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
