Frequently Asked Questions
Will U-Lock panels make my restaurant too hot in summer?
No. The multi-wall hollow structure provides excellent thermal insulation. Opal White or Bronze panels reduce solar heat gain while still transmitting diffused natural light. Proper ventilation planning further enhances comfort.
Can U-Lock panels be installed over an existing patio or deck?
Yes. The lightweight nature of polycarbonate panels means they can often be installed over existing structures without major reinforcement. Our technical team can assess your specific situation.
How do U-Lock panels compare to glass for sunrooms?
U-Lock polycarbonate panels are 200 times more impact-resistant than glass, 60% lighter, provide better insulation, and cost significantly less. They are the superior choice for most restaurant and sunroom applications.
