I recently had my attic insulated by a company, and I wasn't completely satisfied with the results. The technicians did an average job, but I expected better insulation. The temperature inside my house didn't change much, and my energy bills remained high. I decided to try Spray Foam Insulation based on recommendations, and they did a slightly better job. However, I still feel that the insulation could have been improved further. It was an average experience overall.
