It is possible to lower energy consumption and heating bills by installing insulation. The building block of a cosy, energy-efficient home is insulation, which plays a huge role in heat retention, fire resistance, and sound protection. You can find insulation in many forms, such as boards (multi-application), slabs (walls) and rolls (loft insulation). Depending on the application, you will need only one of these, while at other times, all three may be appropriate.
