Which Ventilation Skylight Is Best? How to Choose Between Low-Profile and Curved Types?
Release time：
Ventilation skylights are essential equipment for factory roofs, yet choosing between the mainstream low-profile and curved types often presents a dilemma. In reality, each type suits specific scenarios. The key to precise selection lies in aligning the choice with your building's requirements and operating environment.
Curved Ventilation Skylights (corresponding to the TC1-TC8 series in the Chinese national standard drawing 18J621-3) utilize both thermal buoyancy and wind pressure to drive natural ventilation, offering outstanding ventilation efficiency. Constructed from peripheral cladding, frames, and rain deflection panels, they boast a wind pressure resistance of 1.0-1.2 kPa and a snow load capacity of 0.2-0.6 kN/m², making them suitable for industrial plants with high ventilation demands, such as in the power and metallurgy sectors. Their opening width can extend up to 6000mm, with length easily customized through modular combinations. The curved structure reduces wind resistance and provides protection against rain and snow. For areas with heavy wind and snow, operable models are available, which can be paired with 24V safety power supplies or solar drives for practical and energy-efficient operation.
Low-Profile Ventilation Skylights (TC9-TC10 series) feature a compact structure with a low profile and reduced steel usage, operating primarily as gravity-driven, stack-effect ventilators. They offer easy modular assembly, low wind resistance, and excellent rain protection, providing an effective ventilation area of 1.2-4.8 m² per meter of length. Among them, the TC10A model employs a parallel air duct design, delivering high-efficiency ventilation and smoke exhaust. It is widely used in high-temperature workshops like those in metal processing, new energy, and new materials industries. The TC10E model includes anti-snow features, making it ideal for snowy northern regions. Intelligent low-profile skylights can integrate with fire alarm systems to meet smoke exhaust requirements. Their installation requires minimal roof modification and is compatible with both steel structures and reinforced concrete buildings.
Choosing the right ventilation skylight not only improves indoor air quality but also reduces energy consumption. By carefully matching the skylight type to your building's specific design, required ventilation rate, and environmental conditions, you can ensure that either a low-profile or curved ventilation skylight delivers maximum performance.
