Anlin Windows Series

Window Styles

Window style is a daily-use decision that determines how the window opens, how the room ventilates, and how the finished project matches your home’s exterior. The right choice depends on the room, wall space, sun exposure, and your day-to-day expectations.

 

In HOA communities, style and layout often matter as much as performance, so the goal is a window plan that looks consistent from the street while still delivering the airflow and usability you want inside. United Builders helps homeowners choose styles that make sense in real living spaces, then keeps layouts consistent across the project so the home looks intentional and stylish.

Custom Configurations

Built for Complex Work

With General Building (B) and Glazing (C-17) classifications, United Builders manages the full scope under one roof- including carpentry and finish work.

Not every project is a straight replacement. Some homes need larger openings, multi-window combinations, or a more balanced exterior layout that improves curb appeal.

Custom configurations can address remodel goals such as expanding a kitchen sink window, creating a wide opening for a living room view, or reworking the window layout to better fit a room’s furniture plan.

Window Options

Finishing details are where a window package becomes “right for the house.” Hardware, frames, grid patterns, and glass choices help match your neighborhood, align with HOA standards, and dial in comfort for each room.

Color options to match your exterior and interior design preferences.

Choose from a range of finishes and styles that complement your home’s aesthetic.

Traditional, colonial, prairie, or custom grid patterns for period homes.

Performance glass for energy efficiency, privacy, and UV protection.
