Invisi-Gard mesh is contained within the frame by pressure-based wedges.

Invisi-Gard mesh by Alspec

Invisi-Gard is a unique, patented security solution for doors and windows incorporating GR316 marine grade stainless steel mesh as the infill material.

A system of pressure-based wedges is the primary means of retaining the mesh within the aluminium frame.

Invisi-Gard enjoys a range of applications from residential security screens for the home to commercial screens for the security of business premises. The system has been successfully used in defence, schools, hospitals and other government projects. The choice of materials and the construction method ensure that Invisi-Gard retains its pristine appearance for many years with a minimum level of maintenance.
