Twin wall polycarbonate sheeting provides increased insulation, heat retention, and is extremely durable. With 8 mm of dead air space in-between each side of every sheet, there is an increased insulation R-value when compared to single or double inflated standard greenhouse plastics. 

In addition to its insulation properties, 8 mm Twin Wall Polycarbonate is warrantied for 10 years against UV degradation with a useful life ranging between a 15 to 20 years.

This greenhouse plastic does fantastic in windy environments due to its rigid design, and because of its strength it is a popular end-wall covering for greenhouses, high tunnels, and hoop houses. Its resistance to wind damage makes 8 mm twin wall polycarbonate a great choice to reduce future maintenance.
