined with low–e or reflective glass. Similar to the way sun block protects your skin, Vanceva interlayers screen out and virtually eliminate harmful and damaging UV radiation. Vanceva filters out UV light and helps protect and preserve interior furnishings and fabrics, drapes and wall coverings, photographs and artwork from fading and deterioration.
