This section features some commonly asked questions regarding insulation and our services. Continue reading. You may have similar concerns. If your question does not appear on our list, call us. Our team has the most up-to-date, reliable information.

  • Which type of insulation do I need? - The type of insulation depends on where it needs to be installed. For instance, a home in Edmonton will have a different R-Value requirement than where it needs to be installed both in the home and the home’s location.

  • What is R-Value? - “R” stands for resistance to heat flow. The higher the R-Value, the greater the insulating power. Your home will have insulation of different R-Values depending on where you live. For example, a colder climate requires a higher value than a milder one.

  • How does insulation work? - When it comes to insulation, it works by preventing the movement of heat. Heat is a source of energy that constantly seeks a colder environment. In your house, it moves outward in the winter and inward in the summer, depending on the season. Insulation helps slow the movement of heat, reducing the energy required by your heating and cooling system to achieve the optimum temperature, resulting in cost savings. Adding insulation to your house is among the most cost-effective methods to save energy, reduce heating and cooling expenses, and make your home more comfortable.

  • Do the foundation's external walls need to be insulated when building a new house? - If you reside in a location prone to heavy snowfall and freezing conditions, you can add spray foam to the inside of the exterior walls.

  • Can I do the insulation myself? - Fibreglass batts are easy to install, but some projects like loose-fill or blown-in insulation require specialized air equipment. That's why the services of an insulation contractor are needed. Even with fibreglass, getting help from a contractor for a professional finish is better.
