Practical Ventanas Cortizo guide

Window security: what to check

Practical guide to hardware, locks, laminated glass, shutters and opening types to improve home security.

Security is a system

Security depends on frame, hardware, locking points, glass, shutters, installation and accessibility. A ground-floor window needs a different approach from an upper window.

Hardware and locks

Multiple locking points, lockable handles and reinforced hardware make forced opening harder.

Laminated glass

Laminated glass helps keep the pane together after impact. It can be advisable for ground floors, balcony doors and exposed openings.

Shutters and access points

A well-integrated shutter can add another barrier. Also review patios, terraces and hidden windows.

What to request in the quote

Ask for locking type, handle, glass, expected security level, shutter options and recommended reinforcements for each opening.
