Proposals Heard During ICC Public Hearings
The International Code Council's (ICC) Code Development Hearings took place
February 22-March 4 in Cincinnati, Ohio. During the hearings numerous code change
proposals to the International Codes (I-Code), many of which could affect the
glass and glazing industry, were heard.
Following are some decisions of interest pertaining to the International Building
Codes (IBC) hearings:
Section 1604.3: a proposal to provide for the use of the same
deflection limits for skylight and sloped glazing framing in sunroom panels, was
Section 1609.14: a proposed change to require impact-resistant
glazing or impact resistant coverings in wind-borne debris regions, was approved;
A proposed change to section 2405.5 for unit skylights was approved
so the code chapter will now cite the new specification AAMA/WDMA/CSA 101/I.S.2/A440;
A proposed change to update chapter 35 of the IBC to reference
ASTM E 1300-04 was approved;
A proposed change to section 2406.1.2 that would permit the
use of wired glass in occupancies other than group E (educational) was not approved.
Also disapproved was a proposal to section 2406.5 that would
have required safety glass to have visible markings to prevent impact.
The one proposal to the International Existing Building Code that concerned
glass was also approved. The proposal to chapter 3 requires replacement glass
to meet new installation requirements.
A number of proposals relating to glass and glazing were also heard pertaining
to the International Building Code, Fire Safety:
A proposed change to section 706.7 was approved. The proposal
permits fire-rated glazing that is used in atria to be exempt from the 25-percent
restriction on the amount of glazing permitted in fire barriers;
A proposed change to section 713.4 was not approved that would
have reduced the perimeter fire barrier system performance to 30 minutes when
curtainwall is not required to have a fire-resistance rating;
Also for section 713.4, a proposed change to reference ASTM
E 2307, Standard Test Method for Determining Fire Resistance of Perimeter Fire
Barrier Systems Using Intermediate-Scale, Multi-story Test Apparatus, instead
of the current description, was approved;
A proposed change to section 715.3 to permit alternative methods
for determining fire-protection ratings similar to those permitted for fire-resistance
ratings was approved, but a proposal to require an "R" or "P"
classification based upon whether the product provides a fire resistance or fire
rating was not approved;
A proposed change to 715.4 was withdrawn. The proposal would
have limited the area of glazing in exterior walls where the fire protection rating
is more than 90 minutes;
A proposal to section 404.5 of the IBC, General was withdrawn.
The proposal would have permitted the use of 20-minute fire protection rated glazing
(with the hose stream) to be used instead of the wetted glass assembly in atria.
