When selecting impact windows for your South Florida home, one of the first choices you will face is between single hung and double hung window styles. Both provide the essential hurricane protection you need, but they differ in how they operate, what they cost, and how easy they are to maintain. From our years in the field, understanding these differences will help you make the best decision for each room in your home.
Single hung windows have a fixed upper sash and a lower sash that slides vertically to open. This simpler design means fewer moving parts, which translates to a lower purchase price and reduced long-term maintenance needs. Single hung impact windows are the most popular choice in South Florida for bedrooms, living rooms, and other standard applications. Their streamlined mechanism also provides a slightly better seal against air and water infiltration since only one sash has operable weatherstripping that can wear over time.
Double hung windows allow both the upper and lower sashes to move independently. This dual operation provides superior ventilation options, as you can open the top sash to let hot air escape while cool air enters through the bottom. Many double hung impact windows also feature tilt-in sashes that allow you to clean the exterior glass from inside your home, a valuable convenience for upper-story windows in multi-level South Florida homes. This added functionality comes at a modest price premium over single hung models.
For most South Florida homes, a combination of both styles works best. Use single hung impact windows in areas where basic ventilation is sufficient and budget is a consideration, such as bedrooms and hallways. Choose double hung impact windows for kitchens, bathrooms, and upper floors where enhanced airflow and easy cleaning access are particularly valuable. Both styles are available in a wide range of frame colors and grid patterns to match any architectural style found throughout South Florida.
