Rather than rolling or sliding like conventional doors, the Rollashield CD door stacks at the top of the opening. This gives a huge benefit in terms of headroom requirements over a traditional sectional door and still provides excellent levels of insulation. The door also provides good security due to an automatic anti-lift locking system. It is a quiet and low maintenance door, requiring minimal structural support.

Rollashield CD doors offer superior resistance to all weather conditions; along with offering security and excellent insulation. These qualities, combined with simple and efficient operation makes them a popular choice for external doorways on temperature-controlled buildings.
