Although this fixed sunroom is not as ventilated as an electric sunroom, it can be customized with sliding doors, windows and skylights to ensure ventilation in the indoor sunroom. The profile structure ensures strong load-bearing capacity and can easily withstand winds below level 12 and snow accumulations below 50mm thick. Even the frame can be customized. We can use a small frame while ensuring strength, making the whole more aesthetically pleasing. Overall, this product is very cost-effective. Five years warranty period.
