Experts give high ratings to fiberglass, folding and swinging patio doors. Fiberglass patio doors require little to no maintenance and are impermeable to moisture. They are energy-efficient, are weather-resistant and do not rust or rot. They also provide a clear view, reports ExteriorMedics.com.
Folding patio doors add a note of sophistication and beauty by providing a modern look. They are also appropriate for tight spaces and have an extended lifetime. Such patio doors come with special locking systems and extra-strong latches that enhance their overall security. Swinging patio doors are a good fit for patio views and backyards, according to QualityWindowandDoorINC.com.
