Here's a great video on how to close in your porch for the winter.
Many people purchase plastic that can be used to cover the screens on the porch. You can nail or staple . They also use this type plastic to cover windows during cold weather. Check with hardware stores, Lowes, Home Depot, Ace, etc. Good luck
Make frames to fit is each opening. Seal each frame [so the Winter weather does not degrade it]. Purchase heavy duty plastic. Attach this plastic to the frames. Put each unit into each space. Remove and store for next year.
