		<description>Mark,

I am installing a glass wall and a glass railing around a rooftop patio.  

The glass wall will have glass panels 4 foot wide and 6 1/2 foot tall.  The framing has been determined by a licensed structural engineer.  4 inch by 4 inch HSS tube will be used for vertical and horizontal pieces.  I need the glass to meet the following capabilies.

1) Withstand a wind load of 90 miles per hour for 3 seconds.
2) Withstand a line load of 200 lb

The glass railing will have glass panels 5 1/2 foot wide and 4 foot tall.  The framing has also been determined by licensed structural engineer.  I need the glass to meet the following capabilities.

1) Withstand a line load of 200 lb

QUESTIONS:
1) Can tempered glass work for both scenario&#039;s?  If so, what thickness?  
2) Can laminate glass work for both scenario&#039;s?  If so, what thickness?

Thank you in advance for your assistance.
