What Are the Pros and Cons of Window Screens?
The benefits of window screens include protection and curb appeal. Downsides mostly have to do with costs.
The Benefits of Window Screen Installation
The primary function of window screens in most cases is to support airflow while blocking entry to unwanted pests and debris. A quality window screen creates a barrier for insect protection and pest control, letting you open windows for natural ventilation without worrying about flies or other things finding their way inside.
Other benefits include:
Reduced allergens and debris: Screens keep large debris like leaves from blowing into your home, and some options include allergen filtration that traps dust and pollen.
Decreased AC use: Opening windows to let in fresh air when it's mild out can increase indoor air quality while supporting energy efficiency for your home. Many times, allowing a cool breeze to blow through your home lets you avoid turning on the AC.
Safety for children and pets: The right screens can provide a barrier that helps keep children and pets safe when windows are open.
Additional curb appeal: Some people think windows look better with high-quality screens, enhancing curb appeal for a home. Windows designed for screens may look "naked" to some people without them.
Some screens offer unique benefits. Security screens, for example, offer storm damage protection and make it more difficult for individuals to break into a home via the windows.
The Downsides of Window Screens
The biggest downside to installing window screens for most homeowners is the cost. Window screen installation or replacement cost can run $100 to $350 (CAD 137 to CAD 481) per window, depending on the size of the window and what type of screen features are important to you.
Other potential cons of window screens include:
Less natural light: Screens can reduce how much light comes in your windows, which may not make them ideal for areas where you want to grow plants or use natural light for reading.
Obstructed window views: The metal mesh of the screen can restrict the clarity of your outdoor view, making screens less desirable when you have a room with a great mountain or coastal view.
The need for cleaning and maintenance: Screens can trap debris and moisture, requiring additional seasonal window maintenance to keep the surrounding area clean and in good condition.
While safety screens, which bolt into windows, can help keep kids and dogs safe, screens that pop out can be a hazard. They can create a visual sense of safety that encourages children and animals to lean into them, increasing fall risks.
