Mould: More Than a Cosmetic Problem – A Health Hazard!

"Mould" refers to microscopic fungi, usually black or white, that is sometimes found on food and moist surfaces.

Moisture is the main factor that causes mould to grow and spread. Mould releases into the air reproductive cells called "spores" that are so small you can inhale them. Breathing in large amounts of these spores can have a negative impact on your health.

Insulating against mould

  • Outside
    • To prevent mould from growing, you need to protect your home against the following types of infiltration:
      • Water
      • Air

To do this, an exterior air barrier – properly installed and sealed — is highly recommended.

  • Inside
    • Your goal is to avoid condensation on the inside of the walls. For this, we recommend:
      • Installing a vapor barrier that is well in place and sealed
      • Eliminating air pockets between the insulation and the foundation wall substrate (cement) to avoid the risk of condensation and mould

Main health problems due to mould

There is a link between the degree of humidity inside a house, the presence of mould and health problems, such as:

  • Eye, nose, and throat irritations
  • Coughing (phlegm)
  • Shortness of breath and wheezing
  • Asthma
  • Allergic reactions

Certain groups of people – mainly children and the elderly – are more vulnerable than others to mould.

If you think that mould could be affecting you or your family’s health, consult a professional at your health centre.
