## Questions & Answers

**Q: Do greenhouse panels have a uv coating on single side or both sides?**
A: Our panels feature a coating on both sides, so there is no need to distinguish between the front and back during installation.

**Q: Is there any deviation in the panel dimensions?**
A: Our panels are machine-cut. Although machine cutting offers high precision, factors such as thermal expansion and contraction of the material, tool wear, and conveyor positioning may still result in a standard industry tolerance of +/- 0.394 inches.

**Q: How to avoid installation problems caused by dimensional errors?**
A: We recommend allowing for a slight margin of adjustment during installation. Dimensional variations falling within standard tolerance limits can be easily accommodated using trim strips or sealing strips, without compromising overall functionality.

**Q: For which scenarios are these 3 panel thicknesses (0.16/0.24/0.32 in) respectively suitable?**
A: 0.16 inches is suitable for simple greenhouses and everyday shading. 0.24 inches is suitable for standard greenhouses and skylights. 0.32 inches is suitable for regions prone to strong winds and heavy snow, as well as for long-term outdoor use.

**Q: How to choose between 4ft and 6ft greenhouse panels?**
A: The 4ft panels are lightweight and easy to handle and install, making them suitable for small greenhouses. The 6ft panels feature a wider span and fewer seams, offering waterproofing and sealing capabilities, making them ideal for large greenhouses.
