About IWC Windows & Doors

International Window Corporation is a California-based vinyl window and door manufacturer with over 65 years of production history. IWC products are known for commercial-grade structural performance in a residential product — their Majestic Series meets commercial rating requirements (C30) and uses aluminum-reinforced sash frames as a standard feature, not an upgrade. IWC windows and doors are manufactured for strength, security, and long-term durability.

Frequently Asked Questions:

IWC Windows & Doors

Yes — International Window Corporation continues to manufacture vinyl windows and doors. IWC has been in continuous production since 1957 and remains one of California's longest-running window manufacturers. All American Door carries their current product line.
IWC's Majestic Series uses aluminum-reinforced sash frames and 100% welded corners as standard features — construction details that meet commercial rating requirements (C30). This gives the Majestic Series a structural advantage over many comparable residential vinyl windows. The Crown Series offers a more budget-accessible option with the same operating style range.
For IWC window parts including latches, locks, handles, and rollers, contact us at (714) 680-8999. We can advise on parts availability and whether replacement or full window upgrade makes more sense for your situation.
Energy Shield is IWC's high-performance Low-E glass used on the Lanai Series 5600 sliding door. It reduces ultraviolet light transmission and solar heat gain — reducing cooling load in Orange County's climate where solar exposure is a significant factor in home energy costs.
