Is Spray Foam Insulation the Best Choice?

Adding spray foam insulation to your new home or addition offers you the highest R values per inch you can buy to block moisture and heat escape. In comparison to blown-in fiberglass insulation with an R-value of R2 or R3, certain types of spray foam products offer R5 or R6,
which indicates an improved ability to prevent heat from moving through it. While this product is more expensive than other insulation products, it can be 50% more effective than traditional products; the monthly energy-savings can completely offset the initial installation cost.

Does this make this type of insulation the best product for your home?

How is Sprayed Foam Insulation Different from Other Types?

Spray foam is made of polyurethane, and it is applied by mixing two chemical compounds on the spot. A certified installer aims a hose with Side A chemicals that start the reaction that creates polymer chains that comprise the product with Side B oils and oil derivatives, including plastic material, flame retardants, catalysts, surfactants, and water or blowing agents, which bond and form the plastic material. The hoses are calibrated to stay "on ratio" so that they dispense the proper amount of each material.

To make sure the installation procedure is done correctly, you need an experienced installer who carefully monitors the equipment and environmental conditions for best results. The product, which takes 24 hours to cure, is best installed in warmer, dry conditions.

There are two types of spray foam insulation:

• Open cell products, which can be crushed in your hand, offer lower insulation values and lack a water vapor barrier, which makes it an ideal choice for interior walls. This product has good soundproofing qualities.
• Closed cell products, which are rigid to the touch, block air and water, which makes them a good choice for interior walls, roofing projects, or outdoor applications. Inorganic in nature, they prevent mold growth and repel pests and humidity. You will need less heat and air-conditioning with closed cell products.

Is it Safe for Installation in Your Home?

The product has come under fire from environmentalists because it is made from fossil fuels, and because it contains chemicals that can have long-lasting health effects. Current formulations now only have trace amounts of formaldehyde, and most off-gassing of current formulations occurs within the 24 hour curing period.

Choose Spray Foam for Unbeatable Insulating Properties

Spray foam insulation is undoubtedly the best choice for keeping energy costs in line in a new home or in an addition to your existing home. When properly installed, spray foam keeps your warm or cold air inside the home where you want it. Because less escapes, you effectively pay for the level of heating or cooling you want and need, not what is lost.
