Ameristar Windows & Doors engineers thermally broken Thermo-Bridge Aluminum door systems that combine modern, narrow sightlines with code-ready energy performance. Paired with advanced Low-E3 insulated glass, these doors meet or exceed California Title 24 (2022) targets while delivering smooth operation in large openings. The AUC Series supports expansive panels over 50 square feet in sliding, folding, and pocketing (“hidden”) configurations that complement contemporary Southern California design.

Superior Performance.
Insulated Glass Unit
A substantial Insulated Glass Unit (IGU) improves thermal control and reduces outside noise, delivering consistent comfort without sacrificing daylight.
LoE3 Glass Package
The LoE3 glass package lowers ultraviolet and heat transmission through the door, helping protect interiors and manage solar gain in sunny exposures.
Argon Gas Filled Chambers
Argon gas filled chambers slow heat transfer between panes, boosting insulation and supporting better energy efficiency year round.
