Differences between Alu-Gard and Alu-Gard Edge?

Its all in how the mesh is held into the frame, Alu-Gard Edge has no visible fixings holding the mesh.

This provides an extremley effective, strong and asthetically pleasing finish to an already tried and tested system. Your KNA representative can show you samples at the time of quoting.
