Insulating sunroom floor
Bought a house 2 years ago. The sunroom has a 3-4ft tall crawl space under it. Its essentially built on a deck. The previous owners said they intended to insulate the floor underneath.
Im curious what impact that would really have? The entire room is glass sliding doors and windows. It gets cold in the winter until the sun hits it and it warms up a bit. Definitely a 3 season room. What benefits woukd insulting the floor provide?
