Gerkin Patio Doors by AWP
The Comfort Series 4400 sliding glass door has been transformed from a great door to being an unbelievable door! Our second-generation door has even surprised those who are not easily impressed.
Available Patio Door Styles:
We wanted a door that out shines all other sliding doors in weather tightness, ease of operation and long-term high performance. We got what we were looking for. This door features unbelievable strength against the elements with multiple areas of heavy internal aluminum reinforcements and multi-chambered fusion welded vinyl. Fixed transoms and side lites are also available for the 4400 patio door.
