Screen doors are hinged doors that have a mesh screen that blocks flying insects and airborne debris, like leaves, from getting into your home. They are also a safety precaution to prevent both children and pets from leaving the premises while the door is open to let in fresh air and take in the view. Screen doors can either be decorative or for security, or a combination of both. Screen doors can be used in conjunction with standard or patio doors.Security Screen Doors
Security screen doors offer an added layer of protection to your home. They often feature very good door locks and lock mechanisms. Most often, the door locking mechanism is a deadbolt that features lever handles and has a single cylinder with a keyhole on both sides. Some doors do have a deadbolt that features a roller catch; these models also often feature standard door knobs. Security doors are often constructed of heavy-duty metal, steel, or wrought iron and many have the option of adding wrought iron or steel bars.Decorative Screen Doors
Decorative screen doors are designed to keep out bugs and debris when you enjoy fresh air and beautiful views. These doors are often constructed of metal and feature a lever handle with or without a lightweight lock. These doors often have a spring attached to the top or the middle of the door that allows you to adjust it, which makes it easier to move items in and out of the doorway.Combination Screen Doors
Combination screen doors are the best of both worlds since they allow for great views and still add an extra layer of security. Most of these doors are enhanced by the use of doorbells. The door is usually constructed of a heavier metal or light steel and features a mid-level security lock. Many of these doors offer a whole screen for better viewing and a layer of glass for cooler weather.Patio Screen Doors
Patio screen doors are large screens that are framed in a light metal similar to your window screens. They are set on a track that runs both on the top and bottom of the frame. Most of these doors feature a sliding lock to keep children from entering or exiting the premises without notice. These patio screen doors are not designed with security in mind, so it is very important to remember to close the glass patio door before leaving your home or going to bed.
