Why do 10A Thin Smoke Vent Skylights Leak?
Release time：
A common issue plaguing many industrial plants is water leakage from 10A thin ventilating skylights. While seemingly minor, such leaks can disrupt the workshop environment and even damage equipment. Industry experts indicate that the root causes primarily lie in two areas: the design and quality of the rain deflector, and non-compliant installation practices.
First Culprit: Flaws in Rain Deflector Design and Quality
The rain deflector is the primary component of the 10A thin ventilating skylight responsible for blocking rainwater. Leakage problems can be inherent if its design is flawed. Common issues include an insufficient slope angle, which hampers rapid water runoff, or improper width/length dimensions leading to "water bypass," failing to effectively block wind-driven rain. More directly, substandard materials are a frequent cause. Inferior deflectors made from low-strength materials are prone to cracking and fracturing under prolonged exposure to the elements, creating direct pathways for water ingress. Furthermore, the connection method between the deflector and the drainage gutter is critical. While integrally molded designs minimize seams, some products use nailed connections. Over time, these nails can rust and corrode, gradually widening the gaps and allowing water to seep through.
Second Culprit: Non-Compliant Installation Practices
Even with a qualified rain deflector, unprofessional installation can introduce serious leakage risks. Improper tools or techniques during installation can easily damage the protective coating on the MCW1 ventilating skylight's metal panels. Once this coating is compromised, prolonged exposure to a humid environment leads to rapid rust and corrosion, eventually creating leaks at the weakened spots. Equally important is the waterproofing at the interface between the skylight and the roof deck. Failure to properly install waterproof membranes or the uneven application of sealant at these joints allows water to infiltrate. Careless on-site practices, such as workers stepping on roof panels or dragging materials, can deform roof sheets, ridge cappings, or gable panels. This deformation causes panels to lift at connections and creates poor overlaps, forming gaps for water entry. Additionally, exposed roof screws of subpar quality can snap due to equipment vibration or thermal expansion/contraction, leaving behind holes that become direct entry points for moisture.
In summary, leakage in 10A thin ventilating skylights is often the result of insufficient control in both "design quality" and "installation compliance." To fundamentally mitigate leakage risks, it is crucial to select skylights with careful attention to the rain deflector's design details and material quality, and to ensure installation is carried out by a professional team.
