Arlington, Va.-based Oldcastle-Arpal LLC has released blast mitigation window systems that can be fabricated as fixed windows, tilt and turn, hinged, curtainwall applications and retrofit products for the special requirements mandated by landmark and historical preservation projects.
In collaboration with government agencies and private blast consultants, Arpal window systems have been extensively researched and tested through a variety of methods of full-scale blast testing.
Using an energy-absorbing system approach, the specially designed window and frame ‘give’ when struck by blast impulse protection.
The company says that the energy from the blast is absorbed within the glazing system, transferring virtually no ‘loads’ to the surrounding wall structure.

Fresno, Calif.-based Pinnacle Armor now offers the dual-functioning Secura Glaze patented framing system designed for use in securing primary or secondary security glazing or as a remedial anchoring system for P.E.T. safety films and security laminates.
The system is designed for security glazing retention that meets the requirements of security glazing manufacturers’ specifications for a frame that has a 1-inch bite on all sides of the glazing.
The company says that this design precludes pullout from the flexing of the glazing during blasts, forced-entry threats or natural disasters. It has bolt-on capability to accommodate standard security glazing nominal thicknesses of ¼-inch, ½-inch, ¾-inch and 1 ¼-inch, by an adjustment built into the base and sub-base.
Secura Glaze has passed the 4 and 10 PSI Army Corps of Engineers blast tests and achieved a GSA level II performance classification.
The company also has available the Blast Lite™ fully operable, hinged, secondary window/door system for blast mitigation. Featuring a multi-point locking mechanism with four-sided tumbler “pick-proof” locks, the mechanism is machined from a solid stainless bar for the utmost in strength and aesthetics.

Technical Glass Products (TGP) of Federal Way, Wash., has announced that Pilkington Pyrostop™ glass with 3M SCLARL 400 film provides security as well as fire protection. The coupling has received a level III bullet-resistant rating, indicating that it can stop a bullet from a .44 Magnum.
Literature from the company states that many types of protective glazing are highly flammable, resulting in large amounts of smoke and flames that can cause further damage to life and property. TGP says that Pyrostop addresses both problems and is designed for use in locations such as stairwells and elevator lobbies in which controlling the transfer of heat produced by a fire is of the utmost importance.
The company also offers schools replacing wired glass with an alternative fire-rated glazing material. FireLitePlus® is the laminated, impact safety-rated version of the wireless, fire-rated glass ceramic FireLite. FireLite Plus meets impact safety standards that surpass those of wired glass, including CPSC 16 CFR 1201 Category II (400 fpi), according to the company.
The fire-rated glazing carries fire ratings up to three hours indoors and up to 90 minutes in other applications. Listed with Underwriters Laboratories, FireLite Plus fits in TGP’s narrow profile Fireframes® as well as standard fire-rated hollow metal framing.

Hope’s Windows Inc. now offers the Liberty Series blast-resistant steel window, which meets the General Services Administration’s security criteria for level C blast-resistant windows.
“The Liberty steel window represents our response to the growing need for added security and protection in today’s environment and our commitment to safety, quality and distinction. In every test we performed, the Liberty steel window met or exceeded all safety standards set forth,” said Randy Manitta, vice president of sales and engineering at Hope’s Windows Inc.
Grand View Glass & Metal of Ontario, Calif., has completed testing of its new all-glass, P-style, 20-minute fire-rated door to meet NFPA 80 standards.
In addition to meeting the 20-minute standard, the company’s door conforms to ANSI Z97.1-1984 and the CPSC 16 CFR 1201 Category Two safety standards.
The company says that it is the only herculite-type door to achieve the fire rating.

C.R. Laurence Co. Inc. (CRL) of Los Angeles has introduced its transparent bullet-resistant barrier system, which is available as a complete, specified system or as components that can be purchased separately.
The barrier system includes surround-sound spacers in two styles and ten different styles of clamps for retaining just about any custom-designed, bullet-resistant barrier. Clamps are designed to work with materials such as level one 1 ¼-inch acrylic or level three 1 ¼-inch Lexgard. An optional two-piece snap-together sash is also available to secure the top and sides of the barrier if desired. One-and-one-fourth-inch aluminum U-channels are also available for running along the bottom edge of the glazing when deal trays are in countertops.

Integral Seal Mfg. Inc. of Concord, Ontario, has made a name for itself in the market with its four-corner, bent thermal-edge spacer. The company manufactures insulating glass (IG) units using thermal edge spacers from BayForm, a warm-edge spacer with a “U” channel and an engineered polymer bridge. The units are double sealed with either polysulphide or silicone and can be complemented with low-E glass in hard or soft coatings.
The company’s drive for developing the technology needed to devise a system for manufacturing the four-corner, bent warm-edge spacer stemmed from the desire to avoid the use of four-corner mechanical fastening, often considered the “weakest link” of many IG units. Company president Ben Nayot worked closely with an engineering firm to construct the bender necessary for the spacer’s construction.
“The corner on the spacer bar is the weakest link and I need to control the width of the corner. By using four-corner bends, I can avoid mechanical fastening of the corner,” said Nayot. The company also says that its new bent spacer gives the IG unit greater strength in areas where it is most vulnerable.
In addition to its spacer, Integral Seal’s computer order-entry system has revolutionized the way window components are ordered. Customers send in orders electronically that are received automatically and invoiced by the computer system. Pertinent manufacturing information is then transmitted to the company’s fully computerized glass cutting and metal forming machines, which the company says can eliminate human error in the inputting or data entry process.
“All of my customers’ computers are on a network that is linked to a mainframe, eliminating any need to relay that information from the customer to the CNC cutting machine and the bending machine. Therefore, it is not necessary to train employees or hire qualified operators, since the machine operator is required only to feed in the right material and press a button,” said Nayot.
