Custom Safety Glass.
For building Code compliance, “Safety Glazing” requires either tempered or laminated glass tested to ANSI Z97.1-2015 or CPSC 16 CRF 1201.
Moag Glass offers precision fabrication of two types of laminate interlayers to best meet your architectural needs.
SentryGlas (SGP)
S.G., SentryGlas, is the “O.G.” of Laminated Glass products.
Originally developed by Dupont for the hurricane glazing market, this interlayer is used where high-performance glass is required.
SentryGlas is made using ionoplast polymer technology, chemically different from EVA and PVB interlayers. Up to 100 times stiffer than other interlayers, the post-glass breakage performance makes SGP the ideal glass product for high-risk, high-profile buildings.
- SECURITY/ ANTI-INTRUSION GLASS
- STRUCTURAL GLAZING
- BOMB-BLAST RESISTANT GLASS
Ethylene-vinyl acetate (EVA)
E.V.A, Ethylene-vinyl acetate, with its hydrophobic nature and edge stability, is the latest safety glass innovation.
E.V.A: Ethylene-vinyl acetate
EVA Interlayer was designed to encapsulate.
With less glass haze and more light transmission than Sentryglas, EVA is a comparable choice in most applications. A revolutionary thermoplastic copolymer resin that is both non-sticky and inert to water moisture it offers edge stability and the most design opportunities.
EVA Glass Inter-layer vs. PVB Inter-layer
An evolution of clear glass lamination from PVB to EVA. Developed in 1927, PVB is still found in architectural drawings. Learn more below about how laminated glass is assessed and why EVA interlayer is now considered a better design choice.
In a head-to-head laminated glass comparison, EVA is the superior product.
EVA surpasses visual standards while withstanding the stresses of temperature, moisture, radiation, and mechanical stress.
Laminated Glass Transparency “Haze”
Better transparency, glass clarity, or “optics” is mainly defined as less haze. Haze is the amount of light that goes through the glass but that is transmitted in a fuzzy way. Glass laminated with EVA has better optics with a haze value of .05% when compared to a PVB haze value of .13%
Light Transmittance
Light transmittance is the % of visible light that goes through glass and a second way to measure its transparency. EVA Clear Inter-layer has higher light transmittance; 91% compared to PVB’s 89% light transmittance.
UV Protection
EVA offers high UV protection, blocking 99% of UV rays with proper thickness application.
Adhesion
With 3x’s higher adhesion than PVB, EVA is the ideal product for glass that will undergo mechanical stress and fatigue such as doors, stairs, or exterior facades.
Cross-linking Technology
One of the most significant differences between thermoset EVA and other thermoplastics and PVB is the cross-linking technology. During the curing phase of lamination, EVA cross-links. This is a non-reversible process through which the EVA laminated glass becomes:
- HYDROPHOBIC / WATERPROOF
- HIGHLY ADHERED
- UV RESISTANT
Acoustic Insulation
Another term for laminated glass is “acoustic glass”. EVA laminate provides higher soundproofing than standard PVB laminate. In residential and commercial applications, it’s worth considering glass to provide a transparent solution for noise reduction and sound privacy.
Safety under stress.
When exposed to moisture and then broken, EVA laminated glass remains intact.
TCV breakage test photos, shown above, display how when broken, EVA Laminated glass stays cohesive in contrast to PVB glass.
EVA Laminated Glass Color Options
EVA Lami Glass is underutilized in art-glass applications.
With EVA lamination, added interlayer options include transparent color films, fabrics, and metallic inserts. Turn non-traditional materials like fabric or mesh into a pane of safety glass. Permanently transform materials by encapsulating them between glass sheets then use this EVA laminated, composite glass in any application where a traditional, safety-glass product would apply.
EVALAM Colored Glass Laminate for Indoor Laminated Glass Applications
Evalam Color was developed with two objectives in mind:
- Durability
- Color Uniformity
Mix Evalam Outdoor Colors with layers of Evalam transparent colors to vary translucency and opacity.
DECOLAYER Colored Film Lamination
Benefits of color film laminated within EVA inter-layer include:
- Maximum clarity, durability, and stability over time
- UV-ray protection
- Moisture resistance is suitable for exterior, open-edge applications
- Acoustic isolation
- Superior impact-resistance

Product Compatibility
Other advantages of EVA interlayer include its compatibility. Utilize decorative inserts like P.E.T, electronic inserts like PDLC, Polycarbonate, or photovoltaic applications for unique and innovative glass design.
Ceramic Frit Coating
Compatible with any laminated glass and used in both interior and exterior glass applications, this digital ceramic ink application is a permanent glass fabrication providing long-lasting, vivid colors that are fused into the glass for outstanding durability, even in extreme conditions.
Maximum clarity, durability, and stability over time
Ceramic inks offer unmatched resistance to scratching, acid, UV, and weather, ensuring
long-lasting vivid colors.
During the tempering process, the inks are fused directly into the glass so that the printed
image lasts as long as the glass. In all other digital printing, the ink is printed on top of the
tempered glass and does not fuse into the glass.
Ceramic inks are compliant with the demanding industry standards for quality and
durability.
