What the AI looks for in Plate Glass

Annealed vs. tempered vs. laminated
Use tempered or laminated glass wherever codes require safety glazing: doors, showers, tub surrounds and low glazing near floors. Annealed glass is fine for picture frames and protected cabinet panels. Tempered glass breaks into small pieces, and laminated glass stays together; annealed glass breaks into sharp shards.
Cutting before tempering
Order tempered glass cut to final size, with holes and notches already made. It cannot be cut, drilled or edged afterward. Any cut or drilled hole in tempered glass shatters the entire sheet.
Thickness for use
Use thin glass (about 1/8 inch) for frames and small panes. Use 1/4 inch or thicker for tabletops and shelves, increasing thickness with span and load. Glass that is too thin for its span deflects and breaks under load.
Edge finish
Seamed edges are fine for framed glazing. Exposed edges on tabletops and shelves need a polished or flat-polished edge. Raw cut edges are sharp and chip easily.
Clarity
Choose low-iron glass when the green edge tint of standard float glass would show, as in display cases, thick shelving or white backgrounds. Standard float glass has a visible green tint that becomes stronger as the glass gets thicker.

Brands that matter

  • Vitro: Starphire low-iron glass; formerly PPG's flat-glass business.
  • Guardian: Float glass and UltraClear low-iron glass.
  • Pilkington: Float glass and Optiwhite low-iron glass, plus safety glass products.
  • AGC: Global float-glass maker of clear, low-iron and laminated glass.
  • Plaskolite: Acrylic sheet (Optix) for when shatter resistance and DIY cutting beat glass.

What to avoid

  • Trying to cut or drill tempered glass.
  • Using annealed glass in doors, showers or near the floor.
  • Exposed raw cut edges on tabletops or shelves.

Questions

Is plate glass the same as float glass?

Practically, yes. Modern flat glass sold as plate glass is made by the float process.

How do I know if glass is tempered?

Certified tempered glass carries a small etched mark in a corner. If there is no mark, assume the glass is annealed.
