IDA 2024 NOW OPEN -- Final Deadline November 30, 2024
For the manhole on the roof, there is Skylight Manhole Vent. First, natural sunlight can still permeate the building when it is closed. Second, as it is closed, the heat can be exhausted by two exhaust tubes on both sides. The third highlight is its patented leak-proof design. Fourth, it is condensation-proof. Fifth, you can open it easily and safely. Sixth, multiple units could be conjugated into as many as you want due to the modularized design. Seventh, it reduces the pitter-patter of rain due to its aluminum and glass surface, producing less noise than a traditional stainless one.
