Local Factors
Key Biscayne, being located within Miami-Dade County, falls under strict building codes, particularly concerning hurricane protection. You’re in a High Velocity Hurricane Zone (HVHZ), so impact windows are essentially mandatory for most properties. This means your windows need to withstand high winds and windborne debris. Expect to obtain permits from the Miami-Dade County Permitting Department before starting any window replacement project. Your contractor will typically handle this, but it’s good to be aware of the process.
Installation labor rates in the Key Biscayne area are higher than the national average due to the specialized skills required for impact window installation and the overall cost of living. Expect to pay a premium for experienced and licensed installers. A licensed contractor (verified via DBPR License Search) is crucial to ensure proper installation and code compliance. Incorrectly installed impact windows can compromise their effectiveness and even void warranties.
Weather Impact
Key Biscayne’s climate presents several challenges for windows. The high humidity can cause mold and mildew growth, which is why vinyl or aluminum frames are popular choices as they are resistant to moisture damage. Intense UV rays from the Florida sun can fade fabrics and damage interior furnishings. Therefore, opting for Low-E 366 glass is highly recommended. This type of glass blocks a significant portion of the sun’s harmful UV rays, helping to keep your home cooler and protect your belongings.
Of course, hurricane protection is paramount. Laminated glass is a key component of impact windows. It consists of two or more layers of glass bonded together with a plastic interlayer. This interlayer prevents the glass from shattering upon impact, protecting your home from wind and water damage during a storm.
