Description

A space-saving lightweight aluminum industrial door which combines the insulation and airtightness of a sectional door with the headroom requirements of a roller door. The doors stack at the head of the opening with smooth and quiet operation, and can be specified for high use openings.


The Shutter stacks at the head of the opening, this helps to overcome common issues with rolling and sliding doors. The doors offer a high level of insulation performance and security, as well as being simple to fit into a wide range of building designs with minimum steelwork or structural requirements. Rollashield Stack doors are quiet to operate and low-maintenance. The doors are electrically operated via high-performance industrial motors and have a range of safety features including fall-safe devices and manual overrides.


A wide range of control options can be specified to maximize the doors usability. The 40 mm insulated panels offer a U-Value as low as 0.76 W/m²K and sound reduction of 20 dB, as well as tested air permeability and water penetration of Class 2. Security performance is excellent with an automatic anti-lift locking device. The composite insulated panels are available in eight standard colours, or can be painted to a wider range of RAL colours to blend with the buildings architecture. It is also possible to supply the doors with a range of vision panels including slim aluminum frames, which provide an attractive choice for vehicle showrooms.
