Project Overview
This curved skylight roof project demonstrates the versatility and durability of Jietai corrugated polycarbonate sheets in architectural applications. The client required a lightweight, translucent roofing solution that could follow a curved structural design while providing natural daylighting and weather protection. Installed in a commercial building, this curved skylight spans an area of approximately 200 square meters, creating a bright and open atmosphere for the interior space below.
The Challenge
The primary challenge was achieving a smooth curved installation without compromising the structural integrity of the polycarbonate sheets. Standard flat sheets cannot follow curved roof profiles, requiring careful selection of materials that could withstand bending stress. Additionally, the skylight needed to provide uniform light diffusion while preventing water leakage at the curved joints, which are more complex than straight-line connections.
Our Solution
Jietai recommended our high-quality corrugated polycarbonate sheets with enhanced flexibility and UV protection. The sheets were installed on a pre-fabricated curved aluminum framework, using specialized sealing profiles at all joints to ensure watertight performance. The corrugated profile provided natural structural rigidity even when curved, while the UV co-extrusion layer guaranteed long-term weather resistance without yellowing.
Results
- Successful curved installation covering 200m² commercial skylight area
- Natural daylight transmission reducing artificial lighting needs by approximately 40%
- Zero leakage after multiple heavy rainfall tests
- Estimated 15+ year service life with UV warranty
- Completed within the projected 2-week installation timeline
The corrugated profile of our polycarbonate sheets proved ideal for this curved roof application, as the wave pattern provides natural flexural rigidity while allowing the sheet to follow the arched framework. Installation was carried out using specialized curved aluminum profiles that matched the sheet wave pattern, ensuring a watertight seal at every connection point. The clear polycarbonate panels allow maximum daylight penetration while diffusing sunlight to reduce harsh shadows and glare in the interior space below. This creates a pleasant working environment while reducing the need for artificial lighting during daytime hours. UV protection is critical in skylight applications as prolonged sun exposure can cause material degradation and yellowing over time. Our co-extruded UV layer, applied during the manufacturing process rather than as a post-treatment coating, ensures uniform protection across the entire sheet surface that will not peel, flake, or wear away over the lifetime of the installation.
