K77 & K55 Foam Filled Aluminium Shutter

Lightweight insulated shutters with a condensed design to save as much space as possible Download
L20 Spec.

K77 and K55 foam filled aluminium roller shutters are the ideal choice for openings with limited headroom, like garages, kiosks and receptions. They offer all the benefits of insulated shutters, but in a condensed design to help utilise as much space as possible.

The K77 shutter consists of 77mm double skinned foam filled aluminium slat and gives a medium security level with insulation properties. It’s a versatile shutter that can be used for a range of applications.

The K55 uses a 55mm slat and has an even smaller coil, so it’s ideal when there is very little headroom.

Description K77 / K55 Aluminium roller shutters

The K77 and K55 insulated aluminium roller shutters are the ideal choice for garages and other spaces (such as receptions) with very little or no headroom at all. They have a condensed design to help utilise as much space as possible.

This exceptional, yet pleasantly priced insulated roller shutter door has been specifically designed to improve on many of the virtues of both sectional overhead doors and traditional steel roller shutters.

Available in a range of colours, including simulated wood grain. A high quality powder coated corrosion resistant finish of all the exposed parts makes these shutters suitable for almost any situation.

Insulated aluminium security shutters

K77 / K55 aluminium roller shutters are ideally suited for residential premises and garages (quiet operation), offices, day-centres, hospitals and schools (low headroom), as well as shopping malls and shops.
