These types of insulation are best in extremely cold climates, but they’re generally preferred for new construction, as they can be challenging to retrofit.

It’s important to choose an insulation type that meets your needs based on climate, as maximizing R-value may not always be financially worthwhile if you live in a moderate climate.
