SIZES AND THICKNESSES,WHERE THERE ARE NO SPECIAL REQUIREMENTS FOR
THE SHEET GLASS, BEYOND SIMPLE TRANSPARENCY.

6. CONCLUSIONS
• IN CONCLUSION, THE MAIN DIFFERENCE BETWEEN A TRADITIONAL AND ANEXTRA-CLEAR FLOAT
GLASS IS THE TRANSPARENCY OF THE LATTER, WHICH ALLOWS A HIGHER LIGHT TRANSMISSION.
• LIGHT TRANSMISSION IS EXPRESSED IN % AND IT IS THE QUANTITY OF LIGHT THE GLASS LETS
THROUGH, THIS WAY GIVING GREATER CONTRIBUTION TO THE NATURAL ILLUMINATION OF THE
ROOM.
• THE EXTRA-CLEAR GLASS, THANKS TO ITS TRANSPARENCY, IS ALSO VERY OFTEN BACK-PAINTED. IN
FACT, THERE IS VERY LITTLECOLOUR VARIATION THROUGH THE GLASS.
• THE USE OF EXTRA-CLEAR GLASS IS OPTIMAL IN THE FURNITURE FIELD,ABOVE ALL FOR THE
PRODUCTION OF SHOWCASES FOR JEWELLERY.
• THE ONLY DIFFERENCE BETWEEN TRADITIONAL AND EXTRA-CLEAR GLASS, IN NEGATIVE TERMS, IS
THE COST. THE EXTRA-CLEAR COSTS ABOUT 30% MORE, ON AVERAGE.
