The canopies are often lined with sound-absorbing materials that dampen the noise produced by the generator. This is crucial in populated areas or applications where noise levels are a concern. The design typically involves multiple layers of composite materials that reflect sound waves into the enclosure, while soft, porous materials absorb the sound, converting it into heat.

Constructed from durable materials like steel or aluminum, these canopies shield the generator from rain, wind, dust, and other harsh weather conditions. Features like a cambered roof prevent water accumulation, and enclosed exhaust systems ensure safety and protect against rust.

Proper ventilation is key to prevent overheating. Canopies allow for unrestricted air drift and airflow, ensuring the generator does not choke out or overheat, even in extreme weather conditions.
