Installing double glazed windows, cavity wall insulation, loft insulation, draught exclusion around doors and windows, and carpeting can help reduce energy losses from a home. This leads to advantages like using less fuel to heat the home, lower heating bills, conservation of energy sources, and less pollution. Double glazing can reduce energy passing through windows by 50% compared to single glazed windows. Filling cavity walls with insulation and insulating the loft helps prevent heat from escaping through exterior walls and upstairs ceilings.
