Insulation in San Antonio: what to know
With cooling running most of the year, attic insulation does heavy lifting in San Antonio, where attic temperatures soar and older Alamo Heights homes often have thin or compressed coverage. Blown-in top-ups paired with air sealing around ducts and light fixtures are common requests. Spring and fall are the most comfortable times for attic work, and larger projects may require a permit depending on scope.
