Conserving with Curtains

One of the least expensive ways to regulate temperature in your home is to invest in curtains. Curtains help to keep heat out, or lock it in, depending on the time of year. By you taking the proper approach to curtains, your AC or heater can avoid working harder than it needs to. Heat loss and heat gain directly affect the cost of your energy bill. Practice energy efficiency and reduce your energy bill with curtains.

Reject the Heat in Summer

Curtains help keep your home cool during the summer by rejecting the heat from outside. To help keep the heat out, it’s not a bad idea to invest in a light-colored curtain. Lighter colors reflect sunlight as opposed to absorbing it like darker colors do. Selecting a light drape with a solar backing will make an optimal barrier to prevent sunlight from passing through into your home. A light drape will also allow for partial lighting inside so you don’t have to turn on the lights.

Keep Heat in Winter

During the winter, keep those curtains open. This allows for sunlight to pass through into your home, potentially lessening the need to use the heater. Once the sun sets, close the curtains to lock heat inside the house at night. The DOE suggests closing curtains at night could potentially save you up to 10% in heat loss. That’s a lot of heat and a lot of money!

Styles

There are a few different approaches you can take to curtains to help keep your home energy and cost effective.

  • Energy Efficient: Energy efficient curtains typically have a spongy thermal lining that helps prevent heat from passing through. Energy efficient curtains can be made separate from drapes, so if you already have your own set of drapes or curtains, you can just get the lining.
  • Layers: Combining several layers of curtains will help provide insulation. With layers, we recommend adding one light outer curtain and one dark inner curtain to allow for sunlight during the day and privacy at night. The still air between your room side curtain and the one closest to the window improves insulation.
  • Quilts: A strange but effective concept, the quilt is a slight variation of the curtain, consisting of an insulating layer and a vapor barrier surrounded by cloth fabric, which helps keep moisture from absorbing in the quilt.
