You should consider winterizing your screened porch. This will help keep it protected and allow it to last a longer time. There are a few ways to do this. One option is to install a vinyl film. This helps to convert your porch into an enclosed living area when it is colder by using clear PVC film that is installed in a separate channel from the porch screen. It can cost a bit more, but can help keep the porch safe in winter while allowing you to continue using the space. Some homeowners will consider adding a fireplace, which can be a great investment. There are different cost-effective porch fireplaces that can be used to keep the area warm. You can choose the one that will match up with your style and budget. If you plan on using the area quite a bit in the winter, a combination of a vinyl film and a fireplace can help winterize your screened porch.
