Spray foam insulation has gained popularity in Canada as an effective method for insulating homes and commercial buildings. However, before making a decision, it’s important to consider the pros and cons to determine if spray foam insulation is worth it for your specific needs.
What are the pros of spray foam insulation?
Improves Energy Efficiency:
Spray foam insulation creates an air tight seal that is the most effective way to reduce air leakage into and from your home. This is one of the most effective ways to combat energy loss and reduce heating and cooling bills. The Ontario Government currently has a grant program for homeowners who want to improve their energy efficiency, and spray foam is highly recommended.
Improves Indoor Comfort
Spray foam insulation improves indoor air quality in two ways. It creates an airtight seal, reducing infiltration of outdoor pollutants, dust and allergens. It also prevents moisture related issues like mold and mildew, creating an environment with safer air quality. When working in conjunction with adequate attic ventilation and a good air exchanger, spray foam creates the best indoor air quality and comfort levels.
Creates a Moisture Barrier:
Spray Foam insulation resists moisture by creating a seamless and impermeable layer, preventing moisture infiltration into the building envelope. This is especially important in areas of high moisture, like basements and crawl spaces. By sealing all gaps and cracks, it prevents damp air from entering the building envelope and causing condensation. By reducing condensation in the building envelope, it reduces the risk of mold and mildew. It is important to deal with any moisture issues prior to installation to ensure effectiveness.
Durable and Long Lasting:
Unlike other methods of insulation, spray foam maintains its integrity and R-value over time. It does not settle or compress, meaning that if undisturbed, spray foam provides a consistent airtight thermal barrier for the lifetime of the building. Its rigidity also adds durability and strength to a buildings structure.
Higher R-Value Per Inch:
Spray foam insulation offers a higher R-value per inch compared to other insulation materials such as fiberglass or cellulose. This means that a much more effective thermal barrier can be fitted into a small space.
It is important to note that all the positive aspects of spray foam depend upon proper installation and superior products. Spray-Tech team offers customers in Ottawa and surrounding areas a superior service by giving them access to insulation specialists, not just insulation installers.
What are the cons of spray foam?
Higher Upfront Cost:
Spray foam insulation is typically three times the cost of alternative methods of insulation. This is due to higher material costs, as well as requiring a certified installer to perform the application. The long-term energy savings as well as improved indoor air quality often outweigh the higher costs.
Installation Complications:
To properly achieve the benefits and avoid issues, installation needs to be done by a certified installer who knows the building science, as well as how to avoid any potential issues. If someone unknowledgeable is installing the spray foam, or the spray foam is an uncertified product, issues such as off ratio spray foam smell and poor performance can occur.
Health Concerns:
During the application process, spray foam releases fumes that are dangerous to our health. Once cured, spray foam is completely harmless. It is important to vacate any premises where spray foam is being installed, as any reputable installer and manufacturer would recommend.
Difficulty to Modify:
Once spray foam is installed it can be difficult to modify wiring or plumbing encased in the foam. It is important to ensure all electrical and plumbing modifications are completed before installation.
Just as achieving the positive aspects of spray foam depend on hiring certified and knowledgeable installers, all the negatives mentioned above can be avoided by doing the same.
