Security screen doors
Also called: security screens, metal security screens
Quick answer: a security screen door is a sliding screen built to keep people out, not just insects. It has a strong metal frame and a tough metal mesh that resists cutting and pushing. You can leave the glass door open for air while the screen stays locked.
- Spline, a rubber cord that presses the mesh into a groove
- Standard frame, thin rolled aluminum
- Clamp strip, screwed down in many security screens so the mesh cannot pull out
- Security frame, a thicker, heavier section

Questions people ask
Can I add a security screen to my sliding patio door?
Usually, if the door already has a screen track. The screen is made to fit the opening, and the track has to be straight for the lock to line up.
Do security screens block the view or the breeze?
Fine woven stainless mesh lets air through and keeps a fairly clear view. Perforated metal blocks more of the view but adds privacy.
Will a security screen stop a break-in?
It slows one down and adds a locked layer. It works best together with a strong lock and an anti-lift device on the glass door itself.
