Spring is a key time for examining your insulation for two reasons.

  1. It’s a time of milder weather that lends itself to making any necessary adjustments to your insulation between the harsh winter temperatures and a sweltering summer heat.
  2. It’s a prime time for allergies, and your insulation may be contributing to your seasonal and indoor allergies.


If you’ve ever touched fiberglass batting, you’ve likely experienced the itchy redness it causes when it comes in contact with your skin. Unpleasant is an understatement. When ductwork is damaged or improperly sealed, particles of fiberglass can make their way through the vents in your home, causing skin, eye, and respiratory irritation.


Blown-in insulation that uses recycled newspaper or cut up denim tends to create more dust that will find its way into the home in a variety of ways. (Note: if you’re blowing insulation into a home with allergy sufferers, it’s best that the allergy sufferers not be present during the process.) In addition to the dust, some of these materials also contain chemicals that trigger allergic responses. Imagine living in a home in which an allergen fills your walls and attic. Miserable!

The best insulation for allergies: spray foam

Spray foam insulation is a better option in the homes of allergy sufferers for multiple reasons.

First of all, the material does not lend itself to producing dust particles of any kind. Once the foam has expanded and solidified it doesn’t collect pest remains, dust mites, rodent droppings, or any other debris found in other types of insulation. All of those things are known allergy triggers.

Secondly, spray foam insulation seals leaks other insulations miss. This means that what happens in the attic stays in the attic. There won’t be any dust mites or pests that make their way through the ductwork and into your home. You may not be able to eradicate all the weeds, trees, and grasses that make you sneeze, but keeping those pollens on the outside makes it possible to have an allergy respite inside. You’re effectively keeping more allergens out with spray foam insulation (and a good air filter), improving your indoor air quality.

Finally, this type of insulation is the greener option. It doesn’t settle over time like batts that need to be reinforced on occasion. Because it seals air leaks so well, it also conserves energy usage in your home. Fewer carbon emissions in the air means the air you breathe outside you home is healthier, too.
