Why We Use AstroGuard for Hurricane Protection

At West Shore Construction, one of the most common questions we get from homeowners is, “Why do you use AstroGuard instead of polypropylene hurricane fabric?” It’s a fair question—especially when both materials are widely available. The simple answer? We want the strongest, most dependable hurricane protection for your home.

While polypropylene works in certain conditions, AstroGuard’s ballistic-rated nylon with a ceramic coating offers significantly better strength, longevity, and overall peace of mind. In this post, we’ll walk you through the differences between the two and explain why AstroGuard is the standard we trust and install.

What Is Hurricane Fabric—and Why Does It Matter?

Hurricane fabrics are designed to shield windows, doors, and other openings from high winds, debris, and water intrusion during a storm. Unlike metal panels or plywood, these fabrics are lightweight, easy to install, and unobtrusive when not in use. But not all hurricane fabrics are created equal. The material you choose can directly affect how well your home is protected in a storm.

Understanding Polypropylene Fabric

Polypropylene is a synthetic, woven material used in some hurricane screens (e.g., AstroFlex). It’s lightweight, budget-friendly, and easy for homeowners to install themselves.

Pros:

• Affordable:Polypropylene is an economical option for basic protection.

• Light Transmission: It allows in some natural light—helpful during power outages.

• DIY Friendly: Lightweight and easy to install with minimal tools.

• Code Compliant (some zones): Meets Florida Building Code for impact resistance in many areas—but not all.

Cons:

• Not HVHZ Approved: Polypropylene doesn’t meet the standards for High Velocity Hurricane Zones like Miami-Dade and Broward Counties.

• Lower Strength: With reduced burst resistance, it struggles against large debris impacts or sustained wind pressure.

• UV Degradation: Without special coatings, it can break down over time under Florida’s harsh sun.

• Slight Porosity: About 5% porous, which means some wind or water could still pass through.

Bottom line? Polypropylene may work in lower-risk areas, but it doesn’t provide the robust protection needed when facing Category 4 or 5 storms.

Why We Use AstroGuard: Strength, Durability, and Real Protection

AstroGuard is a ballistic-rated nylon fabric coated with UV-resistant ceramic. It’s engineered specifically to defend homes from the most severe hurricane conditions—and it shows in both lab testing and real-world use.

Here’s why we trust AstroGuard for our clients:

1. Superior Strength

AstroGuard has a burst strength over 1,500 lbs per square foot—that’s up to 55% stronger than most fabrics, and even stronger than some metal panels. It’s been tested to stop large missile impacts and maintain structural integrity even at stress points like corners.

2. 100% Non-Porous

Unlike polypropylene, AstroGuard blocks all wind and rain. This helps prevent interior damage and reduces the risk of roof lift due to interior pressurization during high winds.

3. UV and Weather Resistant

Its ceramic coating resists sun damage, so it holds up season after season—even in Florida’s intense heat and humidity.

4. Lightweight & Easy to Install

At only 11 oz per square yard, it’s just as manageable as polypropylene. Plus, AstroGuard’s patented clip system grips without tearing, allowing for quick installs using just a screwdriver.

5. HVHZ Approved

AstroGuard meets Florida Building Code and Miami-Dade County standards, meaning it’s approved for use in High Velocity Hurricane Zones.

6. Cost-Effective Long-Term

With its added strength, insurance savings, and long-term durability, it’s a solid investment.

7. No Permanent Hardware Needed

AstroGuard installs temporarily and stores easily. No unsightly tracks, no rusting hardware—just protection when you need it.

Real-World Performance

AstroGuard isn’t just impressive in lab tests—it performs in the field. During a hurricane in Haiti, a medical clinic protected with AstroGuard reported minimal water intrusion and reduced wind noise. Here in Florida, it’s trusted by thousands of homeowners and recognized by insurers like Chubb, Citizens, and Fireman’s Fund.

In fact, using AstroGuard could help lower your insurance premiums by up to 40% depending on your provider.

Why We Don’t Recommend Polypropylene

While polypropylene may seem appealing at a lower price, it simply doesn’t hold up under the same pressures. Here’s how it compares to AstroGuard:
