Pilkington Pyrostop™ Now Available with Integrated Blinds
Pilkington Pyrostop™ fire-rated glass is now available with integrated Venetian blinds to enhance privacy and reduce glare. In instances where users want to control the amount of light entering a space or visibility into the space, Pilkington Pyrostop products with 45- and 60-minute fire ratings can be combined with manually operable Venetian blinds included in an insulated glass unit. Usable in interior spaces, Pilkington Pyrostop with integrated blinds is well suited for glazed office fronts within buildings, conference room windows, private offices, lobbies and other similar uses. The blinds are encased between multiple layers of glass, so they never need to be cleaned. In addition, the blinds are available in a wide range of colors and are fabricated in the U.S., allowing for short delivery lead times. To learn more, contact email@example.com.

Case Study: Fire-rated Curtain Wall Enhances IMAX® Theater Adjacent To Home of the Spruce Goose
To comply with a mid-construction staircase design change to the IMAX® theater building on the Evergreen Aviation and Space Museum campus, Scott/Edwards Architecture LLP used Pilkington Pyrostop™ fire-rated glass, Fireframes® Curtainwall Series fire-rated frames, and 90-minute Fireframes® Heat Barrier Series doors to meet various design and code requirements. Using the combination of fire-rated products allowed the architects to efficiently redesign one of the existing open staircases to provide a fire-safe exit that looks identical to a second, non-fire-rated glass staircase enclosure, which integrated well with the overall design.

Fire-Glass Testing Requirements Help Ensure Life and Property Safety
Today's fire-rated glazing products play a critical role in blocking the spread of flames and smoke, helping minimize building damage and providing time for occupants to exit the building and for fire fighters to arrive and extinguish the fire. As with other building materials that provide for life and property safety, fire-rated glass is subjected to a number of testing requirements. Using products that do not pass mandatory tests can put people's lives at risk and create liability for architects and specifiers. When selecting fire-rated glazing, it is important to remember two sometimes overlooked testing requirements that are reflected in building codes: 1) ability to pass a hose stream test, and 2) offer multi-directional fire protection.
Hose stream test: For fire ratings of 45 minutes or longer in the United States (and for all fire ratings in Canada), glazing must pass a required hose stream test, as well as a fire test. After being heated in a furnace following a standard time-temperature curve per National Fire Protection Association (NFPA) test standards, glass is immediately sprayed with water from a fire hose using a standard hose size and pressure. To successfully pass the test, the glass and framing must remain intact. This is a critical portion of testing requirements, because as NFPA 257 states, "The cooling, impact, and erosion effects of the hose stream provide important tests of the integrity of the specimen being evaluated."
Multi-directional fire protection: Some glazing materials rely on a coating on one side of the glass to reflect heat away during a fire. Such directional materials only provide protection from one side, requiring the architect or contractor to decide from which direction a fire might start - a nearly impossible task. Unless you are 100% certain you can predict where a fire will originate, you risk offering no protection where it will be needed. IBC section 715.5.2 requires that nonsymmetrical glazing be tested with both faces exposed to the furnace, and the assigned fire protection rating shall be the shortest duration obtained. Products that require that a specific identified side be installed facing the direction of the expected fire attack do not meet this requirement.
Check product listings and labels carefully to ensure that products you specify meet these, and other testing requirements. Any footnotes or exceptions stating that a material does not meet all tests, or that require special approvals, should be eyed with caution.

New California Building Code Affects Fire-Rated Glazing
As of January 1, 2008, the State of California adopted a new building code that is modeled after the 2006 International Building Code (IBC). The new California Building Code eliminates the use of traditional polished wired glass in hazardous locations where it is susceptible to impact and breakage, such as doors, sidelites and windows near the floor. Now, fire-rated glass in these locations must also be impact safety rated to meet CPSC 16CFR1201.
Fortunately, there are now many alternatives to traditional wired glass that offer superior fire and impact protection, as well as the aesthetic advantages of being clear and wireless. The FireLite® family of clear ceramic glass products - the industry-leading standard for fire-rated glass for more than a decade - is available through local distributors in your area.
