New windows bring natural light, an updated look, and expansive views into your space. But they can also include features that can help keep your family safe — especially in homes with young children or multiple floors. The best replacement windows deliver on what matters most — stunning style, energy savings, and safety features that help provide peace of mind for you and your family.

Understanding window safety options
Modern replacement windows offer two main safety options for your windows — sash limiters and Window Opening Control Devices (WOCDs). Both options help provide protection without compromising your windows’ appearance or everyday use. They’re designed to work seamlessly with your daily routine, giving you peace of mind while maintaining the natural light and ventilation you expect from premium windows.

Sash limiters
Sash limiters offer straightforward protection for casement and awning windows, limiting them to a four-inch maximum opening while helping you meet building codes. They restrict how far your window can open, creating a natural safety barrier while still allowing ventilation. The four-inch opening provides adequate airflow — perfect for rooms where kids and pets spend time.

Window opening control devices
WOCDs offer the most advanced safety protection available. These devices also limit openings to four inches, like sash limiters. But WOCDs offer a two-action release system that automatically resets when you close the window. This release system requires deliberate, coordinated movement to open beyond the safe limit — something young children can’t easily manage, but adults can handle effortlessly.
