Sectional Overhead Doors
Sectional overhead doors are used when side room is limited and a higher insulation value (thermal or acoustic) is required than can be provided by a roller shutter door. Head clearance can be a challenge but different vertical lift designs including high-lift or profile-lift (where the door panels follow the roof contour) can be used to minimise this problem.
At NDS we repair and maintain doors up to 3m high! And test to current standards.
We offer full-service maintenance programs that are designed to keep your doors operating smoothly without any hassle.
