Urban Renewal Drives Building Daylighting Upgrade:Baoding Sinhai Plastic Sheet Co., Ltd. Empowers City Space Renewal with 30 Years of Craftsmanship

In 2025, China has entered a critical period for urban renewal.

Over 32,000 urban renewal projects have been launched nationwide with total investment exceeding 5 trillion yuan, covering old residential renovation, historic district protection, commercial building renovation, and municipal facility upgrades.

PC polycarbonate sheets have emerged as the star material for commercial building renovation due to their light weight, high strength, excellent daylighting, and construction convenience.

Compared to traditional glass, PC boards offer unique advantages in commercial building applications:

• Lightweight and high strength: PC board weight is only 1/12 of glass, dramatically reducing structural loads and eliminating the need for structural reinforcement in existing building renovations.

• Superior daylighting: With 82% transmittance and special optical diffusion formula, PC boards convert direct sunlight into uniform, soft diffused light, eliminating glare and shadows for comfortable commercial environments.

• Outstanding energy efficiency: PC hollow-core boards' thermal insulation far exceeds glass, reducing commercial building air conditioning energy consumption by 25%-35%.

• Design flexibility: PC boards can be cold-formed into various arcs and curves, enabling architects' creative visions.

Xinhai Sunlight Board Manufacturing Co., Ltd.

has established clear competitive advantages in the commercial building renovation market.

The company provides complete product systems covering commercial complex skylights, canopy corridors, atrium domes, and glass curtain wall frames.

Products have passed strict fire safety testing with B1 flame retardancy, meeting public building fire requirements.

For historic district protection projects, the company developed heritage-style PC board products that harmonize with traditional brick and tile materials while meeting modern daylighting needs.

For large-span atrium renovations, the company provides PC hollow-core sunlight board systems with single spans exceeding 8 meters, reducing seams for better waterproofing and appearance.

Looking ahead, the company will continue to innovate in urban renewal applications, exploring integration with renewable energy and sustainable design to contribute to China's urban space quality improvement.
