Spanker International offers a range of PVC strip doors. Large assortment of materials and attachment methods provide the variety. The fact that each curtain is custom made for users’ unique requirements and to individual specifications assures the flexibility to assist in any controlled environment application. Transflex Polar PVC material maintains flexibility at temperature as low as -40°C. It improves shelf life without inhibiting product appeal, keeps warm moist air out, thus reducing moisture and frost built up and coil icing. Under some conditions when PVC strips are used in a cool or freezer room application there may be a tendency of the strips to curl inwards at the bottom. It is usually caused by a chill factor of cold air circulation from the fan coil of the refrigeration unit, which causes the PVC inside face to contract.
