Although the concept of component based rating of door assemblies
is one that AAMA itself has pursued
actively over the past few years, it is
one that is proving to be complex.
Testing conducted by the AAMA
door council has found the methods
proposed for consideration by ICC
during this cycle were overly simplistic and did not adequately address
all the nuances that needed to be
addressed.
SKYLIGHTS
The definition of tubular daylighting devices that currently exists in
AAMA/ WDMA/CSA 101/I.S.2/A440
will appear in the 2012 IRC and
2012 IBC, along with clarification
that these devices are to be tested
and labeled in accordance with that
standard. At the present time, unit
skylights are required to be tested
and labeled in accordance with
the same standard in both the IRC
and IBC. Unit skylights will also be
exempt from a requirement of the
IRC and IBC for saddle or cricket
flashing of large roof openings. It is
more appropriate for the installer of
these skylights to instead rely upon
the installation instructions of the
skylight manufacturers, as currently
occurs for windows.
Proposals that would have required all skylights to be protected
by a guard or screen that is capable
of resisting a 200 pound load, or
for the skylight itself or screen
protecting it to be able to resist an
800 ft-lb impact load representative
of a falling body part, were disapproved. Also disapproved was a
proposal that would have required
all plastic dome skylights to be
subject to a Class B burning brand
test, regardless of the materials
used for the dome or framing.
