I'm thinking about using magnafix tape to fix acrylic sheet onto the outside of aluminium windows as a secondary glazing system. Clearly, that won't work unless I can stick a steel tape onto the window first! :) Any suggestions? Thanks so much.
Using Magnafix you put the A tape on the window frame and the B tape on the acrylic, thereby joining two non-magnetic surfaces with magnetic strip on each. Please note adhere the magnet to either the window or perspex then place the opposing magnet on to it. Peel the self adhesive strip off and push onto required surface.
