Impact-Resistant Shutters: Fortified Protection From Damage
Homeowners in storm-prone coastal regions often seek specialized impact-resistant shutters for critical windows to prevent costly damage from extreme weather, flying debris, and wind-driven rain. Unlike ordinary decorative shutters, advanced impact-resistant designs provide formidable multilayered protection able to withstand intense battering. We’ll explore key considerations for impact shutters securing your home.
Meet Stringent Impact Testing Standards
Trustworthy impact-resistant shutters carry designations like Miami-Dade or FBC certifying they’ve passed a recognized large missile impact test. Miami-Dade County’s PA 201, 202, and 203 protocols launch 9-pound 2×4 lumber against shutters at high velocities to simulate debris strikes. Impact shutters must prevent missile penetration, remain intact, and retain operability to earn approval. Impact ratings typically range from basic large missile protection up to enhanced hurricane protection.
Withstand Repeated Bludgeoning Blows
Impact shutters endure hammering strikes and withstand relentless pressure loads exceeding most ordinary building materials’ capacities. Polycarbonate panels, laminated multilayer composites, and steel assemblies are common robust materials engineered for optimal durability under punishing test conditions mimicking storms packing 100+ mph winds.
Exceed Building Code Wind Load Requirements
Impact shutters are overbuilt by design to meet minimum safe facility wind load resistance levels per ASCE 7 standards far surpassing typical vinyl or bahama shutters’ capacities. Miami-Dade protocols test endurance under simulated 3-second 155 mph gusts applied from multiple directions against resisting uplift, lateral, and inward forces. Permitted deformations are strictly limited despite extreme forces.
Guard Against Costly Water Infiltration
Wind-driven rain penetrating cracked or broken architectural openings can cause tremendous damage. Impact shutters’ sealed joints and robust window-mounting systems are designed to prevent water intrusion under torrential downpour conditions post-storm even when structural glazing behind the shutters cracks from pressure differentials. Keeping the interior envelope dry is key.
Deter Accidental Window Impacts
In high-traffic yards or play areas, impact-rated shutters hold up to occasional sports balls, equipment mishaps, and landscape maintenance impacts that might shatter standard glass windows. Their resistance to fracture and denting protects investments in specialty glazing like stained art glass.
Security and Forced Entry Resistance
The same formidable construction that makes impact shutters damage-resistant serves to deter crime and delay burglars attempting to breach locked windows or doors protected by shutters. Cutting through heavy-duty aluminum frames or polycarbonate slats takes extensive effort.
Building Code Compliant
Contractors rely on impact shutters’ third-party product approvals and stringent install guidelines to comply with residential high-velocity hurricane zone building codes. Local municipalities require approved systems on new beachfront construction. Homeowners’ insurance premium discounts provide added incentive.
Long Product Lifespans
Impact-resistant construction withstands the elements over decades of use while maintaining structural integrity. With proper maintenance like re-sealing frame joints occasionally, manufacturers claim service lives of 40-50 years for aluminum and 30+ years for composites. Far longer than normal shutters.
Professional Measurement and Installation
Given their performance-critical nature and complex mounting methods, impact shutters require certified dealer site visits for measurement and experienced installer handling. Follow manufacturer guidelines precisely on approved mounting hardware and anchors. DIY is not advised.
Energy Efficiency Options Available
Some impact shutters like PGT’s ClimateGuard integrate foam insulation, weatherstripping and thermally broken frames to also boost window energy efficiency above code minimums. This saves on utility bills. Impact-rated tinted window and door films layered under shutters also cut solar heat gain.
Enhanced Noise Reduction
With solid metal or multilayered composite construction, impact-resistant shutters upgrade exterior noise control when closed. This helps mitigate road noise and creates pleasantly quiet interior spaces.
While upgrading to fortified impact-resistant shutters represents a sizable investment, the enhanced protection against damage, larger insurance discounts, and security merits consideration by homeowners in vulnerable regions. Their life-safety and loss-prevention value becomes clear once dangerous storms strike. Many consider impact shutters’ cost worthwhile peace of mind.
