Complete Buying Guide for Polycarbonate For Greenhouse
Essential Factors We Consider
When selecting polycarbonate for greenhouse roofing, you should look at thickness, UV resistance, and light transmission. Thicker panels generally offer more insulation and protection, while higher light transmission ensures your plants get the energy they need. Don’t forget to check if the product includes a UV-protective layer, as this prevents the material from becoming brittle or yellow over time.

Remember that investing in a higher-quality panel now can save you from having to replace your roof in a few short seasons.

Frequently Asked Questions
Q: Does polycarbonate yellow over time?
