You may think having no insulation is not a problem but the temperature in your home has a lot to do with it. This home had really old insulation that was no longer beneficial to the home. The crew removed all of old insulation, and vacuumed all of the debris up. After this they sanitized to kill 99.9% of viruses, odors, and bacteria. Then they rodent proofed sealing all entry points that rodents might have access to. Finally the attic is ready for insulation, they installed brand new Owen’s Corning Ecotouch R-30 batts insulation.
