Spray foam has the highest R-value and air-sealing properties but costs 3–5x more than fiberglass batt. Blown-in cellulose or fiberglass is the most cost-effective for attics. The best choice depends on location (attic vs. walls vs. crawl space).
Adding insulation without structural changes typically doesn't require a permit. Spray foam applications may require ventilation inspections in some jurisdictions. Adding insulation to a new conditioned space (finishing a basement) usually requires a permit.
