Waterproofing is the process of making an object or structure waterproof or water-resistant.
Insulation (thermal insulation) is a general term used to describe products that reduce heat loss or heat gain by providing a barrier between areas that are significantly different in temperature. Buildings themselves need some addittional help to make them more energy efficient. Home insulation therefore reduces the amount of heat that escapes from a building in the winter and protects it from getting too warm in Hot season.
