Before installation, check whether all components are intact and free from deformation. If any damage is found, repair or replace them promptly. Key design points for roof ventilation and daylighting skylights include determining reasonable opening sizes based on different usage requirements and architectural characteristics.
Ventilation skylight quotations are calculated per meter or square meter. As they are custom non-standard products, even for the same model, the specifications, material configurations, and technical requirements vary depending on ventilation needs, leading to differences in price per meter or square meter.
Ventilation skylights operate through wind pressure differences, utilizing the pressure disparity between the windward and leeward sides of a building to facilitate air circulation. The magnitude of this pressure difference depends on the building's shape, surrounding environment, and the angle between the building and wind direction.
The layout of ventilation skylights on roofs can be horizontal or vertical, corresponding to ridge skylights and slope-aligned skylights in professional terms. Ventilation methods include natural open type and electric open-close type. The natural open type, commonly referred to as direct exhaust skylights, allows indoor heat, stale air, smoke, and dust to be directly expelled outdoors through the skylight opening.
After ventilation skylight materials are hoisted onto the roof, they should be promptly distributed to prevent the roof panels and beams from being overloaded or deformed. First, move the main frame of the skylight to the skylight base, placing one main frame every three meters. Skylight tie rods, rain shields, flashing plates, ridge tiles, water collection troughs, downpipes, and raft boards should be distributed and arranged according to specified intervals. In windy conditions, secure the materials to prevent them from being blown off and causing injury.
