  • Fire resistance: Fire is one of the biggest threats that property owners face - and fireproofing is a good defense against it. We provide an advanced and reliable fireproofing insulation service to protect what you love. In the event of a fire, this service helps by restricting the spread of flames to enable safe evacuation. Fireproofing saves lives and minimizes the damage that can be caused by a fire.

  • Elimination of moisture damage: In addition to its other various advantages, O'Reilly Brothers’ spray foam insulation is moisture resistant. It prevents unwanted air and water from entering into your property, which, in turn avoids moisture from building up. This process reduces the risk of allergens and mould development significantly. All these factors contribute to reducing the costs of fixing the damage caused by moisture buildup.

  • Elimination of leaks: Spray foam insulation service completely blocks out air leaks. It works indefinitely as a rigid barrier against leakage. This saves unnecessary energy costs in two crucial ways. The cold and unwanted air that is blocked by spray foam service would increase heating costs if it were unrestricted, and the release of cold air that would happen otherwise would increase the air conditioning costs.

  • Environment friendly: The insulation services at O'Reilly Brothers help you become a greener citizen and help the environment in several ways. The insulation we install prevents the heat from leaving your home in the winter and keeps it out in the summer while reducing your energy consumption. Moreover, the sprayed polyurethane that we use is safe for the environment. Find out about ‘zero ozone depletion.



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 in 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. Depending on where you live, your home will have insulation of different R-Values. 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, this means that it moves outward in the winter and inward in the summer, depending on the season. Insulation helps in slowing down the movement of heat, reducing the amount of energy required by your heating and cooling system to achieve the optimum temperature, resulting in cost savings for you. Adding insulation to your house is among the most cost-effective methods to save energy, reduce your 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 when it comes to fibreglass, it is better to get help from a contractor for a professional finish.
