What are the essential details to note when installing skylight panels?

Improper installation can lead to leaks and damage; here are 3 key details:

• Joint LengthThe transverse overlap must be ≥10cm, the longitudinal overlap must be ≥15cm, and the overlap must be aligned with the dominant local wind direction to reduce the risk of rainwater backflow.
• Fixed ApproachEnsure the use of specialized waterproof gaskets and self-tapping screws. Do not overtighten the screws to prevent cracking the panels; maintain a screw spacing of 30-50cm for even distribution of force.
• Reserved expansion jointsSkylight panels expand and contract with temperature changes, so a 5-10mm expansion joint should be left every 6 meters during installation to prevent deformation and cracking of the panels.
