Spring is in the Air…and inside?

Spring is in the Air…and inside?

Inside air quality is rarely addressed and tends to be underestimated. Mold and Volatile Organic Compounds (VOC) in homes can cause fatigue, allergies, and respiratory irritation. Finding the source of the problem is part of the solution, or even better, prevention.

Natural airborne bacteria turn into mold when they are exposed to their natural habitat: humidity. Humidity forms over very cold surfaces, or when there isn’t enough airflow in an area. VOC form in furnishing, hygiene products, air fresheners, construction chemicals (paint, glue…), and also generated by combustion (incense, wood, cigarette smoke).

Other than being unhealthy, mold is wholly unaesthetic. Fortunately, it’s easy to recognize: affected areas darken, and often give off an “old, closed” smell. Ti resolve the problem, the first step is to eliminate spores by treating surfaces with an antibacterial product, wash the surface, and then paint the area using mold-resistant products.

This isn’t enough to keep mold away; you have to prevent them from forming based on the original cause. The best way is to identify any areas at risk.

It is best to identify:

  • Cold or humid surfaces, above all, outside walls and walls facing north
  • Humid areas, or places where vapor forms (bathrooms, kitchens, laundry rooms), or where there is little air circulation (corners, angles and walls covered by furnishing)

The best way to isolate cold surfaces where mold forms is thermally. Three ways exist, and all include at lease one layer of thermal material on the existing wall or ceiling (roof):

  • on the external facade
  • on the interior wall (using drywall with a fiberglass and vapor barrier)
  • in the internal wall space, if it exists (with a fiberglass barrier)

If the problem stems from excess air humidity, nothing works better than opening your windows for 30 minutes a day. Lowering air humidity prevents the creation of mold’s favorite habitat.

Ensuring good circulation is a good way to reduce VOC in closed interiors. It is best to eliminate the things that cause them as well; despite the fact that it is difficult to eliminate many of these products, one major way to neutralize VOC is with formaldehyde. There are a series of products integrated into drywall and others materials on the market fit for the job.
