For the optimum in energy efficiency, a home should be well insulated from top to bottom. At the same time, consideration should be given to controlling air movement, moisture collection, and air leakage. A home is a “building envelope”, and as such, requires a “system” approach that is both comprehensive and all-inclusive. Therefore, where to insulate may be a different issue for every home, depending on the building structure and the energy efficiency priorities.
At Great Northern Insulation, in-house experts can propose an insulation approach that will best suit the need, and deliver the best return-on-investment. This will all depend on the part of the home that will be insulated, as well as the product chosen to do the job.
Whatever the product choice, quality insulation in the attic and roof is vital for energy efficiency. In these spaces, R-Value is important to consider, as well as air sealing and good ventilation. Roof leaks and repairs are also part of the project.
In some cases, it’s necessary to seal and insulate exposed ductwork. This will diminish heat loss, which in itself compromises energy efficiency. Where retrofitting is taking place, it would be wise to place and install ductwork strategically.
For homeowners with cathedral ceilings, ensuring appropriate insulation and ventilation are of particular importance, mainly because air movement dynamics. Here again, it’s critical to prevent air leakage, and to stop moisture intrusion.
For homes with walls that feel cold in winter and warm in summer, added insulation may be the right course of action. There are various products and methods for completing this retrofit, each with its own benefits and monetary payoffs.
Beyond additional living comfort, a well-insulated basement saves measurably on energy costs. With a professional installation, heat loss is reduced, moisture accumulation is diminished, and heating/cooling is better regulated.
