Profile: PatioDoorFactory.com specializes in vinyl patio doors. We manufacture vinyl windows and patio doors. Our standard vinyl patio doors are usually 72" or 96" inches wide by 80" inches high. Vinyl frames teamed up with dual-pane insulating glass reduce energy lost through conduction. Radiant heat loss is decreased with LoE272 glass, which reflects radiant heat 85% more than clear glass and comes standard on all our patio doors. Optional LoE366 glass blocks 95% of radiant heat. Our doors are tested to meet stringent forced entry standards. A patio door with dual-glazing is more sound resistant than single-pane patio doors. We also specialize in custom patio doors. Sliding patio doors operate with ease and allows to take full advantage of the outdoor living space. These doors are fully assembled with either a right or left operating panel and open by sliding along horizontal track at the bottom for easy operation.
