Which way do you lay insulation?

When laying insulation, it should be installed with the paper or foil facing the warm side of the building, which helps to prevent moisture buildup. In attics, insulation is typically placed between the rafters, while in walls and floors, it fits snugly between the studs or joists. It’s important to avoid compressing the insulation, as this can reduce its effectiveness. Ensure that the insulation is installed without gaps or overlaps for optimal thermal performance.
