Imagine stepping into a lush oasis regardless of the season—where vibrant plants thrive whether it's freezing outside or scorching hot. This vision can become reality with the right greenhouse materials. Greenhouses serve as protective sanctuaries for delicate plants, extending growing seasons, shielding against harsh weather, and providing stable growing conditions. The choice of construction material significantly impacts performance, cost, and longevity.
The Polycarbonate Family: Diverse Options for Every Need
Polycarbonate panels come in several varieties, each with distinct characteristics:
-
Double-wall panels:
The focus of this guide, offering excellent insulation, good light transmission, and moderate pricing—ideal for greenhouse construction.
-
Solid panels:
Higher strength and impact resistance but more expensive, better suited for high-security applications.
-
Corrugated panels:
Effective drainage and wind resistance but with reduced light transmission.
-
Textured panels:
Surface treatments diffuse light to prevent plant scorching.
-
Mini-corrugated panels:
Lightweight and easy to install for small projects.
Double-wall polycarbonate stands out with its unique sandwich structure—two plastic sheets separated by supporting ribs—creating a lightweight yet sturdy construction that handles environmental challenges with ease.
Key Advantages of Double-Wall Panels
The air gap between layers creates natural insulation, slowing heat transfer significantly. During summer, heat must penetrate the outer layer, traverse the air buffer, then reach the inner layer—this graduated effect maintains stable interior temperatures. In winter, the same principle retains warmth, reducing heating costs.
Additional benefits include:
-
Cost-effectiveness compared to glass
-
Exceptional durability and impact resistance
-
Chemical stability against corrosion
-
Inherent flame retardancy
-
Flexibility for curved installations
-
Scratch-resistant surfaces
-
Waterproof construction
-
Superior thermal performance versus glass
-
Excellent light transmission for photosynthesis

Choosing Between Double-Wall and Multiwall Panels
While both offer excellent performance, key differences exist:
-
Double-wall:
Better light transmission, lighter weight, easier installation, and lower cost
-
Multiwall:
Enhanced insulation for extremely cold climates
For most applications, double-wall panels provide the optimal balance of insulation and light transmission.
Structural Integrity and Flexibility
With impact resistance 200× greater than glass, these panels withstand severe weather conditions. Despite their strength, they remain flexible enough for curved installations when bent along their length.
