Rock Lake homeowners face a critical decision when planning skylight renovations: modern glass or traditional plastic domes. Glass skylights deliver superior durability and energy efficiency but cost more upfront. Plastic domes offer budget-friendly installation but sacrifice long-term performance. This guide breaks down the key differences to help you make the right choice for your Orlando home.
Glass skylights feature tempered or laminated impact-resistant glass that withstands Florida’s hurricane-force winds and flying debris. They include argon gas insulation and Low-E coatings that block UV rays while maintaining indoor temperatures. Plastic domes use acrylic or polycarbonate materials that yellow and crack over time from UV exposure. While cheaper initially, they require replacement every 10-15 years compared to 20-30 years for quality glass units. Florida Building Code compliance.
Energy efficiency separates these options dramatically. Glass skylights with proper glazing achieve Solar Heat Gain Coefficients of 0.25 or lower, keeping Orlando’s summer heat outside. Plastic domes typically have SHGC values above 0.50, allowing excessive heat transfer that increases cooling costs. The U-factor insulation rating for glass ranges from 0.30 to 0.50, while plastic domes often exceed 1.00. Is Solar Roofing Actually Worth the Investment for Orlando Residents?.
