Browse Forums Windows & Doors Re: Crimsafe vs Invisi-gard vs Amplimesh 5Oct 01, 2020 12:56 pm KNA Security InvisiGard is a fully insulated system using marine grade steel, Crimsafe doesnt. Crimsafe is what everyone hears due to the advertising. Amplimesh is good also and uses marine grade mesh, although InvisiGards frame is a heavier frame. Other things to consider would be locks, Whitco, Lockwood, Doric, Austral etc. IMO Lockwood is the better. Definitely. We have Clearshield doors and the Whitco locks all failed within a year of installation. For what it's worth there's no way I recommend Clearshield doors |
