What's the Best Insulation for Indoor Air Quality?


On a national average, Canadians spend as much as 90 percent of their time indoors. Whether it's at home, in an office, at school, or at college, this means that most of the air you're breathing on a daily basis is indoor air.

While indoor air quality might not even occur to most of us, it makes a huge difference to your overall and long-term health.

If you're thinking of re-insulating your home, here's why you should opt for spray foam insulation if indoor air quality is a priority to you.

What Is Spray Foam Insulation?

This is one of the best materials on the market today for insulating your home due to an array of factors. The most important of which, for many homeowners, is how it can improve your indoor air quality.

Also known as SPF, it's a material made out of two key chemicals: isocyanate and polyol resin. This product made its way to the market in 1986 but has since become a popular form of insulation for many modern-day homes.

Spray foam is ideal for creating a brilliant insulation barrier. It seals floors, ceilings, walls, around windows and doors, and even the spaces between fixtures and electrical outlets.

Today, it's often sprayed into open cavities in both new and older homes, such as attics, rim joists, and crawl spaces.

Unlike other insulation materials, spray foam is exceptionally adaptable and will never lose the shape it forms, meaning it won't sag, settle, or compress. This means it's one of the best materials for filling cracks, gaps, and open spaces.

Why Choose Spray Foam for Better Indoor Air Quality?

Despite the fact that it's comprised of chemicals, don't let that fool you into thinking spray foam can contaminate your indoor air.

Once expanded and fully formed, spray foam does not dissipate or emit fumes or fibres, unlike other home insulation materials. Here are a few other key reasons why it's great for indoor air quality:

  • Spray foam blocks water vapour from entering your home, solving moisture problems such as dampness and mould

  • Spray foam keeps your home airtight, limiting outdoor pollution from entering your space

  • It does not emit harmful toxins, fumes, or fibres that can flare up or exacerbate allergies

  • This material also prevents the accumulation of dust particles that enter your home, naturally keeping your indoor air clean and allergen-free

If you choose spray foam as a form of insulation, just keep in mind that you should always choose professional installation. This is not a recommended DIY project.

You'll need to do some research on local contractors who have the right amount of experience, training, licensure, and insurance to install spray foam. Yes, there are other forms of insulation you could install yourself, such as cotton and cellulose. But they do not offer the same benefits for your home's indoor air quality.
