This Summer, Apply Sunscreen Liberally - to Your Home, That Is

This Summer, Apply Sunscreen Liberally - to Your Home, That Is

TOLEDO, Ohio, June 19 /PRNewswire-FirstCall/ -- With warm weather here, it's time to make sure your home is ready for the summer sun's blazing rays. Insulation is like sunscreen for your home, and you need about 19 inches in the attic to protect your home well against summer heat. If you live in one of the 60 million American homes estimated to have under-insulated attics(1), you may want to consider adding some. Taking this step is one of the best ways to reduce your home's energy use for cooling.


"A significant amount of a home's struggle to remain cool is through under-insulated attics, but it's simple to determine if you have enough, and it's easy to add more if you don't," says Gale Tedhams, director of sustainability for Owens Corning. "Go up to your attic. If you can see the wood beams of your attic floor, you don't have enough."

With energy prices skyrocketing, under-insulated homes not only face increased energy costs, they're also emitting one-half ton more greenhouse gas-causing CO2 EVERY year than their properly-insulated neighbors(2).

That's why Owens Corning (NYSE: OC), the makers of PINK insulation, are focused on letting homeowners know about ways to run more energy-efficient homes and do their part to make the planet a little greener. To meet the Department of Energy recommendation for an R-value of up to 60 for attics, Owens Corning advises attics have about 19 inches of fiberglass batt insulation or 22 inches of blown insulation.

"According to a recent global McKinsey study, one of the most cost effective measures to reduce greenhouse gases is building insulation,"(3) says Tedhams. "If we all insulated to the Department of Energy recommendation of R-60, imagine the difference we could make across the nation -- attic by attic, year after year -- in saving money and reducing greenhouse gas emissions."

Owens Corning encourages homeowners to go to, a site where visitors can learn how to save up to 20 percent on their energy bills(4), measure their attic insulation level and find out where to buy insulation.

Homeowners who want to reduce their home's energy footprint should also consider other energy-efficient upgrades such as:

Installing a Programmable Thermostat
Why heat or cool the house when nobody's home? A programmable thermostat can automatically lower or raise a home's air temperature during the day. By regulating the temperature, homeowners can save up to 10 percent on annual heating and cooling costs.

Plugging the Drafts
Sealing the envelope of the home is the first line of defense against drafts, so it's important to caulk and weather-strip around all seams, cracks and openings. Pay special attention to windows and electrical outlets. Unwanted air leakage alone can raise energy bills by up to 10 percent.

Taking a Home Energy Audit
Understanding how much energy a home uses helps homeowners determine what changes will save them the most energy and money. For an easy home energy audit, check out the Home Report Card(R). The quiz provides tailored recommendations for improving home energy efficiency and can be found at
