Insulation improvements refer to enhancements made to the materials and techniques used to reduce heat transfer in buildings. This can involve upgrading existing insulation in walls, attics, and floors, or using more effective materials like spray foam, fiberglass, or cellulose. Better insulation helps maintain comfortable indoor temperatures and can lead to lower energy bills. These improvements also contribute to energy efficiency and environmental sustainability. By reducing the amount of energy needed for heating and cooling, buildings can decrease their carbon footprint. Additionally, improved insulation can enhance indoor air quality by minimizing drafts and moisture buildup, creating a healthier living environment.
