Aluminum Siding
Aluminum siding is durable, low maintenance, and available in various shapes and sizes including horizontal strips to mimic wood clapboard siding, vertical strips to mimic wood board and batten siding or in larger sheets with vertical channels as is typically seen on larger warehouses.
Be aware of the thickness of the aluminum. Heavier gauge aluminum siding will be more durable under extreme weather conditions and could have an increased lifespan.
While aluminum siding has a long lifespan, it also has high embodied energy impact due to the extraction and manufacturing processes. As well, it is not entirely maintenance free; coatings on aluminum siding such as paint may deteriorate after only 10-25 years and require re-application to maintain aesthetics.
