A sunroom is a structure constructed onto a home that allows for the enjoyment of the surrounding scenery while being protected from inclement weather. This sunroom structure is also often referred to as a solarium, patio room, patio enclosure, conservatory, or Florida room. While many of these terms can be used interchangeably to describe a glassed in home addition that provides an open, light and relaxing space, the words Sunroom and Solarium do define different structures. But what is the difference between the two? Which one will be best for your home? The key differences between a sunroom vs a solarium is its intended use, the pros & cons of each, the required maintenance, and the resale value on your investment.
