If you’re in San Marino and want your home to feel safer and more comfortable—without altering its charm—window security screens are a smart and stylish upgrade. California Security Screens, Inc. (CSS) specializes in custom-fit window security screens in four main styles: Fire Escape, Fixed, Cleanable, and Casement. These screens offer robust protection for almost any window in your home. Made with aircraft-grade aluminum frames and premium stainless-steel wire mesh, our screens block up to 60% of UV rays, reducing heat and providing an extra layer of security to make you feel more at ease.
Fire Escape Screens for Bedroom Windows
Fire Escape screens are designed to meet emergency exit requirements for bedrooms, providing a safe, secure way out in an emergency. These screens mount on the exterior with a tamper-resistant frame to discourage forced entry. On the inside, a simple release bar lets you open the screen quickly when needed—secure from the outside and easy to operate from the inside when it matters most.
Fixed and Cleanable Options for Everyday Windows
Fixed screens are ideal for windows that don’t require emergency exits, such as those in living rooms, kitchens, dining rooms, and hallways. They’re also great for bedrooms with multiple windows or doors, offering strong protection. The only downside is that they can’t be opened to clean the windows.
Cleanable screens are perfect for fixed glass panels, allowing you to open the screen for easy window cleaning. Similar to Fire Escape screens, they feature exterior locks instead of an interior release bar, enabling you to unlock and remove the screen from the outside, clean the window, and then re-secure it for everyday protection.

Casement Screen Solutions for Specialty Windows
Casement windows require a different solution since they open outward. CSS offers two reliable options: the first is a Casement Security Window Screen, which mounts on the inside of the window frame. This screen opens inward, allowing you to crank open the casement window, then close the screen to secure it. Alternatively, we can install a fixed screen inside the casement frame, replacing the existing screen and keeping your window secure whether it’s open or closed. Either way, you’ll maintain your view, enjoy airflow, and have peace of mind.
