A 3-Dimension Comparison of Linear Electric Smoke Exhaust Skylights from Different Manufacturers
Release time：
Many purchasers find that the same type of linear electric smoke exhaust skylight from different manufacturers shows significant differences in price and performance. The core disparities lie in three critical dimensions: waterproof performance, structural stability, and smoke exhaust safety.
Waterproof Performance is the primary differentiator, mainly evident in waterproofing technology. Reputable manufacturers of linear electric smoke exhaust skylights adopt structural waterproof design. By integrating the skylight frame profiles into a single piece, they eliminate corner joints, eschew adhesive-based waterproofing, and utilize built-in internal drainage to channel rainwater away. This creates a comprehensive waterproof barrier suitable for long-term exposure to wind and rain. In contrast, some smaller manufacturers rely on simple adhesive waterproofing, where the glue is prone to aging and cracking. This often leads to leakage issues later on, seriously endangering the safety of equipment and materials inside the building.
The gap in Structural Stability stems from whether professional load calculations are performed. Legitimate electric smoke exhaust skylight manufacturers conduct specialized structural designs based on the climatic conditions of different regions, accounting for factors like strong winds, snow accumulation, and earthquakes. This ensures the skylight remains undeformed and non-collapsible under extreme weather. Some non-standard manufacturers, however, omit load calculations to cut costs. Their products are prone to structural instability in environments with high winds or heavy snow, posing significant safety risks. Alternatively, manufacturers with inadequate technical capabilities may perform inaccurate structural calculations, also leading to potential collapse or deformation of the window unit.
Differences in Smoke Exhaust Safety directly impact firefighting effectiveness. Reliable manufacturers' products precisely meet the required smoke exhaust area, are paired with high-performance drive motors for rapid smoke extraction, and ensure stable, uninterrupted operation during exhaust. Their electrical control boxes and electric window actuators have passed CCCF (China Compulsory Fire Protection Product Certification). Inferior products often suffer from slow smoke exhaust, insufficient effective exhaust area, and unstable operation. In a fire, they may fail to promptly remove dense smoke, delaying evacuation and rescue efforts.
In summary, when procuring linear electric smoke exhaust skylights, it is essential to thoroughly evaluate these three dimensions. Priority should be given to manufacturers with mature craftsmanship that emphasize structural design and safety performance, thereby avoiding potential safety hazards arising from product deficiencies.
