Wissmach have a collection of 96coe glass. There are various opinions whether this range is fully compatible with Oceanside (formerly Spectrum) 96coe but our studio mixes them and haven't had any problems so far.
Wissmach glass isn't as smooth or as well annealed as Oceanside glass but it is generally much more cost effective.
We have decided to offer Wissmach glass in several size variants.
300 square to match Oceanside (this is more expensive as it doesn't utilise the sheet efficiently)
270 square which maximises the Wissmach sheet but isn't always big enough for a project
270x135 to sell the offcuts
