Replacing Windows in Sunroom
I am helping my parents replace Pella (wood) windows that are 18 years old and they have rotted pretty bad. They need to be replaced, but my question is with what type and brand. This is a sunroom where we keep plants during the winter months, so I know that moisture is a problem. We would like to keep this room as a sunroom for plants, but what type of windows should we use to replace the old ones with? Based on what I have learned, vinyl windows might be an option. Any suggestions?
