Loft insulation refers to the process of insulating the space between the roof and the ceiling of a building, commonly known as the loft or attic. This insulation helps to reduce heat loss through the roof, making the building more energy-efficient and comfortable.
Cavity wall insulation is a method of improving the thermal efficiency of a building by filling the gap (or cavity) between the external and internal walls. This insulation helps to reduce heat loss and can lead to significant energy savings and increased comfort within the building.
Internal wall insulation (IWI) involves insulating the interior walls of a building to improve thermal efficiency and enhance comfort. Unlike cavity wall insulation, which fills the gap between external and internal walls, internal wall insulation is applied directly to the interior surface of external walls.
External wall insulation (EWI) involves applying insulation materials to the outside surface of a building's external walls. This method enhances thermal efficiency by creating a continuous layer of insulation, reducing heat loss and improving overall energy performance.
