Most modern walls are as thin as the insulation allows. Ours are often thicker, and the windows sit deep inside them.

What a deep reveal does

  • Shades the glass from high summer sun
  • Lets low winter sun reach far into the room
  • Frames the view like a picture
  • Gives you a seat, a shelf or a desk
