If you live in a hot climate, close your drapes and blinds to keep the hot sun out to save on energy costs. Your air will come on less and you’ll reduce your electricity bills considerably. While any drapery can help, insulated drapes or blinds are best for providing that thermal shield. Even multiple layers can offer some energy-saving benefit.
When it’s cold outside, you can also help to reduce drafts with the same drapes and blinds. Remember to measure the width as well as the length properly when shopping for insulated draperies. And if you want to have them a long time, choose a neutral color that blends in well with your decor.
