The JEB 3SEAL™ insulating glass spacer system is designed for the toughest commercial glazing demands. The spacer system is made from structural thermoset silicone with integral 3A desiccant and features a triple-seal design consisting of a pre-applied acrylic adhesive for spacer-to-glass bonding, a hot-applied captive polyisobutylene primary seal, and a two-part structural silicone secondary seal.

With its no-metal design, JEB 3SEAL has shock-absorbing properties that counteract glazing stresses caused by wind, snow, driving rain, fluctuating temperatures, and barometric pressure. In addition, JEB 3SEAL has minimal thermal conductivity, providing higher glass edge surface temperature, and a multi-layer vapor barrier to enhance condensation resistance.

J.E. Berkowitz Laminated Glass is produced by sandwiching one or more layers of PVB or structural layer materials between multiple lites (two or more) of glass and applying a combination of heat and pressure to permanently “fuse” the layers together creating Fusion™ Laminated Glass, and SentryGlas®, all using Kuraray™ technology.

Types of laminated glass:

• Laminated PVB
• Laminated Impact Glass
• Laminated Sound Control Glass
• SentryGlas® Laminated Glass

Fabrication of Insulating Glass Units is accomplished on three automatic vertical insulating lines with the distinct advantages of:

• On-line edge deletion to ensure proper sealant adhesion
• On-line argon gas filling
• Grey and Black primary and secondary sealants
• Warm edge technology airspacers
• Standard clear and black airspacers

Heat-strengthened glass is flat glass that has been heat treated to have a surface compression between 3,500 and 7,500 psi (24 to 52 MPa) which is twice the surface compression of annealed glass and meets the requirements of ASTM C 1048. It is intended for general glazing, where additional strength is desired to withstand wind loads and thermal stresses. However, heat-strengthened glass is not a safety glazing material.

Fully tempered glass is flat glass that has been heat-treated to have a minimum surface compression of 10,000 psi (69MPa) resulting in resistance to impact of approximately four times that of annealed glass. Fully tempered glass will meet the requirements of ANSI Z97.1 and CPSC 16 CFR 1201 and is considered a safety glazing material.

Quality Specification: 

Roller-wave distortion for 1/4″ glass – JEBs internal target is to maintain a limit of .003 peak to valley, excluding the lead and trail edges (10”) with an allowable .008”. Industry guideline for 1/4″ heat-treated glass suggest a tolerance of not to exceed .006” peak to valley, excluding the lead and trail edges (10”) with an allowable .010”.

Bow and Warp for 1/4″ glass can be targeted not to exceed 1/32″ per lineal foot.

Lead free colored ceramic frit enamel is applied by an automatic silk screen press system in a temperature and humidity controlled room and then fire-fused to the surface of the substrate glass in a horizontal oven at 1150°F to create a very durable and environmentally-safe Enviroscreen™ silk-screened panel.

• Lead free – No disposal problems
• Two standard colors
• Three standard patterns: dots, lines and holes
• Custom colors available(contact Sales Department)
• Custom patterns available(contact Sales Department)

Lead-free colored ceramic frit spandrel is applied with an on-line roller coater and fire-fused to the interior surface of the substrate glass (second surface) to create an environmentally safe Envirospan™ opaque panel.

• Lead Free – No disposal problems
• Five standard colors
• Factory applied polyester backing available for fallout protection

The five standard spandrel colors available for application onto 1/4″ clear heat-treated glass.

Custom colors and tinted or low iron substrates are available upon request. 1/4″ pyrolitic reflective glass is available in grey, bronze or blue with standard black frit on the #2 surface.
