The Humber™ Zero

Our most popular window solution suitable for low to medium secure facilities has been redeveloped. The Humber™ Zero now has smaller sightlines, allowing for increased light transmittance and increased airflow. We’ve kept all of the main features whilst improving the finer details, further increasing it’s levels of safety and security.

The Humber™ Zero consists of an external sliding sash operated by a reduced ligature rotating knob, with access to the external sliding sash being restricted by an internal Stainless Steel Removable PolarMesh. The PolarMesh is removable only by the maintenance department, to allow cleaning of the internal face of the sliding sash, deep cleaning of the PolarMesh, or to replace the PolarMesh. The external sliding sash has the option to be locked at 3 positions (Fully Open, Midpoint or Fully Closed) to allow staff control over the levels of natural airflow and temperature of the room. To aid safety & security of the window, there are no glazing beads.
