Three seasons rooms and dwellings are often not conditioned environments. They will suffer abnormal conditions for interior spaces such as extreme humidity, cold, heat, dry, etc. There are very few flooring options for spaces such as these. Extreme flooring includes specially engineered vinyl tiles and planks which withstand temps as low as -20 and as high as 140 degrees. They are less affected by water vapor (humidity) and dry heat. They do not expand and contract, shift, crack, swell, mold, the way that other hard materials do. Ceramic tile falls into this category as well, as do many carpets and pads. Thus, the three photos of three different unconditioned dwellings/spaces.
