Designed with security and aesthetics in mind, Harmony's range of security doors are manufactured from specially tempered, recyclable aluminium, which are sturdy, elegant and rust resistant. Choose from a range of options, including One-Way Mesh, which is specifically designed to provide protection from persistent pets but also offers added security by limiting visibility from the outside whilst maintaining a view from inside. Flyscreens are available for both security doors and windows.

The strong, yet lightweight, security doors can also be fitted with an optional three-point safety lock, which features three interlocking security hinges to deter opportunistic intruders.

Harmony's security doors are available in a full range of polyester powdercoat finishes, which makes it easy to match the door to the frame.
