The word 'insulate' means to protect something or someone from harmful or unwanted outside elements, such as noise, heat, or cold. For example, you might insulate your home with thick walls and windows to keep it warm in the winter and cool in the summer. You can also insulate electrical wires to protect people from electrical shocks. When you insulate something, you create a barrier that keeps things inside safe and comfortable.
