Entropy Insulation

Entropy Insulation is a local Insulation contractor serving San Antonio, providing attic, wall, and crawl space upgrades with options like spray foam, blown-in cellulose, radiant barriers, and comprehensive air sealing to boost comfort and cut energy costs. Ask for an on-site assessment that includes an attic inspection and air-leakage plan, plus clear R-value targets (often in the R-30 to R-60 range for this climate) so you know exactly what you’re getting and why. Compare material options and request a written quote detailing scope, ventilation strategy, old-insulation removal/cleanup, timeline, and warranty—and ask whether they handle CPS Energy rebates and federal tax credit paperwork. For best results, book before peak summer heat and request a post-install walkthrough or infrared scan to verify coverage and performance.
