Aluminium Composite Panels (ACP), as their name suggests, are one of the most popular materials in today’s construction. They’re known for their sleek appearance and structural flexibility but they’re also important when it comes to improving the energy efficiency of a building.
ACPs’ energy properties are attributable to the main composition of the sheet. The material consists of two aluminium layers with an inner core of solid polyethylene or mineral which reduces heat transfer.
The most direct energy savings from ACP sheets is to reduce HVAC energy use. In a poorly insulated building envelope, air conditioning and heating systems must operate more vigorously in order to provide a comfortable climate inside the building.
ACP sheets reflect a considerable amount of solar radiation particularly with light coloured sheets and metalite finishes. This attribute is especially valuable for hot climates where solar gain into buildings is a significant issue.
Making buildings energy efficient isn’t just about heating and cooling. Weight of cladding material has an impact on energy allocated to supporting structure and building production. ACP sheets are significantly lighter than cladding with traditional stone, brick or glass.
When walls and insulating material are damp, it is an invisible source of energy loss. Once insulation is wet, it is not as effective. ACP sheets are naturally moisture resistant and provide an additional barrier to moisture to protect the interior wall assembly.
Degradable materials have to be replaced regularly, which is expensive and impacts the environment.
ACP sheets combine the design aesthetics, durability and energy performance in one cladding solution.
