Some doors just need
to do the job.

Not every door needs to be the most beautiful thing in the room. Some doors need to do a job reliably, durably, and without fuss for the lifetime of the building they’re installed in.

The Sentinel is that door. Built on the Jansen Economy 50 profile, it combines certified fire resistance from E30 to E120 with acoustic insulation up to 44dB, Class 4 air permeability and Class 8A water tightness. It works internally and externally, across residential, commercial and public building applications, and handles everything from standard single doors to arched configurations and smoke-control specifications.

The 105mm face width keeps it clean and considered rather than heavy steel that reads as architectural rather than industrial. And because every door is manufactured to order, it can be finished in raw steel, galvanised steel or stainless steel, with the full RAL palette available in powder-coat or wet paint.

Practical, certified and built to last. Sometimes that’s exactly what a project needs.
