Project Overview
This residential sunroom project demonstrates how Jietai solid polycarbonate sheets create comfortable, light-filled living spaces. Added to an existing family home, this sunroom extends the usable living area by 25 square meters, providing a bright recreation room that can be enjoyed year-round regardless of weather conditions.
The Challenge
The sunroom needed to maintain comfortable interior temperatures throughout all four seasons without relying on excessive heating or cooling. The client wanted maximum natural light without the heat gain problems associated with standard glass conservatories. Additionally, the structure had to match the architectural style of the existing home while meeting local building codes.

Our Solution
Jietai supplied 10mm multi-wall solid polycarbonate sheets for the sunroom roof, providing superior insulation compared to single-layer glass. The sheets feature a solar control coating that reduces heat gain in summer while retaining warmth in winter. Clear panels for the walls allow unobstructed garden views, while the solid construction provides excellent sound insulation from exterior noise.

Results
- 25m² sunroom completed in 3 weeks
- Interior temperatures maintained at 15-28°C year-round without HVAC
- Natural light levels comparable to glass but with reduced glare
- Summer interior temperatures 5-8°C lower than equivalent glass structure
- Seamless integration with existing home architecture
Sunroom additions are a popular home improvement project that creates versatile living space while connecting homeowners with their outdoor environment. This residential sunroom project utilized Jietai 10mm solid polycarbonate sheets for the roof panels, providing superior insulation performance compared to traditional glass conservatory roofs. The multi-wall construction traps air between layers, creating an effective thermal barrier that reduces heat loss in winter and limits solar heat gain in summer. A solar control coating reflects a portion of infrared radiation while allowing visible light to pass through, preventing the greenhouse effect that can make glass sunrooms uncomfortably hot during summer months. The result is a comfortable, usable space that requires minimal supplemental heating or cooling throughout the year. The polycarbonate panels are significantly lighter than glass, reducing the structural load requirements and allowing for simpler, more cost-effective framing. UV protection prevents the panels from yellowing over time, and the material’s impact resistance provides peace of mind against hail, falling branches, and accidental impacts.
Why Jietai
Jietai’s solid polycarbonate sheets for sunroom applications combine thermal insulation, UV protection, and aesthetic appeal. Our materials are used by professional builders and DIY homeowners alike, offering factory-direct quality at competitive prices.
