How Insulation Works

Insulation works and is very interesting! Not only does it help make your home warmer in the winter, but it also helps keep it cool in the summer.

Heat flows naturally from a warmer to a cooler space. In winter, the heat moves directly from all heated living spaces to the outdoors and to adjacent unheated attics, garages, and basements – wherever there is a difference in temperature. During the summer, heat moves from outdoors to the house interior. To maintain comfort, the heat lost in winter must be replaced by your heating system and the heat gained in summer must be removed by your air conditioner. Insulating ceilings, walls, and floors decreases the heating or cooling needed by providing an effective resistance to the flow of heat.

So how does insulation work?

It’s sometimes difficult to understand how insulation works to keep your home warm. Think of an insulated flask or Thermos which helps keep your drinks hot or cold. This works by providing an insulated later between the drink and the outside air. Insulating your home has the same effect helping to keep your inside conditions comfortable all year round.

Uninsulated homes have large gaps or cavities between exterior of your house and your inside walls. By filling these cavities with an insulating material, the outside air can’t pass through the cavity as easily and it prevents the inside air escaping outside. Insulation installed at a high density with no gaps  also reduces internal wall convection. The insulation acts as a barrier to the flow of heat. It keeps the heat contained when it’s cold and keeps it out when it’s warm.
