K25 Perforated Aluminium Roller Shutters

Modern design and maximum transparency for a bright and open space Download
L20 Spec.

The K25 Perforated offers a lighter alternative to our standard K25 aluminum security shutter. Utilizing a single-wall extruded aluminum slat with a multitude of micro-perforations, it gives a semi-transparent look to the shutter curtain.

Similar to all K25 aluminum roller shutters, the K25 Peforated combines lightweight construction with robust strength. Operating quietly and needing minimal maintenance, this compact roller shutter is ideal for medium-security applications, including homes, reception desks, bars, and offices.

Description K25 Perforated roller grilles

The K25 Perforated Aluminium Roller Shutter is a versatile and popular choice, offering a wide range of applications for internal use or external use behind glass.

Like all K25 roller shutters, they operate quietly and roll up into a compact box. This feature is particularly advantageous in spaces with limited headroom, providing a practical solution without sacrificing style.

Multitude of microperforations

Designed for various security needs, the K25 Perforated stands out with its single-wall aluminum lath featuring numerous small micro-perforations.

These perforations not only allow for the passage of air and light but also provide a unique visual element. In daylight and from a distance, the curtain appears solid, but when lit from one side, it takes on a semi-transparent appearance.

A balance of security and aesthetics

Whether used in storefront situations where visibility is essential or in spaces requiring a balance between security and aesthetics, the K25 Perforated offers a reliable solution.

Its adaptability, coupled with the durability of aluminium construction, makes it suitable for medium-risk security situations, providing both peace of mind and a modern aesthetic.
