Summertime and the livin’ is easy. Until you get your first summer cooling bill. Americans spend about $29 billion on air conditioning every year. But you’ve got better things to do with your money — like going on vacation.

While many people think about insulating for the winter, somehow they forget its importance for the summer. Maybe they think insulation is like putting on a coat. But here’s the deal: warm air always moves toward cooler air. So in the winter, heated air tries to get outside into the cold. And in the summer, hot air wants to get into your nice, cool house. All year long, the thing in between is insulation.

That’s why it’s so important to have enough insulation. And here’s where cellulose insulation makes a big difference because 1) it’s dense and 2) it can be blown into every little space where air could infiltrate. The result is that cellulose could help you save up to 25 percent on your energy bill.¹

Cellulose has other advantages, too, like reducing noise by absorbing 90 percent of sounds² and resisting fire 57 percent better than other types of insulation.³

On top of all that — literally —it can easily be blown in over old insulation in your attic to reach the R-value needed to increase your home’s energy efficiency. Or, it’s perfect for new construction since it’s easy to install and makes sure to fill every void.   

If you’re installing blow-in cellulose yourself, you won’t sweat that anymore than your energy bills. It’s easy to do with a blower machine, which is usually available to rent from the same place you buy Greenfiber.
