What Is Multiwall Polycarbonate?
Multiwall polycarbonate sheets are hollow structured panels with multiple internal walls that create insulating air chambers. The twin-wall configuration enhances structural performance and thermal efficiency while remaining lightweight and cost-effective.
Compared to solid polycarbonate or glass, multiwall panels offer significantly better U-values — meaning less heat transfers through the sheet in either direction.
