K25/K-lite Aluminium Roller Shutters

Versatile aluminium security shutters in a variety of styles

Aluminium security shutters have a number of advantages over heavier steel roller shutters. They are small and elegant, yet lightweight and strong. Moreover, our aluminium roller shutters are quiet in operation and require little maintenance.

Description K25/K-lite roller grilles

The K25 and K-Lite Aluminium Roller Shutters are very popular, because they can be used in many different applications, both internally and externally.

They are elegant, quiet to operate, and roll up into a small box. This makes them really useful in situations with limited headroom.

The foam-filled K-Lite is a very cost-effective product, suitable for low risk security applications. Optionally, it can have venting slots along the horizontal joins to allow for some basic air flow in domestic situations. For more strength and medium to high risk situations, the K25 is the right choice.

Available punched of perforated

The K25 is also available either punched or perforated to allow visibility and airflow through the shutter.

Insurance approved

The K25 roller shutter is also available in a high security, insurance approved version. Approval has been gained as a result of independent testing to Loss Prevention Standard (LPS) 1175 Security Rating Classification 1.
