Frequently asked question about roof and attic insulation in Quebec

What’s the use of styrovents in addition of blown wool?

The styrovents ensure good air circulation in your roof space. They are necessary to ensure effectiveness when adding cellulose.

Does blown wool take a long time to install?

The installation of blown wool is a relatively quick process. For a house of 1,000 ft2 for example, one or two hours are enough to perform the work.


How does blown wool help me with icicle formation in my gutters?

Heat loss due to insufficient insulation is responsible for the formation of ice. Adding a sufficient amount of blown wool in your entire roof space will minimize heat loss and therefore eliminate the formation of icicles.


How can the addition of cellulose fix my condensation problem?

Most of the time, a condensation problem is due to poor ventilation in the attic. Installing styrovents before adding cellulose will play a key role in reducing the humidity in your home to a minimum. Installing a ceiling fan is also recommended and it can be necessary in some cases to clear the soffits, our team can help you with this.
