Mo -
This is an
amendment to the following Declaratory Statements, to provide for specific
questions.
DCA10-DEC-220
(FL12573 - Hurricane Fabric)
DCA10-DEC-221
(FL11340 - Hurricane Fabric)
DCA10-DEC-222
(FL13271 - Eastern Metal - Corrected from American Shutter Systems Assoc.)
DCA10-DEC-224
(FL13910 - Ultratek Worldwide)
DCA10-DEC-225
(FL12888 - Ultratek Worldwide)
Here are
the specific Questions:
1. Does L/30 apply to fabric shutters?
Fabrics do not have a loss of performance with deflections. It is my understanding that L/30 only applys to rigid materials.
2. Under what circumstances would this product
be able to get a FL Approval for HVHZ?
Would this project be able to get an HVHZ approval for installations
that limited its use for NON-GLAZING installations, such as on the exterior of
non-glazed lanais, vents, doors - including garage doors, and any other
non-glazing installations?
3. Would this product be able to be considered
as part of a panel wall system, providing impact protection while maintaining a
separation between this product and the panel wall system.
4. Could this product be considered as a
structural component for use in the HVHZ?
5. Can this product be installed in the HVHZ and
protect glazing as long as the deflection of the fabric exceeds a separation to
glazing of 1 inch?
6. Please clarify the language in 1613.1.9:
"...shall provide a minimum clear separation from the glass of 1 inch
(25mm) but not to exceed 2 inches (51mm) when the shutter or awning is at its
maximum point of permissible deflection... " Specifically, what is the required
separation to glass, including any limitations such as maximum deflection. The language in 1613.1.9 says that the
separation to glass must be between 1 and 2 inches when at its maximum permissible
deflection. The 2 inches is mentioned
relative to clear separation, not relative to deflection as written. Some have said that there is a maximum 2 inch
deflection limit, but I have not found that language in the code. If that is an interpretation of 1613.1.9,
please explain it, the words do not support that definition to me.
7. In 1613.1.9, is the maximum deflection
L/30? Is it also another fixed amount
regardless of the span, such as 2 inches? If so, where in the code is this
written?
Thank you
Mo. If you have any questions, please
give a call.
Best
Regards,
John
