Basically, upgrading your insulation will lower your energy consumption, reduce your energy bill, prevent damage caused to your home by moisture, make your home more comfortable and extend the life of your roof.

Ottawa Roofing & Attic Insulation Services - Stewart Roofing

Most home owners don’t give much thought to what’s up in their attics. However, proper insulation is absolutely necessary to ensure your home or building can efficiently stay warm in the winter and cool in the summer. Insulation can help lower energy bills, help prevent mold growth and, depending on the type of insulation use, it can also help reduce noise. The insulation professionals at Stewart Insulation recommend upgrading your attic to at least R50 insulation or the new recommended R60 standard depending on attic capacity. The “R-value” is a measurement of resistance the material has to the movement of heat. The higher the R-value the more effective the insulation. While building codes differ depending on the area and the climate, an R50 – R60 standard attic upgrade is necessary given the often volatile climate swings that can happen in the Ottawa area. With our vast experience as a Certified Owens Corning Preferred Contractor, our team knows that most homes built in the Ottawa area prior to 1995 contain insulation levels that are well below the recommended maximum energy efficiency level of R60, or 22.25 inches of insulation. Those diminished levels can have a significant impact on your seasonal comfort as well as your energy bills. A proper insulation upgrade can change that.

Call Stewart Insulation and our insulation experts can come conduct a full analysis of the state of your residential, commercial or industrial insulation.

We can quickly and efficiently determine the best course of action for you and your budget throughout the entire process. If we discover a situation where your attic insulation has been compromised by moisture, mold or animal feces, Stewart Insulation can quickly remove the contaminated insulation and replace the affected areas with new Propink Blown Fiberglass or Super Pink Fibreglass.
