Roll-Wave Evaluation Now Underway; Heat-Treated Glass Bulletin Published

The Glass Association of North America’s (GANA) Tempering Division Roll-Wave Subcommittee chair, Ren Bartoe of Vesuvius McDanel, has requested heat-treated glass fabricators take part in a “critical” evaluation of their ability to meet proposed values for maximum allowable roll-wave distortion, according to a report in GANA’s July/August 2002 newsletter.

  According to the report, Bartoe advised that responses to the product evaluation will “play a key role” in the actions to be taken on the standard test method and roll-wave specification at the subcommittee meeting taking place September 29 during GANA’s fall conference in New Orleans.
In other news, GANA’s board of directors and the Tempering Division have approved publication of the glass information bulletin, Heat-Treated Glass Surfaces are Different

According to GANA, the bulletin is targeted toward building owners, contractors and window cleaners, and addresses heat-treated glass usage trends, surface considerations, damage concerns and proper cleaning procedures. It can be downloaded from GANA’s website, www.glasswebsite.com.

Likewise, the association’s Laminating Division executive committee has announced that the Laminating Glass Design Guide will be reviewed and updated by the end of this year.

“With the increased usage of laminated glazing materials, it is critical that GANA maintain an up-to-date technical reference document addressing issues from design considerations to applicable standards,” said Rick Wright of Oldcastle Glass and Laminating Division chair. 

CSI Approves Concept for Revising MasterFormat

The executive committee of the Construction Specifications Institute (CSI) based in Alexandria, Va., has approved a concept for revising and expanding CSI’s 16-division MasterFormat specifications system.

According to CSI, under the decision divisions 15 (mechanical) and 16 (electrical) will be eliminated and the information formerly included in them will be incorporated in other divisions.

In addition, two new divisions in place of a proposed 17th division will address communications and life safety and facility protection. According to information from CSI, revision will broaden the base of potential users of MasterFormat, providing effective specification formats for heavy civil engineering projects and industrial construction. Doors, windows and glass remain in division 8.

ASTM IG Standards Now Available Online
The American Society of Testing Materials (ASTM) now has insulating glass standards available on its website, www.astm.org. The new standards are:

• E 2188-02 Standard Test Method for Insulating Glass Unit Performance, $30;

• E 2189-02 Standard Test Method for Testing Resistance to Fogging in Insulating Glass Units, $25; and

• E 2190-02 Standard Specification for Insulating Glass Unit Performance and Evaluation, $25.

NAHB Withdraws from NFPA Building Code; Council Issues NFPA 5000
According to a report in the International Code Council’s (ICC) June 2002 newsletter, the National Association of Homebuilders (NAHB) withdrew from development of the National Fire Protection Association’s (NFPA) 5000 Building Code on April 17. In a letter to former NFPA president and chief executive officer George Miller, NAHB “questioned the benefit to public health and safety of developing a second set of national building codes to compete directly with the ICC’s family of codes,” said the newsletter.

The ICC added that the NAHB letter noted that its policy “supports the concept of a single coordinated set of national model building codes that includes housing affordability as a major determinant in its development.”

Although the NAHB withdrew its involvement in the NFPA technical committees responsible for developing NFPA 5000, it plans to continue its participation in other NFPA codes and standards.
However, at a recent meeting of the NFPA Standards Council, the group voted to issue the NFPA 5000.

"NFPA codes and standards have served as key elements of building safety for many decades," said James M. Shannon, NFPA president and chief executive officer. "The issuance of a building construction and safety code developed through NFPA's ANSI-accredited process is a historic step in enhancing safety."

According to NFPA, upon publication, NFPA 5000 will be available for review online at www.nfpa.org

NFPA 5000 is part of the Comprehensive Consensus Codes™, which is expected to be complete in 2003.

ANSI and ICC Partner on Distribution of Int’l Codes
The American National Standards Institute (ANSI) and the International Code Council (ICC) have signed an agreement that granted ANSI the rights to distribute ICC’s International Codes via the ANSI Online Electronic Standards Store.

Initially, ANSI will offer a total of 14 ICC codes and standards in PDF format for users to purchase and download from the ANSI site. This number will increase with ICC’s release of new codes and standards.

In regard to these changes, the late William Tangye (see related story, page 67), ICC’s former chief executive officer said, “This agreement is reflective of the close working relationship between ANSI and ICC and our mutual desire to make building safety codes more readily available to a wider constituency, both domestically and internationally.”

NSA Submits Proposals at ICC Public Hearings 
At the 2002 International Code Council (ICC) public hearings, held April 6-19 in Pittsburgh, the National Sunroom Association (NSA) submitted two proposals affecting sunroom additions. 

Michael Fischer, NSA technical director, said the 2002 hearings were very successful for the association, as “proposals setting deflection requirements for sunroom addition elements were approved by both the IBC Structural Committee and the International Residential Code (IRC) Building and Energy committees. In addition, the International Energy Conservation Code (IECC) committee heard and approved NSA’s proposal that outlined prescriptive R-value requirements for opaque areas of sunroom additions. 

According to Fischer’s report in the NSA’s May 2002 newsletter, in response to the hearings some codes and standards language was altered. For example, under deflection, Fischer reported, “aluminum structural members that support aluminum panels or screening will have a maximum allowable deflection of L/60. Aluminum sandwich panels will have a maximum allowable deflection of L/120 for use in roof and walls of sunroom additions.”

Under energy, the language now says, “opaque roofs of thermally isolated sunroom additions will have prescriptive R-value requirements or R-19 or R-24, depending upon the climate region, and opaque wall areas will have a minimum of R-13. 

In addition, the term “sunroom” is now included in the IRC’s definition for skylights and sloped glazing, as well as in sloped glazing text found in 2404.2 of the IBC.
