Security Screens for Aluminum Doors: A Practical Guide

What a security screen does and does not do

A security screen adds a second barrier in front of the door leaf. Its job is to slow down a forced entry attempt, protect the glass or panels from impact, and deter intruders who look for easy targets. It does not replace a good lock or a sound door frame, and no screen makes a home fully burglar proof.

Most homeowners use screens to protect a sliding or hinged aluminum door that has large glazed areas, or to keep a door open for ventilation while the house is unattended for a short time.

Main types of security screens

The common options differ mainly in how they look and how much they block the view:

• Flat bar grilles: strong, simple, and good for a clear view through the door.
• Decorative iron grilles: customized patterns that suit classic or modern facades.
• Mesh or perforated screens: give good airflow and privacy, with the fine mesh resisting tools and hands.
• Hinged or sliding security doors: a full second door that opens on its own frame.

Each type can be finished in the same colour family as your window frames, which keeps the building looking coherent.

Checking the door and wall before ordering

The screen is only as strong as its fixings. Before measuring, check that the aluminum door frame is firmly attached to the wall and that the surrounding masonry is sound. Hollow blocks, crumbling plaster, or a loose frame will undermine any screen, however heavy it is.

Note the opening direction, the handle position, and any protruding hardware, since these affect where the screen's frame and hinges can go. Taking photos of the door from inside and outside helps the planning step.

Measurement and drawing

An accurate on-site measurement is the foundation of a good screen. Our team measures the opening at several points, because walls are rarely perfectly square. We then prepare a drawing and a written specification showing the profile sizes, the grille pattern, the fixing points, and the finish.

Please review the drawing carefully before approving it. Changes are much easier at this stage than after production begins.

Fixings, anchoring and installation

Strong anchoring matters more than the grille itself. Fixings should go into solid structure and be sized for the load and the wall material. Frames should be level, plumb, and sealed against weather once fixed.

For the railing and guard elements we work with, the Israeli standard SI 1142 is a useful general reference, and exact dimensions and loads are checked with the engineer for each project rather than assumed.

Finishing and maintenance

Hot-dip galvanizing and powder coating protect steel grilles against rust, which is especially important near the coast and in humid weather. Aluminum screens need less protection but still benefit from a durable coating.

• Wipe frames with clean water and mild soap a few times a year.
• Check fixings and sealant once a year.
• Clear debris from tracks of sliding screens.

Frequently asked questions

Will a security screen make my aluminum door safe enough?

A screen adds a meaningful delay and deterrent, but it works best together with a good lock and a sound frame. Think of it as one layer in a wider protection plan.

Can I keep the door open for ventilation with a screen?

Yes, mesh and grille designs allow air to flow while the door leaf stays closed. The fineness of the mesh affects how much air and light pass through.

Do I need to remove the existing door to install a screen?

Usually not. Most screens are fixed to the wall or frame around the existing door, so the door itself can stay in place.

How do I know which screen type suits my home?

Start with the view and airflow you want, then check the wall condition. A site visit lets us recommend a design that fits both your needs and your building.

Common mistakes to avoid

Choosing a screen by look alone and fixing it into weak masonry is the most common error. Skipping the measurement and ordering from a rough estimate often leads to gaps and poor fitting.

Our recommendation

Have the wall and frame checked before you order, and insist on a written drawing with the fixing points marked. A well-anchored custom screen will outperform a heavier one that is poorly fixed.

Summary

A security screen is a practical outer layer for aluminum doors when it is custom measured, correctly anchored, and matched to the wall and frame. Plan the design together with the fixings for lasting protection.
