Foam Glass gravel

GLAMACO plan and deliver:

  • Complete and turnkey production lines in accordance with the customer requirements
  • Options
    • batch plant (dosing and mixing equipment)
    • glass powder production with milling and drying
  • Test with the customers materials to check the usability  for foaming process
  • Basic engineering for the production building and all needed facilities, check of the feasibility of using existing buildings.
  • Erection and commissioning of the complete equipment (together with customers staff)
  • Training of customers staff

·         Startup procedure and production support until contract productivity is reached


Standard production line with  120.000 m³/year

Furnace for Foam Glass Gavel

Foaming furnace, indirect heated

Dosing system for batch, transport system conveyor belt, several heating sections, ecologically harmless (indirect) heating, separated waste gas discharge, cooling sections, maintenance friendly construction of furnace

Foam glass gravel in its viscous state is a glass swelled by gas formers and congealed to solid foam by annealing characterized by a high heat insulation factor, pressure resistant, water and frost resistant


Foam glass gravel is used as an high-end insulating

material for the following applications:

            - insulation of platform and terrace roofs

            - green roof thermal insulating with drain function

            - insulation for special applications

                        (swimming pools, tunnels)

            - intensively insulating outside wall facings

            - insulation for long-distance heating pipe lines

            - insulation of underground storage tanks

                        (water, fermentation gas)

            - acoustic protection

Foam glass gravel is made from 100 % recycled glass


- density:                                            150 – 200 kg / m³

- bulk density                          100 – 150 kg / m³

- thermal conductivity:                                   0.06 – 0.08 W / mK    

- specific thermal capacity                850 J / kgK

- compression strength:                     0.78 N / mm²

- water vapor permeability:                vaporproof

- color:                                                grey

- dimensional stability at defined

  temperature and moisture               < 0.2 %

- building material class                     A1      


Use of scrap, recycled or waste glass

Sorting, cleaning, drying before use; for 1 m3 foam glass it needs approx. 150 … 200 kg scrap or waste glass

Batch plant

Milling the glass and mixing the powder with foaming agents

For example:             - SiC

                                   - MnO

                                   - Na2Si3O7

                                   - soot or coal powder

                                   - CaCO3

                                   - CaSO4
