Today there are tons of new products derived from recycled and renewable resources that not only help the environment, but can help you save some serious cash. If you want to do more for the planet than just recycle cans and bring reusable grocery bags to the store, consider turning your house into a green project and what better place to start changing to greener alternatives than with the very walls of your own home?

Spray foam insulation is an earth-friendly building material that not only pays for itself but can even produce a healthy profit. It is made from recyclable and renewable materials and is an investment that will make your house more energy efficient and even add value to your property.

Most homes use fiberglass sheets for insulation. These wiry, pink fibers provide minimal climate control and have been known to cause health problems. The sharp material can irritate skin when touched, and loose particles can become caught in the throat, creating scars inside of the esophagus. Although it may seem like a great deal, since fiberglass is cheaper to install than other types of insulation, it comes apart easily, often needing to be partially or fully replaced.

Spray polyurethane foam, commonly referred to as SPF, is a spray-applied insulating foam plastic that is installed as a liquid and then expands many times its original size. It is extremely energy efficient because it easily fills cracks and openings on the surface, making a solid barrier to protect against outside elements.

The tight seal it creates makes it the most energy - efficient insulation available. You won't have to crank up the heater or air conditioner like you have to with fiberglass. And it stays put. You probably will never have to worry about repairs or replacement.

Spray foam insulation also acts as a pest, moisture, and sound repellant. Because it seals so thoroughly, spray foam insulation makes it nearly impossible for insects and other critters to sneak into your home. You'll spend next to nothing on pest control and won't have to fill the air with harmful pesticides.

Likewise moisture doesn't stand a chance against the armor-like spray foam. You won't have to worry about mold, which can destroy your house. And the cushioned walls even easily absorb excess noise, ensuring that you can't hear your neighbors and they can't hear you.

Polyurethane insulation is not only durable, but very versatile. It can be sprayed onto ceilings and floors to add extra protection and insulation. Due to the messy nature of the product, it is highly recommended to have professionals perform the job.

The best way to get green is to start in with your own home, and spray foam insulation is the ideal, environmentally friendly choice. You'll not only improve your home, but you'll help save energy and will contribute to a product that serves to protect the planet. For a small investment, you can save big money over the years with the knowledge that you are contributing to a worthy cause.
