Natural slate is a warm and inviting choice for interior flooring. Though it must be sealed, the material is resistant to fading, scratches and chemicals. The wide variety of color options from light tan to deep black make the tiles quite versatile. For a recent sunroom interior design project, we chose to play with a mix of colors. The lighter tones blended well with the open and airy nature of the room, and the texture and movement within the tiles added visual interest.
