How to Protect from Broken Glass During Storms: Complete Safety Guide

When severe weather strikes, broken glass becomes one of the most dangerous hazards in homes and buildings. Flying shards can cause serious injuries, property damage, and create hazardous cleanup situations. At Batten Emergency, we’ve seen firsthand how proper preparation before a storm can dramatically reduce these risks and keep your family safe.

During hurricanes, tornadoes, and severe thunderstorms, windows and glass doors are particularly vulnerable. According to the Insurance Institute for Business & Home Safety, windborne debris is responsible for approximately 80% of all window damage during hurricanes. This comprehensive guide will walk you through proven methods to protect yourself, your family, and your property from broken glass during storms.

Understanding the Danger: Why Broken Glass is a Serious Storm Hazard

Before diving into protection methods, it’s important to understand why broken glass poses such a significant threat during storms. When windows break during high winds, several dangerous situations occur simultaneously:

Flying glass shards can cause deep lacerations, eye injuries, and other trauma
Broken windows allow wind, rain, and debris to enter your home
Pressure changes from broken windows can damage your home’s structural integrity
Post-storm cleanup of glass creates additional injury risks
Water damage from rain entering through broken windows can lead to mold and property damage

Our emergency preparedness experts have observed that many homeowners underestimate both the likelihood of window breakage and the extent of damage it can cause. In hurricane-force winds, even small objects can become dangerous projectiles capable of shattering standard windows. Understanding these risks is the first step toward effective preparation.

Permanent Window Protection Solutions

For homes in storm-prone regions, investing in permanent window protection solutions offers the most reliable defense against broken glass. These options provide consistent protection without requiring last-minute installation before each storm:

Impact-Resistant Windows:

Impact-resistant windows feature laminated glass that holds together when shattered, similar to a car windshield. These windows have a strong polymer layer sandwiched between glass panes that prevents the glass from breaking into dangerous shards. According to a study by the Federal Emergency Management Agency (FEMA), homes with impact-resistant windows experienced 60% less damage during hurricane conditions compared to homes with standard windows.

Provides 24/7 protection without pre-storm preparation
Offers additional benefits including improved energy efficiency and noise reduction
Meets stringent building codes in hurricane-prone regions
Available in various styles to match home aesthetics
Can potentially reduce insurance premiums in some areas

In our experience working with homeowners in coastal regions, impact-resistant windows represent one of the best long-term investments for storm protection. While the upfront cost is higher than temporary solutions, the convenience and reliability make them worth considering, especially if you live in an area that faces multiple storm threats each year.

Storm Shutters:

Storm shutters provide a robust physical barrier that protects windows from flying debris and high winds. Available in several styles, they can be permanently mounted to your home while offering different levels of convenience and protection:

Roll-down shutters: Operated manually or with a motor, these aluminum or steel shutters roll up into a box above the window when not in use
Accordion shutters: Permanently attached to the sides of windows and manually pulled closed when needed
Bahama shutters: Hinged at the top and propped open when not in use; provide shade and quick deployment
Colonial shutters: Decorative shutters hinged on the sides that can be closed before storms

Our team has found that accordion and roll-down shutters offer the best combination of protection and convenience, especially for elderly homeowners or those with physical limitations who might struggle with temporary panel installation.

Security Window Film:

Security window film is a layer of polyester film applied to existing windows. While not as protective as impact-resistant glass or shutters, it provides an additional layer of safety by holding shattered glass together:

More affordable than full window replacement
Can be professionally installed on existing windows
Reduces the risk of flying glass shards if windows break
Available in various thicknesses (4-15 mil) with thicker films offering better protection
May provide some UV protection and energy efficiency benefits

Based on our field testing, we recommend security films of at least 8 mil thickness for storm protection. While these films won’t prevent windows from breaking under direct impacts, they significantly reduce the danger from flying glass by keeping the shards attached to the film.

Temporary Window Protection Options

When permanent solutions aren’t feasible due to budget constraints or rental restrictions, temporary protection methods can still provide effective defense against broken glass during storms. These solutions require installation before each storm but can be removed and stored afterward:

Plywood Coverings:

Plywood remains one of the most common and cost-effective temporary window protection methods. The Federal Alliance for Safe Homes (FLASH) recommends using at least 5/8-inch exterior-grade plywood for storm protection. When properly installed, plywood can prevent most storm debris from breaking windows.

Use exterior-grade plywood (CDX) at least 5/8-inch thick
Cut panels to overlap window frames by 8 inches on all sides
Pre-drill installation holes and mark panel locations for quick installation
Secure with 1/4-inch lag screws into solid wood (not just the trim)
Store panels flat in a dry location between storm seasons to prevent warping

Our specialists emphasize the importance of proper anchoring when using plywood. Many homeowners make the mistake of securing panels only to window trim rather than to the structural framing of the house, significantly reducing effectiveness. Pre-drilling and labeling panels before hurricane season begins can save critical time when a storm approaches.

Storm Panels:

Storm panels are corrugated metal or polycarbonate panels that attach to permanent tracks or bolts around windows. They offer several advantages over plywood:

Stronger and more durable than plywood
Reusable for many storm seasons
Easier to store than bulky plywood sheets
Metal panels provide superior impact resistance
Clear polycarbonate panels allow light to enter while providing protection

What our emergency preparedness experts have seen work well is having a combination of panel types—metal panels for most windows and clear polycarbonate panels for at least one window per room to allow some natural light if power is lost during the storm.

Fabric Storm Panels:

Engineered fabric storm panels are a newer alternative made from PVC-coated polyester or similar materials. These lightweight screens are designed to catch and deflect flying debris:

Significantly lighter and easier to handle than plywood or metal
Can be installed by one person
Allow some light transmission and visibility
Can be folded for compact storage
Some products are rated for hurricane-force winds

In our field testing, fabric panels like AstroGuard or Fabric-Shield performed surprisingly well against moderate debris impacts. They’re particularly useful for upper-story windows where installation of heavier materials might be challenging or dangerous.

Emergency Window Protection When a Storm is Imminent

Sometimes storms develop quickly or change direction unexpectedly, leaving little time for ideal preparations. In these emergency situations, there are still actions you can take to reduce the risk of broken glass injuries:

Emergency Taping Techniques:

While window taping has limitations, there are specific situations where it can help. The key is understanding that tape won’t prevent windows from breaking, but it may reduce the scatter of glass fragments:

Use heavy-duty duct tape or packing tape (never masking or painter’s tape)
Apply in a “starburst” pattern from the center outward
Cover the entire window with overlapping strips
Extend tape several inches onto the window frame
Consider combining with temporary window coverings on the interior

Our team always recommends treating taped windows as a last resort, not a primary protection method. Based on our experience with post-storm assessments, taped windows that break can sometimes create larger, more dangerous shards than untaped windows. However, in an emergency situation with no other options, proper taping is better than nothing.

Interior Barriers:

When external protection isn’t possible, creating interior barriers can help protect occupants from flying glass:

Close all interior doors to compartmentalize the home
Hang heavy blankets or quilts over windows from curtain rods
Move furniture like bookshelves or mattresses in front of windows
Designate an interior room with minimal or no windows as a storm shelter
Consider using tables or sturdy furniture as protective barriers

What our experts have seen work well in emergency situations is creating a “safe room” in an interior bathroom, closet, or hallway where family members can shelter during the worst of the storm. This approach acknowledges that some windows may break but focuses on keeping people away from the danger.

Personal Protection from Broken Glass

Beyond protecting your windows, it’s crucial to prepare for the possibility that glass may still break during extreme conditions. Personal protection measures can significantly reduce injury risk:

Protective Clothing and Gear:

Having appropriate protective gear ready before a storm can prevent injuries if you need to move through areas with broken glass:

Sturdy closed-toe shoes or boots with thick soles
Heavy work gloves (leather or cut-resistant)
Long pants and long-sleeved shirts made of thick material
Safety glasses or protective eyewear
Hard hat or bicycle helmet if there’s risk of falling debris

In our experience helping families prepare emergency kits, protective gear is often overlooked in favor of food and water supplies. We recommend storing a complete set of protective clothing for each family member with your emergency supplies, including properly sized footwear for children who may outgrow shoes between storm seasons.

Safe Locations During a Storm:

Knowing where to shelter within your home can be lifesaving during severe weather events:

Choose an interior room on the lowest floor, away from windows
Bathrooms, closets, or hallways often provide the best protection
Stay on the side of the building facing away from the wind direction
Keep at least one solid wall between you and the nearest windows
Avoid rooms with large mirrors or glass furniture

Based on our field testing and emergency response experience, we’ve found that many storm injuries occur when people move to windows to observe conditions. Our specialists emphasize the importance of staying in your designated safe area until the storm has completely passed, even during seemingly calm periods that might actually be the eye of the storm.

After the Storm: Safe Cleanup of Broken Glass

Once the storm has passed, careful cleanup of broken glass is essential to prevent injuries. According to the CDC, post-disaster injuries often occur during cleanup activities. Follow these safety protocols:

Immediate Safety Measures:

Before beginning cleanup, take these precautions to ensure safety:

Wear appropriate protective gear including closed-toe shoes, gloves, and eye protection
Keep children and pets away from areas with broken glass
Ensure adequate lighting to see glass fragments
Be aware of glass that may have been thrown far from windows
Check for glass in unexpected places like furniture, bedding, and clothing

Our team always recommends documenting damage with photographs before cleanup begins, as this can be important for insurance claims. Be particularly cautious about glass that may have landed in carpeting or upholstery, as these tiny fragments can cause injuries long after the storm.

Effective Cleanup Techniques:

Proper techniques for glass cleanup can prevent both immediate injuries and future problems:

Large fragments: Pick up carefully with gloves and place directly in a puncture-resistant container
Small fragments: Use a broom and dustpan rather than a vacuum (which can spread tiny shards)
Embedded glass: Use duct tape pressed onto surfaces to lift tiny fragments
Carpet cleanup: Use a commercial wet/dry vacuum specifically designed for glass
Disposal: Wrap glass in newspaper, place in a sturdy container, and label clearly before disposal

In our experience helping with post-storm recovery, we’ve found that multiple cleaning passes are often necessary to remove all glass fragments. For carpeted areas, professional cleaning may be required to ensure all microscopic glass particles are removed, especially in homes with young children who play on the floor.

Building a Complete Window Protection Plan

Effective protection from broken glass during storms requires a comprehensive approach. Here’s how to build a complete protection plan for your home:

Assessing Your Specific Risks:

Different properties face different levels of risk based on location, construction, and surrounding environment:

Evaluate your home’s exposure to prevailing storm winds
Identify windows most vulnerable to flying debris (typically those facing large open areas)
Consider nearby trees, structures, or items that could become projectiles
Review your home’s construction era and existing window types
Check local building codes for window protection requirements

What our emergency preparedness experts recommend is creating a prioritized protection plan. If budget constraints prevent protecting all windows, focus first on protecting sleeping areas and designated safe rooms, then address the most vulnerable windows based on direction and exposure.

Creating a Tiered Protection Strategy:

A comprehensive approach often combines multiple protection methods:

Tier 1 (Ideal): Impact-resistant windows or permanent shutters
Tier 2 (Good): Pre-cut storm panels or plywood with permanent mounting hardware
Tier 3 (Basic): Emergency supplies for temporary protection and interior barriers
Tier 4 (Minimal): Designated safe rooms away from windows and personal protective gear

Based on our field testing and experience with different protection systems, we recommend implementing the highest tier your budget allows for your most vulnerable windows, then working down the list for remaining windows. Even partial protection is significantly better than none.

Special Considerations for Different Property Types

Different types of properties require specific approaches to glass protection during storms:

Apartments and Rental Properties:

Renters face unique challenges when protecting windows, as permanent modifications may not be permitted:

Discuss window protection options with your landlord before storm season
Consider tension rod-mounted solutions that don’t require permanent hardware
Focus on interior protection methods and safe room designation
Use removable hooks with fabric barriers as a temporary solution
Keep protective gear and emergency supplies readily accessible

Our specialists emphasize the importance of having this conversation with landlords well before storm season. Many property owners will be receptive to protection methods that don’t damage the building, especially if tenants share some of the cost, as it protects their investment as well.

Historic Homes:

Owners of historic homes must balance protection with preservation concerns:

Consult with historic preservation specialists about appropriate protection methods
Consider custom storm shutters designed to complement historic architecture
Investigate interior-mounted protection systems that don’t alter exterior appearance
Use removable protection methods that won’t damage historic materials
Document historic features thoroughly before installing any protection

In our experience working with owners of historic properties, we’ve found that custom solutions are often necessary. Colonial-style shutters that are both functional and period-appropriate can be an excellent option for historic homes in storm-prone regions.

Financial Considerations and Resources

Window protection represents a significant investment, but various resources can help manage costs:

Insurance Implications:

Installing window protection can have positive insurance implications:

Many insurers offer premium discounts for homes with impact-resistant windows or permanent shutters
Document all window protection improvements and submit to your insurance company
Some states mandate insurance discounts for specific storm mitigation measures
Understand your policy’s coverage for glass breakage and associated damage
Consider separate glass insurance if you have many or large windows

Our team always recommends contacting your insurance provider before making significant investments in window protection. In many cases, the premium reductions over time can offset a substantial portion of the installation costs, especially in high-risk areas where insurance rates are already elevated.

Assistance Programs and Tax Incentives:

Various programs may help offset the cost of window protection:

Check for state or local mitigation grant programs
Look into tax incentives for storm hardening improvements
Some utility companies offer rebates for energy-efficient impact windows
Certain disaster relief organizations provide assistance for vulnerable households
Some manufacturers offer financing options for storm protection products

What our specialists have seen work well is combining different incentive programs. For example, impact-resistant windows often qualify for both storm mitigation and energy efficiency incentives, potentially providing multiple financial benefits for a single improvement.

Conclusion: Creating a Safer Storm Experience

Protecting yourself and your family from broken glass during storms requires thoughtful preparation and appropriate action. By implementing the strategies outlined in this guide, you can significantly reduce the risk of injury and property damage when severe weather strikes.

Remember that no single approach works for everyone—the best protection plan considers your specific situation, including your location’s storm risks, your budget, and your home’s construction. Whether you opt for permanent solutions like impact-resistant windows or focus on emergency preparations and safe room designation, any step toward better protection is valuable.
