Edge Polishing

BuyGlass.Co pride ourselves on creating a beautiful end product. With edge polishing there are a few things to consider before you purchase & when evaluating the glass you receive.

Depending on the process used, the edge finish can vary slightly between panels. All BuyGlass.Co edge polishing is finished to an exceptional standard and fully QC'd before release.

If you require a uniform finish across all pieces then please contact us after the order is placed.

Otherwise we will process the polishing using whichever process we choose, and although generally this would mean all glass uses the same polishing technique there are certain times when we may use various methods.

Glass Corners

Corners are supplied, as standard, with dubbed corner. If you require unfinished or radius corner please let us know.

Laminated Glass

We use multiple methods for creating laminated glass. CIP, SGP, PVB & EVA are totally different processes which produce very similar results. CIP however, due to the injection process, has a faint area at the perimeter which can be seen upon closer inspection.


If you would prefer any particular method then you must let us know prior to production or else, at our discretion, we will use any method.
