Insulation helps your home hold on to warmth in winter and slow the heat coming in during summer. Small changes behind the walls can make everyday spaces feel better.

Well-chosen insulation can help reduce temperature swings between rooms and throughout the day.
Slowing heat transfer can reduce heating and cooling demand. Actual costs depend on your building, systems and habits.
Pair insulation with appropriate air sealing and ventilation for an approach that considers the whole building.

Insulation can often be improved in existing homes. Access, existing materials and the building’s condition determine what is practical. Attics, accessible framing and some wall cavities may offer options.
Preparation depends on the material and work area. Ask about clearing access, protecting belongings, ventilation and whether occupants or pets need to leave during the work. Confirm a project-specific plan before installation.
Timing depends on the area, access, preparation and chosen material. Confirm the proposed schedule and any re-entry requirements after the scope has been reviewed.
