EXTERIOR WINDOW
SECURITY BARS

Why let them break the glass? Stop intruders at the perimeter with high-visibility, high-strength exterior mounting.

Secure The Perimeter

The Psychology of the Exterior Bar

Exterior window security bars work before the crime even starts. A criminal scouting a neighborhood looks for "soft targets"—homes with dark corners and unobstructed windows.

When they see steel mounted on the facade, the calculation changes instantly. It signals: "This house is hardened. It will take time. It will make noise." 95% of opportunistic thieves keep walking.

👁️ STOP

Where Should You Mount?

Choosing between interior and exterior mounting is critical for your security strategy.

Exterior Mounting

PROS:

Protects the glass from breakage.
Maximum visual deterrent.
Does not interfere with blinds/drapes inside.

CONS:

Exposed to weather (rust risk).
Harder to clean windows.

Interior Mounting

PROS:

Protected from weather.
Easier emergency exit operation.
Less "aggressive" look from street.

CONS:

Glass can still be smashed.
Thief doesn't see bars until close up.

Weathering the Elements

Since exterior window security bars live outside, they must fight rust. Cheap bars from big-box stores are often just painted metal that will streak rust down your siding in 6 months.

The Security WB Standard: We use hot-dipped galvanized steel or zinc-rich primer before applying a marine-grade powder coat. This double-layer protection ensures your security doesn't turn into an eyesore.

🌧️ RUST PROOF

Installation Warning ⚠️

Exterior bars must be anchored into the structural framing or masonry of the house, not just the decorative trim or siding. Security WB installers use 5-inch lag screws to penetrate through siding and sheathing deep into the wall studs.
