PGT Vinyl Sliding Glass door.

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 NFRC Certification
