Which material is typically utilized in double-walled glazing systems?

Double-walled glazing systems are designed to improve thermal insulation and energy efficiency in buildings, particularly in greenhouses and plant nurseries. The typically utilized material in these systems is polycarbonate sheets.

Polycarbonate is favored due to its excellent thermal properties, lightweight nature, and high impact resistance compared to traditional glass. It provides a significant reduction in heat loss and can diffuse light effectively, creating a more suitable environment for plant growth. The air gap between the two layers of polycarbonate enhances insulation, reducing the energy needed for heating or cooling.

In contrast, single-pane glass lacks the insulating properties needed for a double-walled system and would not serve the same purpose. Wood panels can provide some insulation but are generally not used in glazing systems due to their bulk and susceptibility to moisture. Fiberglass, while it has some insulating qualities, does not have the same clarity or light transmission capabilities as polycarbonate, making polycarbonate the superior choice for maximizing light while providing energy efficiency.
