Insulation Rotorua
Ventilation is the process of bringing fresh air into a building and removing stale or polluted air. In most cases, ventilation is necessary to ensure that people in a building are not exposed to harmful levels of particulate matter (PM), carbon dioxide (CO2), or other pollutants. Insulation is the material that helps to keep a building warm in the winter and cool in the summer.
It does this by slowing down the movement of air and heat through the building. Insulation can be made from a variety of materials, but it is usually made from small, lightweight pieces of paper or cloth that are woven or glued together.
