A sunroom is typically a fully enclosed structure with large windows or glass panels designed to maximize natural light and extend your indoor living space. Sunrooms can be built as three-season or four-season rooms depending on insulation and climate control.

A porch enclosure converts an existing porch into a protected space using screens, vinyl windows, or glass panels, allowing you to enjoy the outdoors while staying shielded from insects, rain, and wind.
