The best type of attic insulation depends on where you live, your budget, and what stage of construction the attic is in. For example, if you're building a house, then structural insulated panels are a worthy investment since they're easy to install during construction and they're the most energy-efficient type of insulation.

Additionally, if you live in a very warm climate, then you can potentially save quite a bit of money by opting for reflective insulation, which is more affordable than comprehensive insulation but doesn't work well for cool climates. Blown-in, loose-fill, and spray foam insulation are all great options for attics in moderate climates.

Insulating your home's exterior walls can realize up to a 20% reduction in your monthly energy bills. This means that regardless of how much the project costs, it can begin to pay you back immediately. Additionally, adding spray foam and other high-end materials can increase the selling value of the property.
