For window awnings, entrance canopies, patio roofs and daylighting structures, buyers often need to balance natural light transmission, material performance and outdoor installation requirements. 10mm Polycarbonate Hollow Sheet is an option worth considering for these roofing applications.
However, “10mm” is only a basic specification. Professional buyers should also evaluate luminous transmittance, haze, impact performance, UV-related data and thermal expansion.
For roofing systems that require natural light, luminous transmittance is an important selection parameter. Instead of relying on descriptions such as “clear” or “high transparency,” buyers can use measured data to compare different products.
The tested polycarbonate hollow sheet had a thickness of 10mm and a sample size of 600 × 600mm. Its measured luminous transmittance was 82%, compared with a stated requirement of at least 70%. The haze result was 2.4%.
For window awnings and entrance canopies, these values provide useful technical references when evaluating daylighting performance.
Impact performance is another important consideration when selecting a Polycarbonate Roofing Sheet for outdoor applications. Buyers should look at the actual test conditions rather than relying only on general terms such as “impact resistant.”
The tested 10mm sample underwent a 15J drop-weight impact test, using a 1.0kg hammer from a height of 1.53m. Ten impacts were performed, and no damage was observed.
This laboratory result should not be interpreted as a guarantee against every type of weather-related impact. Actual roofing performance also depends on span, support spacing, fasteners and installation design.
Outdoor roofing materials are exposed to sunlight, making UV-related performance an important procurement consideration.
The test report recorded a UV transmittance of 0.0009% for the tested sample.
This value can be used for technical product comparison. However, UV transmittance alone does not establish a fixed service life or prove a specific UV-coating structure. Buyers should confirm the actual UV protection method and product configuration with the supplier.
Polycarbonate sheets experience dimensional changes as temperature changes. Thermal expansion should therefore be considered when designing an outdoor roofing system.
The two reported thermal-expansion results for the tested sample were 3.48 × 10⁻⁵/°C and 2.81 × 10⁻⁵/°C.
Such data can help installation or structural teams consider appropriate expansion clearance, fastening methods and connection details.
Before purchasing, buyers should confirm:
When selecting a 10mm Polycarbonate Hollow Sheet, thickness should not be the only consideration. For outdoor awnings and daylighting roofs, measurable parameters such as 82% luminous transmittance, 2.4% haze, 15J impact-test performance and 0.0009% UV transmittance provide a clearer technical basis for product evaluation.
For B2B procurement, comparing specifications, test data and installation requirements together is generally more informative than comparing price or product images alone.
