Description
Choice of Drive Systems
Positive drive – The door curtain is driven positively when closing as well as opening, by means of a toothed driving wheel engaging in a side belt on the door curtain.
Low-friction drive – Doors have low-friction side guides for quiet operation. The door is opened by a conventional roller and closes under its own weight. The advantage of both drive systems is that there are no heavyweight elements, which makes the door safer and requiring less maintenance. A further advantage of the Positive drive is that it will operate smoothly under greater wind pressures than the Lowfriction.
Environmental Benefits
Speed of operation minimises open time, thus reducingheat loss from the building, conserving energy andlowering CO2 emissions.
Rapid Payback
Energy savings reduce fuel bills and mean that doors have a shorter payback period. We can provide a costm analysis for specific installations to demonstrate savings.
Comfort Condition
Rapid operating times help to maintain internaltemperatures, so improving staff working conditions, and reducing entry of pollution, dust, vermin and noise.
Standard Compliance
All doors are CE marked and comply with and generally exceed applicable European harmonised standards including EN 13241-1. Industrial, commercial and garage doors and gates.
Door Selection
All doors are purpose-made for each project. The table below summarises the range available. Doors sizes and speeds are indicative only, and greater speed, width or height may be possible in individual cases. For the weather performance view our brochure for a complete overview
