House insulation: the most effective insulation so having in mind that spray foam, fiberglass, and cellulose are the three mostly used insulation materials we made a comparison, and here are the results: spray foam has by far the highest r-value, which is crucial for homes in extremely cold climates. Overall, fibreglass insulation is the cheapest and most effective insulation option available, making it a popular choice for homeowners and builders alike.Spray Foam Insulation: Offers the highest R-value (~R-6. R-6. It’s ideal for irregular spaces and maximizing energy savings. Fiberglass Insulation: Affordable, widely available, and easy to install.
What is the longest lasting insulation?

Mineral wool can also last up to 100 years if properly installed and maintained. Foam board insulation, including types such as polystyrene, polyisocyanurate, and polyurethane, has a lifespan of 30 to 50 years. This type of insulation stands out for its moisture resistance and high thermal resistance, which contribute to its longevity and effectiveness in various applications.
