What is "grade"?
When describing the level of your home on which you'll be installing flooring, you'll often hear this referred to as "flooring grade". Typically, rooms that are on the ground floor of the home are considered "on grade". Rooms on any floor above ground level are consider "above grade" and those below (typically a basement) are considered "below grade". It's important to know where you'll be installing the flooring to make sure you choose a product that is suitable for your particular needs. See below for details regarding which floors are best for each grade level.
