Larson SecurePRO Window Protection Panels

SecurePRO delivers break-in protection through stainless steel security mesh while maintaining year-round energy efficiency with self-storing glass panels. The system retrofits over existing windows, particularly valuable for ground-floor bedrooms and historic homes where traditional security bars would destroy aesthetics.

Skip these if you’re looking for budget storm windows or basic insect screening. SecurePRO’s mesh exceeds 1,000 pounds of impact force — this is serious security hardware disguised as a storm window.

Security Performance That Actually Matters

The stainless steel mesh uses 0.028-inch diameter wire woven at 12 weaves per square inch, delivering 800 pounds of tensile strength per linear inch. Those numbers translate to real protection — someone can’t cut through this with wire snips or kick it in during a break-in attempt.

Security Specification	Performance Rating
Mesh Impact Force	Exceeds 1,000 lbs
Frame Compression Force	15,000 lbs
Tensile Strength	800 lbs per linear inch
Wire Diameter	0.028 inches
Mesh Density	12 weaves per sq. inch
Standards Compliance	Exceeds SMA 6001-2002 impact-force standard

The physical mesh barrier provides protection that security film can’t match — film only reinforces glass, while SecurePRO adds an actual barrier. The mesh also allows ventilation while locked, solving the eternal summer dilemma of security versus airflow.

Energy Efficiency Beyond Security

Double-strength tempered glass comes standard, with optional Low-E glass panels available. The self-storing design means you’re not swapping glass for screens every season — both stay in the frame year-round.

UV filtration built into the mesh reduces fading — particularly valuable at Montana’s elevation where UV exposure hammers south-facing windows. The system retrofits over existing windows, adding an insulating air pocket that improves thermal performance without full window replacement.

Glass Options	Features
Standard	Double-strength tempered glass
Low-E Upgrade	Optional Low-E glass panels
Additional Option	Optional double-strength laminated glass

The real value shows in shoulder seasons. That dead air space between SecurePRO and your existing window acts like a thermal break, reducing condensation and heat loss. Unlike solid steel bars, you get a clear view plus added insulation — security that doesn’t make your house look like a fortress.

Installation Reality Check

Outside mount only with 4 tamper-proof one-way screws — once these go in, they don’t come out without destroying the screw head. The kit includes expander hardware for height adjustment and an integrated emergency release mechanism.

Installation steps: measure window opening width and height, round down measurements to the nearest 1/8” for custom ordering, secure the panel directly to the existing window frame using provided screws, then verify operation of the emergency release latch.

Dimension	Range
Width	24 1/8” - 54”
Height	14” - 90”
Standard Example	25” x 39.75”

The system fits over most existing residential window styles — single-hung, double-hung, sliders, basement, and fixed windows. That emergency release matters for bedroom installations where egress codes apply. Test it after installation and show everyone in the house how it works.

The tamper-proof screws create a double-edged situation. They prevent removal from outside (good), but also mean you’re committed once installed (consideration). This isn’t seasonal hardware you’ll swap out — it’s permanent security infrastructure.

Frequently Asked Questions

How does SecurePRO compare to window bars for security?

SecurePRO provides an unobstructed view compared to traditional security bars while offering break-in protection. The system combines typical storm window energy savings with high-strength security mesh. You get protection without making your home look institutional.

Can you still open windows with SecurePRO installed?

Yes — the mesh allows air flow while locked, providing ventilation with security. The self-storing glass panels slide or swing within the frame, giving you control over airflow and insulation.

What about fire escape requirements for bedroom windows?

SecurePRO includes an integrated emergency release system for quick escape. Always verify that any security product meets local egress codes for bedroom installations.

Is SecurePRO still available at retail?

Limited reviews note the product as “no longer sold” on some major retail sites like Lowe’s. Check with Larson directly or specialized security window dealers for current availability.

Does the stainless steel mesh rust in humid climates?

Stainless steel resists corrosion better than standard steel mesh options. The heavy-duty powder-coated aluminum frame provides additional weather resistance for long-term durability.
