Laminated safety glass has good industrial potential due to its multiple advantages in commercial and industrial applications though the product is not as popular as toughened glass. The main applications of laminated safety glass are:

  • Automobiles,
  • Railways,
  • Marine vessels,
  • Aircrafts,
  • Defence,
  • Household construction applications, and
  • Other industrial applications.

The main advantages of laminated safety glass are:

  • On accidents the glass does not harm/injure the body,
  • It acts as a good insulator,
  • It is sound proof, and
  • It has got a good strength compared to toughened and other sheet glasses.

Laminated safety glass is a sandwich made up of a PVC interlayer or interlayers adhered between two glass sheets. Laminated glass is more resistant to fracture than monolithic glass, but in case of fracture, the PVC interlayer holds the fragments in place.

Market Potential

There is a very good demand for setting up this product in small scale sector, in commercial and industrial applications. The main consumer of these products are Railways, Automobiles, Defence, Aircrafts, Marine vessels and in domestic applications. The growth of laminated safety glass industry depends upon the development of automobile industry and also in construction of multi-storeyed buildings. As the automobile industry is steadily growing, the demand for laminated safety glass is also increasing. Besides this, there is considerable demand for laminated safety glass as spares for replacement purposes. Therefore, there is good scope for setting up new units.

Basis and Presumptions

  • The production capacity of the unit has been worked out on the basis of single shift basis of 8 hours per day for 300 working days in a year.
  • The unit is capable of manufacturing the laminated safety glass sheets in different shapes, sizes and thickness.
  • The costs of machinery, equipments and raw materials are as prevailing at the time of preparation of this report.
  • The wages proposed in the profile as per the prevailing wage practice.
  • The rate of interest of 13% is considered both for recurring and non-recurring investment.
  • Margin money is generally about 25%, however, this varies according to the type of entrepreneur.
  • Operative period of the project is around 12 years considering technology obsolescence rate and period of repayment of loan.
  • To achieve full plant capacity 1 to 2 months trial production is required.

Technical Aspects

Process of Manufacture

The raw materials for manufacturing the laminated safety glass are ordinary sheet glass/float glass and PVC sheet. Sheet glass/float glass suitable for this product should be of good quality i.e. free from stone, weariness, stresses, strains, scratches and other surface defects. The important stages in the manufacture of laminated sheet glass are:

  • Raw glass sheet inspection
  • Glass cutting
  • Glass washing
  • PVC interlayer cutting
  • Preparing the resin
  • Assembly of sheet glass and interlayer
  • Pouring resin on each side of the PVC between it and the glass
  • Rolling and pressing
  • Drying
  • Edge finishing
  • Final inspection
  • Packing

Quality Control and Standards

Quality Control and Standards Generally quality product should be free from defects and foreign materials which creates problems when it is in use. These defects can be controlled at every stage of the operations of the process by thorough checking, right from raw materials selection to finished products and packing.
