I have fielded alot of questions about sliding glass door replacements. Here is a PGT vinyl framed slider, Double pane glass with Low E coating, Argon gas fill. The door installed (normal difficulty) is $1500 to $1700. The grid is optional.
PGT also makes Impact (hurricane) sliding glass doors like this one.
PGT Aluminum Windows and Doors have been tested to Miami-Dade protocols and/or AAMA/NWWDA 101/I.S.2.7 specifications. They have also been designed to meet the following test standards:
ASTM E283 for air infiltration
ASTM E987 for deglazing
ASTM E547/E331 for water resistance
AAMA 1302.5 for forced entry for operable windows
AAMA 1303.5 for forced entry resistance for doors
ASTM E330 Uniform Structural Load Test
