Glass block flooring 

Glass blocks flooring is used in all types of situations from bridge walkways, mezzanine floors, balconies, corridors and public highways outside buildings, allowing natural daylight to flood below.

Glass floor blocks* and lenses used in horizontal applications are specially manufactured and differ from glass blocks used in vertical walling.

The most common way to specify or install glass block flooring is to use precast, manufactured to order under factory-controlled conditions to suit individual project specifications such as glass block flooring, precast floor panels, roof lights and pavement lights.

Precast glass block flooring ensures:

  • Factory-controlled conditions of manufacture
  • Correct quantity, gauge and positioning of reinforcement bars to specified loadings
  • Consistency of premixed mortar to provide calculable mortar strength
  • Vibration in special moulds to improve strength
  • A dry trade product delivered to site that can be installed in minutes 

Floor glass block characteristics

Solid, hollow, floor glass blocks are manufactured in the same way as wall blocks. They have a thicker face, are annealed for longer (like toughened glass) increasing the surface strength, also the face is totally flat where a wall glass block has a slightly concaved rim close to the edge of face.
