Grooved storm window or door requiring a gasket or spline

1/8" is usually reqd to  match  original glass thickness

Answer 3

Do not use plexiglass to replace a window glass pane if you want it to perform well.  over time the plexiglass will become cloudy.  Also the heat from the sun will cause the plexi to sag and move which will break the seal which in turn will cause condensation.
