When evaluating insulation materials for home energy efficiency, it is essential to consider factors such as R-value, material type, and installation methods. The R-value indicates the thermal resistance of the insulation; higher R-values suggest better insulation performance. For instance, fiberglass batts typically have an R-value of about 2.9 to 4.3 per inch, while spray foam insulation can achieve R-values of 6 to 7 per inch. This significant difference in R-values helps homeowners understand which materials may offer superior thermal performance.<|im_end|>

Insulation materials vary in how well they keep homes warm or cool. Some are better than others, but it mostly depends on the material. For example, foam is good, and fiberglass is okay too. You just need to put it in the walls and ceilings to do its job. Ultimately, it's about how thick the insulation is, and thicker is usually better, but you don’t need to worry too much about the details.<|im_end|>
