A. Opti-White, or Low Iron glass as it is also known is the clearest type of glass available. When viewed from the edge the glass appears to be a light blue colour in comparison to Clear glass which appears green.

Krypton - This is option provides the greatest level of energy efficiency
Argon - This is option provides a reasonable level of energy efficiency at a more affordable cost.
Q. I require glass made to an irregular shape, how can i order this?
