For a rough guide of what thickness of plastic sheet to use on your size of window, bearing in mind that certain products have a restricted range of sheet (e.g. Trackglaze) but others offer a choice (e.g. Magnetglaze and Magnetglaze Extreme), we suggest these guidelines:
- 2mm Sheet - Small windows - up to 1m sq
- 3mm Sheet - Medium - 1m to 1.5m sq
- 4mm Sheet - Large (1.5m - 2m sq) and Extra Large (2m sq+)
- 5 or 6mm Sheet - use only with Magnetglaze Extreme products and Clipglaze
