Badly Insulated Attic: Paradise for Mold!

The attics play an important role in energy efficiency and residential well-being. However, inadequate attic insulation can lead to serious problems that make the house uncomfortable. In this article, we will explore mold, which is one of these difficulties, with harmful consequences for the home, and discuss measures to remedy and prevent it.

Why is there mold in the attic?

Molds thrive in damp and poorly ventilated spaces; it's the perfect ground for their proliferation. Poor attic insulation creates these perfect conditions.

And what does "poor insulation" mean?

Many people forget a crucial step before installing the insulation in the attic which is sealing all sources of air leaks. Neglecting this step allows warm and humid air to infiltrate the attic. This causes a dual problem: On one side, it strengthens mold growth conditions. On the other side, it counteracts the existing insulation, thereby reducing its effectiveness.

And what are the sources of air leaks?

- Holes for electrical wires and pipes.

- Recessed lights.

- Ventilation ducts.

- Attic access hatch.

- Space around the chimney.

Consequences?

The presence of mold in the attic can have serious consequences for the residents' health as well as for the house itself:

Residents' health?

Exposure to mold leads to:

- Respiratory problems (asthma attacks, difficulty breathing, coughing).

- Allergic reactions (sneezing, itchy eyes, rashes, etc.).

- Increased risk of heart problems.

- Moreover, some molds produce toxic substances that can have long-term adverse effects on health.

House's Well-being?

Molds can cause structural damage to the house such as:

- Deterioration of the quality of attic walls, weakening the roof structure.

- Degradation of the quality of existing insulation.

- Spread of a bad smell and indoor air quality that may damage certain furniture.

Solution?

To prevent mold growth in the attic, it is essential to maintain adequate insulation, which involves:

- Locating and sealing all air leaks in the attic to prevent air movement.

- Ensuring that the insulation is in good condition and applying a suitable amount to achieve the recommended "R" thermal value.

If there are already mold stains, it is necessary to get rid of them before completing the insulation steps mentioned above. For this, there are several products. We can mention:

- Mold-X2 Stain Remover, used to clean contaminated surfaces usually made of bare wood or drywall. Applying this product eliminates dark stains and discoloration caused by mold to restore the surface to its original appearance.

- Mold-X2 Botanical Antimicrobial, used to prevent the recurrence of mold. This treatment makes the surface resistant to mold without posing a danger to humans or animals.

Remember that consulting with a professional is always necessary to assess the condition of your attic and recommend the best solutions to maintain a healthy environment in your home.
