Fixed window security screens in the Kimberley, Darwin NT

Fixed window security screens are becoming more of a requirement for the security conscious home owner in the Kimberley and Darwin, NT. New homes and renovations often incorporate large windows as features in the overall design of the home. To cover these windows in conventional security grilles would detract from the visual appeal of the home and as a result, security is often not adequate.

Invisi-Gard Fixed Window Security Screens combine the proven strength and security of 316 Marine Grade Stainless Steel Mesh with extruded aluminium perimeter framing to create a security window screen that looks great whilst providing excellent security.


Hinged & Sliding Security Doors in the Kimberley, Darwin NT

Hinged and Sliding Security Doors are growing more popular in new and renovated homes in the Kimberley and Darwin, NT. Many homes incorporate one or more sliding doors or hinge doors as part of the access entry, entertainment areas, back yards and patios. In the past it has been difficult to add security doors that do not detract from the views or value of a timber entry door.

Invisi-Gard Hinged or Sliding Security Doors offer excellent security without compromising the vision through the door.

316 Marine Grade Stainless Steel Mesh is used in all Invisi-Gard Stainless Steel Security Products and it is because of this Marine Grade Stainless Steel that Invisi-Gard out performs all other stainless steel security products when it comes to corrosion resistance.
