Although spray foam insulation has been around for decades, it is just recently becoming more popular, thanks to an increased interest in building energy-efficient homes. It's true that spray foam can reduce energy consumption with its superior insulating ability and knack for sealing up leaky cracks. However, not all of the information that gets tossed around about spray foam is true. Here's a look at three truths and a lie about spray foam insulation.

Truth: Spray foam insulation is a good choice for people with allergens.

Spray foam insulation is resistant to moisture and does not trap dust and mold particles like fiberglass and cotton insulation often do, according to the American Chemistry Council. It also keeps these particles from blowing into the home through cracks. Thus, many people experience a reduction in allergy symptoms when they replace their traditional insulation with spray foam.

Truth: Spray foam is a good choice for homes in hot or cold climates.

It's a common misconception that only homes in areas where the winters are super-cold need spray foam. However, this material is also great for keeping homes in hot areas cool. It can lead to a reduction in air conditioning bills in the summer.

Truth: Spray foam can extend the life of older buildings.

Since it becomes solid once it's sprayed, it can make older buildings more structurally sound by adding support to the walls. Spray foam is actually one of the only insulation materials that can be used in some historic buildings with very small wall spaces, since it can be applied through a small hole without taking down a whole wall.

Lie: Spray foam is simple to apply.

To the inexperience observer, it may seem like all a spray foam applicator needs to do is aim and pull the trigger. However, there is a lot of science behind determining how to apply spray foam to a certain building. The wrong mixture of chemicals, applying when the temperature is too hot, or spraying a layer that's too thick or too thin may lead to serious problems. To avoid having your insulation peel away from your walls, stay too soft, or allow leaks, always hire a professional applicator with plenty of experience and a certification to apply your spray foam.

Choosing spray foam insulation over traditional fiberglass batt insulation is a move that is great for your energy bills and for your wallet. Don't be afraid of the naysayers that think it's only for cold climates. Hire a trusted applicator, and you can start enjoying the benefits within a few days.
