White window screens are a common choice for homeowners because they are neutral and blend in well with most window frames. They are made of a lightweight, durable material called fiberglass, which is woven into a mesh pattern. The fiberglass screen material allows air to flow through while blocking out insects and other debris. Some white window screens have a plastic or vinyl coating to make them more resistant to fading and damage from the sun. They can be easily removed and replaced when needed, and are a cost-effective way to keep bugs out of your home while allowing natural light and fresh air to come in.
