Moisture and Fire Resistance

I check whether the insulation offers moisture resistance, fire resistance, or both. In my experience, these features matter a lot in basements, attics, and other areas that may face humidity or temperature changes.

Budget and Value

I compare price, coverage, and long-term performance. I do not always choose the cheapest option, because I want insulation that lasts and performs well over time. For me, value means getting good thermal results without overspending.
