Should I get impact windows or hurricane shutters in Broward County?
The decision depends on your priorities and budget. Impact windows cost $800-1,500 per window installed vs $200-400 for shutters per opening. However, impact windows provide 24/7 protection without deployment, 15-30% insurance discounts (vs 8-15% for shutters), 25% energy savings, noise reduction, and increased property value. Over 10 years, impact windows often cost less when factoring insurance savings, energy efficiency, and eliminating shutter maintenance. Shutters win for tight budgets or rental properties.
What insurance discount can I get for impact windows in Broward County?
Impact windows in Broward County typically qualify for 15-30% wind mitigation discounts on homeowner's insurance. The exact discount depends on your insurer and policy, but averages $800-2,500 annually for a typical home. To receive the maximum discount, you need a wind mitigation inspection (Form OIR-B1-1802) documenting that ALL openings have impact-rated protection. Partial coverage (mixing impact windows with shutters on some openings) reduces the discount proportionally.
How much do impact windows cost in Broward County?
Impact window costs in Broward County range from $800-1,500 per window installed for standard sizes, varying by frame material: vinyl frames $800-1,000, aluminum frames $900-1,200, and fiberglass frames $1,200-1,500. Large picture windows or custom sizes can reach $2,000-4,000 each. A typical 2,500 sq ft home with 15-20 windows averages $15,000-30,000 for complete replacement. HVHZ areas (east Broward near the coast) require higher-rated windows that cost approximately 10-20% more than non-HVHZ zones.
What DP rating do impact windows need in Broward County?
Impact window DP ratings in Broward County depend on your zone. HVHZ areas (generally east of I-95) typically require DP +50 to +80 with large missile impact certification. Non-HVHZ areas (western Broward) typically require DP +35 to +55 with small missile impact certification. Corner zones, upper floors, and direct coastal exposure can increase requirements by 15-25%. Your wind load calculation determines the exact DP needed for each window based on its specific size, height, and location on the building.
Do impact windows eliminate the need for hurricane shutters?
Yes, properly rated impact windows completely eliminate the need for additional hurricane shutters. Impact windows are tested to the same rigorous standards as shutters - including large missile impact testing (9 lb 2x4 lumber at 50 fps in HVHZ zones) and cyclic pressure testing per ASTM E1996/E1886. The key is ensuring your impact windows meet or exceed the required DP rating for each specific opening. A wind load calculation confirms your windows meet code requirements without any supplemental protection.
How do impact windows reduce energy costs?
Impact windows reduce energy costs through multiple mechanisms: 1) Low-E coatings reflect infrared heat while allowing visible light, reducing AC load by 25-30%, 2) Laminated glass blocks 99% of UV rays that heat interiors, 3) Better seals eliminate air infiltration that wastes conditioned air, 4) Argon gas fills between panes add insulation. In Broward County's climate, these improvements typically save $400-800 annually on cooling costs. The energy savings compound over time and help offset the higher initial investment.
