A Look at Sealing and Waterproofing Performance
Release time：
The sealing and waterproofing performance of an electric smoke vent is a critical concern for clients, as it directly impacts building safety and long-term usability. A high-quality Linear Electric Smoke Vent achieves reliable water resistance through scientific design and premium materials, effectively shielding interiors from wind and rain.
Sealing materials form the foundation of waterproofing. These vents typically employ Ethylene Propylene Diene Monomer (EPDM) rubber gaskets. Known for exceptional weather resistance, EPDM can withstand extreme temperatures, UV exposure, and harsh environmental conditions without significant aging or cracking, maintaining its elasticity and sealing integrity over the long term. The gasket is fitted along the entire perimeter where the vent frame meets the building curb, creating a continuous, closed seal that blocks the primary path for water ingress.
Structural waterproofing design further reinforces this defense. Linear Automatic Smoke Vents often feature a one-piece, integrally formed frame that eliminates seams at the corners—a common weak point for leaks. Additionally, they are equipped with internal drainage channels. The vent's glazing panels are installed at a calculated pitch, allowing rainwater to shed quickly and be channeled away from the building envelope, preventing accumulation that could lead to seepage. It is advisable to avoid vents that rely primarily on sealants for waterproofing, as these adhesives can degrade, crack, and fail over time, eventually causing leaks.
In practical application, a certified Linear Electric Smoke Vent undergoes rigorous waterproofing tests and is engineered to maintain a dry interior even during heavy downpours. This robust sealing not only protects the building structure from water damage but also safeguards the vent's internal electrical components from moisture, ensuring the reliable operation of both smoke exhaust and daylighting functions. This makes it a suitable choice for a wide range of industrial and commercial buildings with demanding waterproofing requirements.
