Product Type

Lumina Slate Series

Mid-Sized Residential Application: Unlike sprawling estates, this villa had a more compact roof footprint (145 sq.m). The client needed a highly efficient 6kW system to offset daily power consumption while maintaining a sleek, unobtrusive look that matched the upscale neighborhood.
Weather Resistance & Ventilation: Beijing experiences distinct seasons with heavy summer rains. The developer required absolute assurance regarding the roof’s long-term waterproofing capabilities and underneath ventilation to prevent moisture buildup.

Pro-Level Underlayment System: We applied the Lumina Slate (Pro) series using a specialized wooden batten framework. As our site photos demonstrate, the combination of corrugated waterproof underlayment and counter-battens ensures optimal cross-ventilation and a 100% watertight seal beneath the solar tiles.
Elegant Aesthetic & ROI: The result is a stunning, flush-mounted dark slate roof that effortlessly sheds rainwater while generating a reliable 7,200 kWh annually, delivering both architectural beauty and tangible financial returns.
